SOFTWARE
controlling deviations in a misra compliance environment C and C++ are by some distance the most widely used languages for embedded software development. Recent research by VDC shows C being used by 70% of the embedded systems companies surveyed and C++ by 42%. C has been implemented for virtually every processor. It provides a wide range of resources and libraries, and is supported by a wide range of tools. The C language, in particular, allows the developer to do many things which are essentially incorrect. It is all too easy to write code which conforms to the language standard but which will result in either program failure (i.e. a crash) or undefined behaviour. Common examples are code which results in accessing memory outside the bounds of an array or an arithmetic operation which results in integer overflow. Author: Fergus Bolger, cto programming research ltd
The Philosophy of Coding Standards The industry-accepted way to tackle these hazards is to adopt a Coding Standard. In their simplest form, coding standards define a set of consistent coding practices. Although uniformity of style can be valuable within a software project, they do not address the important attributes of software quality such as reliability, portability or maintainability. The more fundamental role of coding standards is to define a safer subset of the programming language by framing a set of rules which eliminate coding constructs known to be hazardous. The MISRA coding guidelines, embodying this principle of safe sub-setting, are now accepted world-wide as the benchmarks for developing safety-critical software in C and C++. They have been widely accepted because they are concise and readable and because they focus on essential issues. A very recent poll (Ganssle, 2014) of 500 respondents revealed some interesting data on coding standard adoption rates. The main finding suggested that about 60% of all coding standards in use are MISRA-based. The strictness of adoption was another interesting finding, with MISRA-based coding rule sets achieving 75% consistent use within the development team, whereas other rule sets achieved less than 50%. The Principle of Deviation MISRA coding standards contain widely respected guidelines for developing in C and C++ languages. These guidelines focus 12
EP&Dee | September, 2015 | www.epd-ee.eu
on issues which are important when developing critical software systems. MISRA also recognizes that, in some situations, it is unreasonable or even impossible to comply with a coding guideline and that it is necessary to deviate from certain rules. A deviation states the reason for not complying with a particular coding rule in a certain circumstance. It also provide a rationale and description of the extent to which the particular rule is being relaxed, and supplies a properly constructed safety case that includes mitigation against the effects of not complying. However, in the absence of a carefully stated scope for the non-compliance, a basic deviation facility could be misunderstood or abused and ultimately undermine the efficacy of the guidelines. Constraining the Use of Deviations In the same way that coding standards themselves need objective creation and wellunderstood rationales, the reasons given for deviating from coding rules similarly need a common expression and agreed interpretation and a precise scope for their application. The automotive industry, the original and still leading application domain for MISRA, has faced up to this requirement. Both MISRA itself and one national body, the Japanese Automotive Manufacturers Association ( JAMA), have each begun the process of setting out the conditions under which to permit specific deviations from full MISRA compliance.
The thrust of this work is to define a set of rule deviations that are tightly constrained in scope. An important first stage is to categorize the broad reasons for deviation from rule non-compliance. Categorizing Deviation Reasons By breaking deviations down into the following categories, the practical difficulties with compliance are made more apparent. Additionally, this categorisation guards against inappropriate deviation and weakening of the coding standard intent. a) performance: It may seem strange and non-intuitive to suggest performance as a reason for not following good coding practice, but the following real-life situation demonstrates the need: As part of the vehicleâ&#x20AC;&#x2122;s engine control system, a timing variable needs to be accumulated at regular intervals. The code, correctly formulated to meet MISRA-C:2012 Rule 10.6 (value not to be assigned to a wider type), reads: extern uint16_t qty, time_step; uint32_t prod = ( uint32_t ) qty * ( uint32_t ) time_step; The casts ensure that the 16-bit operands will not overflow in the 32-bit multiplication for this compiler. However, the compiler performs this operation using â&#x20AC;&#x153;shift and addâ&#x20AC;? mode of long multiplication rather than the IMUL (signed multiplication) mode it is equipped with. The compiler vendor has clarified that IMUL mode only occurs on implicit conversion, requiring the expression to read: uint32_t prod = qty * time_step; // deviate from Rule 10.6
DESIGN
By permitting implicit conversion in this case, the single clock cycle IMUL operation is guaranteed, rather than the ~100 clock cycle worst case execution of the former, thus justifying a controlled deviation on the basis of performance.
b) external (third-party) code: This category includes common libraries, auto-generated code, and legacy internal code modules or even just a complex function encompassing a key application algorithm. Maintainers of public-domain libraries, given their broad application domain, rarely have the motivation to comply with MISRA or other coding standards. Auto-generated code, unless it meets a functional safety standard like ISO 26262, will likely contain inherent MISRA violations. Legacy code may pre-date the project’s adoption of MISRA. The impact analysis of possible refactoring to meet MISRA rules may itself raise a concern. The safety case in all these situations is based on “qualified through use” reliance in combination with specific other quality measures. c) build configurations: A particular feature of automotive supplier applications is to provide many variants of a single codebase according to customer need. Rather than build-level control of this delivery, configuration mechanisms are deployed to control feature delivery for each variant. As a result, MISRA compliance can suffer in terms of redundant code, invariance in expressions, and related global issues. d) access to hardware: In order to access registers, address absolute memory and control interrupts, embedded developers need access to compiler-specific extensions to the C language, resulting in MISRA noncompliance. The safety case will typically require careful unit test coverage. e) defensive coding: Given the absence of robust exception-handling in C, defensive coding practices may involve, for example, programmatic guards against unforeseen behaviour. A fully capable analysis tool will correctly detect invariant conditions and unreachable code as a result. The safety case must involve forced unit test execution of these paths or conditions. f) language features: There are valid code quality reasons to use ‘recent’ language constructs, for example Boolean or ‘long long’ types or inline functions. However, these can require deviation from older versions of MISRA. The safety issue is that even 15-year old C99 constructs are not guaranteed to be supported by all compilers. Structure of Controlled Deviation Categorisation of the different rationales is a first step in creating a properly constrained
SOFTWARE
deviation structure. This leads naturally into an elaboration of all specific known deviation cases, by rule and by category. MISRA and JAMA are both documenting, with industry participation, documenting a set of rule
When choosing the specific code location where a reported diagnostic is to be suppressed, developers must be constrained to only suppress using the permitted range of controlled deviations.
Figure 1: tool enforcement of controlled deviation scope restrictions, each with detailed justification and safety case. Even outside of an automotive context, these initiatives are important. The MISRA coding standard was originally designed for the automotive sector, but from its early years it found willing adoption in many other embedded environments, from consumer products to medical devices, industrial control to EDA. Equally, the establishment of a controlled deviation structure is important in any industry or organisation adopting coding standards. Automated Tool Support A coding standard without an automated means of enforcement and a rich audit and reporting capability will soon become a bookcase adornment, rarely referenced or followed. The starting point for a competent automated static analysis tool must be accuracy in its diagnostic output, clarity of comprehension and explanation on each issue raised, and detailed reporting against every version of the software project. But even an environment of automated tool enforcement needs awareness and application of an approved deviation policy, especially since this removes one impediment to full compliance. Both the coding rules and the deviation policy must be convenient for developers, trusted by leads and managers, and facilitate detailed QA reporting. A basic deviation system will couple each instance of rule suppression to its supporting deviation, and preserve this coupling through the lifetime of the relevant source code. The requirements are more complex when dealing with controlled deviations. Any suppression of the relevant coding rules must obey the tighter restrictions in force, and no suppression may take place outside of that controlled set of deviations.
Summary The MISRA C coding standards are synonymous with safe and defensive use of C in many embedded environments and beyond. Being both comprehensive and wide-ranging in the restricted use of the C language, a system of controlled deviation is now recognized as a necessity, as exemplified by various industry and community efforts to specify such curtailment. In this article, we have explored the categories of deviation, and seen how legitimate specific reasons for deviation are now being crafted for industrial use. Sophisticated and automated tooling support for the controlled deviation initiative along with reporting and other elements of a compliance solution are available today. bibliography Ganssle, J.

M2M
Wireless design challenges in the fast-growing m2m market By Stefano Moioli Director Product Management Cellular, u-blox aG Thomas Nigg Senior Director Product Strategy Positioning, u-blox aG
Thomas Nigg has served 15 years at u-blox, 6 years as Manager of Technical Support, and 9 years as Senior Direct Product Strategy. During this time, he has built up considerable knowledge and led a team of specialists in the areas of embedded satellite positioning receivers and cellular modems used for automotive, industrial and consumer applications. The rate of growth of machine-to-machine (M2M) connections now far exceeds new connections between people and very soon there will be many more machines than people connecting over cellular networks, as shown in the GSM Association forecast illustrated in Figure 1. These machines include security systems, meters, robots, vending stations, asset trackers and emergency call systems. The variety is growing by the day, as are
the silent conversations between millions of machines exchanging data 24 hours a day, 7 days a week, with no human intervention. At the same time, itâ&#x20AC;&#x2122;s becoming cheaper and easier to connect to the Internet and even mass produced computing devices are able to gather and process ever-larger volumes of data. The one potential bottleneck to greater M2M connectivity, the fact that all 4 billion+

IP version 4 addresses are already allocated, has been removed with the introduction of IP version 6. This supports 2 to the power of 128 addresses, more than enough for every grain of sand on Earth to have its very own address. Itâ&#x20AC;&#x2122;s perhaps no surprise then that LTE, the fourth generation of mobile networks (4G), is designed to deliver services such as data, voice, and video over IP version 6.
DESIGN
To join the M2M networking revolution, all that’s needed is to embed machines with small, economical (wireless) modems. Where location, speed or navigation information needs to be established, the machines also need a Gps (Global Positioning System) or Gnss (Global Navigation Satellite System) receiver. Both components, with an antenna, can fit easily in a device much smaller than a mobile phone. (GNSS is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. It includes GPS(United States), GLONASS(Russia) , Galileo(Europe), Beidou(China) and other regional systems. When thinking about how to equip a machine with communications capability, you need to start by thinking about the needs of the application. Factors such as product longevity, geographical network coverage or future-proofing to take account of future wireless network upgrades, 2G to 3G to 4G etc., are all important considerations. Here are some of the product features you need to consider when selecting wireless modems: 1 battery life is critical The time between battery charging or replacement is critical to the success of some products. A container-mounted tracking device, for example, may be required to run for several days if it’s being shipped by air or road, and up to several weeks if shipped by sea. Battery life must be adequate to support these timescales. Mobile phones are typically expected to run for 2 or 3 days on a single charge. As a result, consumer expectations for the operating life of health and fitness devices will be similar. When comparing modem and GNSS receiver specifications in these applications, both the operating and standby current consumption are important, so are power-saving functions. The latter may include auto-wakeup features and intelligent power-saving modes such as the ability to log data autonomously without waking the host processor. Ideally, components should only wake up when needed.
M2M
required to work in all regions of the world and should include either a quad-band or dual-band GSM modem (depending on the location), or 6-band UMTS modem. 3 certified modems accelerate product approvals Any cellular network device, whether for GSM, UMTS or LTE, needs regulatory, industry and operator certification. It significantly simplifies and speeds up the certification process if the modem embedded in the device is certified. 4 What you need today may be different tomorrow While GSM/GPRS networks are perfectly capably of handling the small volumes of data transmitted in remote metering applications, GSM bands are already being considered for re-allocation to 3G and 4G services. To save the expense of future it can be a good idea to design with future technology standards in mind. Today, this means designing with UMTS/HSPA or LTE modems, or at least future-proofing your hardware to make upgrades easier.
Nested design simplifies technology upgrading Cellular M2M technologies are in continuous evolution and, when designing a new device enabling cellular connectivity, it is of essence to take into consideration its upgradability to newer technologies in order to optimize the design cost. Here, there is layout compatibility across the entire range of cellular modems (GSM, UMTS, CDMA and LTE). With this approach, a single printed circuit board layout can be used for all end-product variations ensuring an easy migration between cellular technologies and module generations, also thanks to the AT command compatibility within the different modules 5 bandwidth requirements rarely decrease The bandwidth demand of tracking applications only goes in one direction – upwards – so it’s important to consider the lifetime costs of your connection. Choose your modem based on what it may need to do 35 years from now, or at least choose one that makes upgrades as easy as possible.
Figure 2: nested design techniques optimize design cost and facilitate easier hardware upgrades.
2 mobility demands multi-standards compliance Global mobility is increasing for people and goods, so it is important to consider where a modem needs to function today and where it may be required to work in the future: GSM is supported by four main frequency bands worldwide, UMTS by 6 and LTE over 30.

6 automotive special needs In vehicle-mounted systems, temperature, humidity and vibration can be extreme. AEC-Q100 qualified devices manufactured in ISO/TS 16949 certified sites will ensure reliable, long-life operation. Qualification tests for each component should conform to ISO16750: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”. This applies to vehicle-mounted devices and industrial devices that operate in demanding environments such as ships or railcars. 7 emergency call systems are growing in popularity Increasingly, cars are fitted with systems that automatically report accidents or aid recovery after theft. The US, Europe, Russia and Brazil have established initiatives to support such systems and that will increasingly be required by government mandate. For these applications, and example of which is shown in Figure 3, an “In-band modem”, is often needed. It sends data over the modem voice channel in a similar way to a fax machine sending data over the telephone lines. It’s needed because operators prioritize voice over data in mobile networks. In the event of an accident, the voice channel becomes the crucial link for transmitting data to emergency services. Check that your proposed solution supports in-band modems on both 2G and 3G networks. 8 assisted positioning in urban environments In cities or other urban environments where satellite may be blocked by tall buildings, the drop-out of positional overview can be overcome by calling up a remote A-GPS server. This is a simple process that downloads a few bytes of satellite orbital data from the
M2M
Internet using a wireless modem. With this aiding data, visible satellites need only be visible for a few seconds to calculate a position, and not the full 30 seconds it takes to receive an entire 1500 bit satellite frame. Check that the positioning (GPS) receiver vendor offers online assistance with guaranteed availability and that this covers the geographic regions of interest. Client software should support the service transparently and the positioning receiver and wireless modem should both have an interface to support the service. It’s also increasingly important that the service is available for both GPS and GLONASS. 9 dead reckoning support to extrapolate positioning data from sensors Satellite signals can be supplemented with Dead Reckoning support, which extrapolates location and speed based on data from vehicle sensors, as illustrated in Figure 4. This approach helps determine vehicle position in tunnels or other locations where satellite reception is temporarily unavailable. It’s useful in vehicle-based telematics, including insurance tracking systems, where it accurately records position, heading and velocity. Check that positioning receivers are automotive-grade, support Dead Reckoning and can be plugged into the vehicle CAN bus to acquire the data. Also, will they interface directly with vehicle sensors such as gyros and odometers and does the vendor offer an evaluation environment to speed product development. 10 indoor positioning is possible by combining satellite and cellular data Where an approximate indoor position needs to be established, combining a satellite receiver with a wireless modem overcomes the problem of satellite signals being blocked by walls or other obstructions. This hybrid
Figure 3: in-band modems are required for emergency call systems like these so that data is transmitted over prioritized voice channels. 18
EP&Dee | September, 2015 | www.epd-ee.eu
solution exploits the visibility of 2G or 3G cells because GSM or UMTS signals easily penetrate walls. Where the boundaries of visible mobile cells are known, an approximate position can be calculated from knowing where the cells overlap. This approach needs a wireless connection to an external service, similar to assisted positioning. Check that your positioning receiver and wireless modem supplier can offer such a solution, that it’s proven and whether it provides an online service. It’s also important to establish that the accuracy of the system is adequate.
Figure 4: dead reckoning extrapolates position data from vehicle sensors, including gyros and wheel tick sensors. 11 positioning system compatibility Until recently, GPS was the only system you needed to consider. Now, there’s Russia’s GLONASS, Japan’s QZSS, China’s BeiDou and Europe’s Galileo to consider. Compatibility with GPS plus at least one other satellite system will be needed to increase system reliability and accuracy, and to fulfill regional government mandates for compatibility with their own systems. Parallel operation that uses two systems simultaneously may be part of the specification. An example is Russia’s new ERA-GLONASS vehicle emergency call system that requires GLONASS compatibility. Look for GPS/GNSS receivers that provide multi-GNSS support and provide parallel GPS/GLONASS or GPS/BeiDou reception. These are just some of the considerations when adding wireless connectivity to M2M products. Remember that many new standards, both wireless and positioning, are in transition. It’s important to consider the operation of your product over its lifetime and which markets your products will to serve. Also consider whether it’s important to include design support for next-generation performance and network coverage, or opt to design for easy upgradeability of your products in the field ■ u-blox www.u-blox.com

u-blox introduces a portfolio of cost-efficient LTE Cat. 1 modules for M2M and automotive applications
u-blox introduces TOBy-L201, a 150 Mbps 4G LTE and WCDMA module with multi-carrier support
u-blox announces a portfolio of new LTE low data-rate cellular modules supporting LTE Cat. 1 for IoT and M2M applications in the industrial and automotive markets. Major carriers are rolling out LTE networks worldwide at an accelerated pace, considering the sunset of their existing 2G and 3G networks. Devices that are expected to operate for years to come need to incorporate LTE technology in order to ensure longevity. The portfolio consists of multi-mode, multi-carrier and of LTE-only modules specific for large North American carriers. All modules provide longterm LTE technology at lower speeds, ideal for industrial and connectedcar applications (10Mb/s download, 5Mb/s upload), at a significantly lower cost than typical LTE Cat. 4 modules. All modules operate from -40°C to +85°C, making them suitable for demanding industrial and automotive devices. The unique combination of performance and versatility makes these modules ideally suited for M2M applications, such as telematics and smart metering, as well as security and surveillance systems with the need for Voice-over-LTE (VoLTE).
u-blox announces TOBY-L201, the world’s first 4G LTE Cat 4 module with 3G WCDMA fall-back, which works on AT&T and Verizon networks. TOBY-L201 switches automatically or via AT command to AT&T’s or Verizon’s network, without the need to load new firmware. Depending on which carrier’s SIM card is inserted, TOBYL201 recognizes the carrier and starts on that carrier’s network. If devices are equipped with two SIM cards or a configurable SIM chip, TOBY-L201 can be switched between operators on-the-fly via a simple AT command.
“Building on our philosophy of customer-driven innovation, u-blox is once again delivering a competitive advantage with cost-effective and long-term solutions for IoT and M2M applications. The new Cat.1 modules will enable our customers to develop devices supporting LTE technology at an acceptable cost, because LTE Cat. 1 delivers lower speed at a lower cost,” explains stefano moioli, Director Product Management Cellular at u-blox. “We expect LTE Cat. 1 technology to become the future norm for M2M applications,” he adds. the u-blox lte cat. 1 module portfolio includes the following variants: • TOBY-R201 (LTE bands 2, 4, 13, 17 and HSPA bands 2, 5) is a multimode, multi-carrier LTE Cat. 1 module with HSPA fallback for North America. Its form factor in a 24.8 × 35.6 mm2 LGA package is the same as the TOBY-L2 Cat. 4 modules designed for applications requiring high data rates. The first samples will be available in October 2015. • LARA-R200 (LTE bands 4, 13) and LARA-R202 (LTE bands 2, 4, 17) are LTE Cat. 1 modules for the largest North American carriers, available in a compact 22.0 × 27.5 mm2 LGA form factor, and fit on the nested design pads compatible with other u-blox form factors. The first samples will be available in early 2016. Additional variants for Europe and APAC are planned. The modules also follow the u-blox “nested design” philosophy to maintain form factor and software continuity.

3D GESTURING
three-dimensional Gesturing The Evolution of the User Interface The advent of modern desktop operating systems such as Microsoftâ&#x20AC;&#x2122;s Windows and Appleâ&#x20AC;&#x2122;s MAC OS created a need for more than just a keyboard and while the mouse was the default device for desktop machines, portable notebook computers relied on something more integrated. Originally the options were a trackball (essentially a mouse turned on its back) or an isometric joystick. However by the early 1990s these somewhat clumsy options were replaced by the more intuitive touchpad. Since then, touchpads have evolved to offer multitouch detection and capacitive sensing, but they still require a considerable amount of space while only detaching in two dimensions.

Using an innovative technique called E-Field, which uses near-field RF technology, Microchip has developed GestIC; a 3D gesture control technology that overcomes the limitations of existing touchpad solutions. Integrated in to a single-chip, the MGC3130 creates an electrical field that can detect in 1D (presence) 2D (touchpad) and 3D (gesture) to provide contact-free position tracking, gesture recognition and approach detection for a range of applications (Figure 1). Technology Overview The electrical near-field sensing technology employed by GestIC uses a carrier frequency of around 100kHz, which equates to a wavelength of about 3km. However, in its implementation, the distance between the electrodes is much smaller than the wavelength, which allows the magnetic field component and radiated energy to remain at practically zero. This results in a pure quasi-static E-Field that doesn’t create interference in the radio spectrum used by other devices, such as mobile phones. Furthermore, unlike other sensing technologies sometimes employed to create 3D user interfaces — such as optical, ultrasound or infrared — E-Fields are not affected by light, sound, skin colour, humidity or other ambient parameters.
3D GESTURING
Any movement within the E-Field is detected and translated in to X and Y co-ordinates; moving objects can, therefore, describe gestures which can be recognised. The device can control up to five receiving electrodes to acquire positional data, this is then processed by the onchip Signal Processing Unit (SPU) and, when used with Micropchip’s free Gesture Library software (Figure 2), allows the MGC3130 to detect and decode a wide range of gestures. With a positional update rate of up to 200/second, the five electrodes allow a vast number of data points to be acquired. Integrating the on-chip SPU and library on-chip means a truly realtime gesture recognition system can be realised in a single chip. The low power modes available allow an ‘always on’ solution even when implemented in battery powered devices; even in the lowest power mode, approach detection is still enabled, allowing maximum power savings without sacrificing responsiveness or functionality. Because position data is acquired in three dimensions (X, Y and Z) and processed on-chip to deliver real-time response, users can experience a more immersive interface which is more intuitive and more responsive that existing alternatives. For developers, interfacing to the MGC3130 is also simple, using a 4-pin interface that supports SPI, I2C and more.

Existing ‘free space’ detection systems rely predominantly on optical sensors. However, these face a number of challenges, such as angular related detection and coverage. In addition, the average power of optical-based systems can be over 500mW for even rudimentary 3D functionality, while the 50frames/second update rate presents real-time issues. The E-Field solution, on the other hand, requires less than one tenth of that power and offers significantly higher update rates. Free-Space Keyboard With a dedicated ‘Overkey3D’ solution, GestIC can also be used as an alternative to traditional keyboards in notebook and even desktop computers, be creating a 3D sensing space within existing keyboard designs. This could, for example, allow motions to be detected as pre-defined gestures mapped to specific parts of the keyboard, creating a unified keyboard and input device that uses hand gestures to control functions. Figure 3
This approach is already supported by Windows 8; hands may never need touch or leave a keyboard to achieve touch command input, allowing position tracking while fingers glide across the keys. Radical as it sounds, this could support control in free space; gestures that
are already available within Colibri Suite. The technology also supports the combination of two GestICs in a ‘master/slave’ configuration (Figure 3), allowing dual-zone control. The GestIC API provides full support for 3Rd Party software developers targeting Windows. As it supports low-power approach detection, developers can implement effective backlight control based on presence detection that instantly switches key LEDs off or on, eliminating the need to wake a device with a key press. This approach also supports power conservation, as the LEDs can be switched off as soon as the presence (hand, finger etc..) is removed, instead of wasting energy through a timer-based LED off signal. Manufacturers of ‘all in one’ PCs are currently looking to innovate the Human-Machine Interface (HMI) in response to the impact that gesture-enabled Tablets and the Windows 8 operating system have had. 3D gesture recognition can support these ‘Metro-style’ user interfaces within the same space as the keyboard, instead of using the touchscreen. This would allow users without a touch-enabled display to take advantage of the Metro Panel features Microsoft introduced in Windows 8, such as the touch gestures to control applications and content; in systems without a touch-enabled screen the UX innovations remain inaccessible to the user, GestICenabled keyboards would open them up to all users, even those using Windows 8 in legacy hardware. By providing gesture ‘shortcuts’ for the most frequently users commands, Windows 8 users can gain significant productivity advantages. Manufacturers looking to innovate at the user interface level can now benefit from advanced, efficient and responsive 3D gesture recognition in a single-chip solution, with dedicated hardware and software resources to enable rapid development of advanced user interfaces.

SINGLE-PHASE MOTORS
Opening doors An explanation of how to complete a low-cost design and analysis using a single-phase AC induction motors and an 8bit microcontroller in a garage door application. Author: Justin Bauer, microchip technology inc.
Small AC induction motors, say for opening garage doors, can have speed control and soft start added with little cost using a threephase inverter circuit. These permanent split capacitor (PSC) motors are among the simplest and widest used for this type of application. They have low starting torque and current, but can be inefficient due to the non-polarised run capacitor, which often fails before the rest of the motor. These single-phase motors are often referred to as two-phase motors because they cannot run without sufficient phase shift between the two windings. The capacitor is placed between the input signal and winding to produce an approximate 90Ë&#x161; phase shift. The switch is often replaced with a relay that can control the direction by swapping which phase leads or lags the other. The value of the capacitor is typically specified by the motor manufacturer and is sometimes in the range of 5 to 50ÂľF for motors that are less than 0.75kW, of the type being looked at here. The capacitor should be carefully chosen to correct the power factor for maximum
power efficiency. Figure 1 shows the topology of a traditional AC induction motor. The voltage rating is typically high at around 220 to 450V, depending on the input voltage. The capacitor must not be polarised, since it is across an alternating voltage. If this capacitor fails, the motor will cease to turn.
ates heat as it consumes the RMS AC ripple current within its equivalent series resistance. The permanently installed capacitor trades off starting torque capability at standstill with ripple torque reduction at running speed. Because of the high VA rating of the capacitor, it is often selected to meet the minimum

The importance of selecting the correct capacitor is therefore critical. A practical capacitor has resistance and radi-
starting performance requirements, resulting in poor running efficiency. For motors that do not have identical wind-
DESIGN
ings, it is necessary to feed the two phases with different voltages. This asymmetry is due to the presence of the capacitor, which forms a resonant circuit with the motor’s inductance. Consequently, this raises the voltage across one of the windings and causes uneven current flow. However, a three-phase inverter can be used to replace the permanent capacitor, as shown in Figure 2. This allows the speed of the motor to be adjusted with the appropriate amount of voltage applied to each winding so that weaker windings are not overdriven.
SINGLE-PHASE MOTORS
shaft the fastest and how quickly the load will accelerate; and efficiency to compare the real component of the output power to the input power and to measure the power factor and other inefficiencies. These three tests cover the largest design considerations in motor control. None of the tests require a special setup from the other tests. Each analysis in the three separate tests can use the same subset of data. The test set up is shown in Figure 3. This test used a 0.19kW single-phase motor with a balanced wiring configuration. Both windings had identical resistance and induc-
quency readings did not produce a constant torque curve. Frequencies lower than 60Hz required a fine tuning of the voltage-frequency ratio because of losses in the motor and inaccuracies in the motor drive. Frequencies below 60Hz were kept at maximum voltage.
tance. A Hall-effect sensor was used to measure the shaft speed. The input was a single-phase, two-wire 220V at 60Hz. The output was fed into the two terminals on the inverter.
The shapes of the curves between the two methods differ greatly. The capacitor method shows a slightly larger starting torque and will accelerate faster than the inverter board at 60Hz. The inverter board produces a curve similar to that of a class D design motor, while the PSC run topology produces a similar class A torque curve. An unequal voltage magnitude caused by the permanent capacitor creates an unequal magnitude of magnetising flux within the stator. The inverter board attempts to create an equal amount of current in each winding, since this particular motor has identical impedance in each.
A low frequency causes a decrease in an inductor’s impedance. The high voltage applied to this lowered impedance raises the current in the stator, which produces higher torque. The fine tuning is needed to make the torque curve linear.
Figure 3: test set-up on the dynamometer. The motor will still spin without the capacitor if the coils are driven out of phase from one another. This can be achieved by creating three phases in software. These threephase voltages can then be referenced from one another to create two resultant waveforms across the two motor windings. One of the phases is taken as the reference, or neutral, to create the two waveforms. The three phases can be created in software using PWM techniques. Comparison Three tests can be run to compare the PSC run method with the inverter method with no run capacitor. These are: torque to characterise the effects of variable frequency drive on the motor; acceleration and speed to identify which method turns the motor
The PC interface ran Magtrol’s M-Test 7 software. The programmable controller applied the test set-up from this software to the dynamometer and read the applied torque. The power analyser performed and logged all the other readings. Starting with the torque test, it was apparent that the motor had the highest starting torque of around 0.75Nm between 50 and 60Hz in line with the motor design. Frequencies above and below 60Hz had lower torque profiles. However, the low fre-

DESIGN
Looking at the starting torque when the rotor is locked, the inverter would be unable to lift the same-sized load as the PSC method if the inverter were programmed to simply turn the motor at a 60Hz modulation frequency. However, the inverter board can use variable frequency drive to lift an even larger-sized load. The designer must also take into consideration the trade-offs of large starting torque versus efficiency and speed. The most obvious benefit of controlling the voltage and frequency is that the designer can control the speed at which the motor shaft spins. The faster it spins, the sooner the load can be pushed or pulled to its destination. This can be a critical design win in a garage door or gating system application. Inverter board So, the inverter board allows the motor to out-pace a replica motor that is driven by the PSC method. The PSC method can only be driven at one frequency and, hence, it cannot exceed its synchronous speed. The inverter board can be constructed as an application-specific platform rather than a general-purpose demo board. However, it does provide numerous inputs and outputs (I/O) for the user to interact with and modify. The inverter is engineered to drive a single-phase or three-phase AC induction motor.
SINGLE-PHASE MOTORS
An overview of the board is shown in Figure 4 using a PIC16F1509 microcontroller from Microchip. The board was designed with flexibility in mind, so some of its features can be used or not to achieve optimisation. Most of the I/O are used by the default code but there is still plenty of space for the developer to use custom modifications. The I2C lines are also free for any added slave devices.
Operation The motor is in its idle state when the PIC16F1509 microcontroller initialises pins and stops the motor. When the start button is pressed, the motor starts using a soft-start method where the frequency and voltage are adjusted in a linear fashion to bring the motor up slowly to its operating speed. The motor then moves to its on state when the soft-start operation is completed.
Some of the I/O are multiplexed onto one pin to increase the number of I/O that can be used. All user interface requirements are isolated via two four-channel optocouplers and a one-channel optocoupler.
The motor speed and current trip points are constantly polled in the main loop. If an over-current is detected, the motor is stopped and the status LEDs blink to indicate a fault. The motor is normally stopped by push-button using braking or soft-stop to return it to its idle state.
The board provides two switch buttons and two potentiometers. There are also headers that provide connections for external I/O, such as garage door trip sensors. The two potentiometers have their transistor in the optocoupler circuitry biased in its amplifying region. The output is therefore approximately linear, since the optocoupler LED does not have a linear I-V curve. Large currents in the 30mA range are consumed for each potentiometer. The digital push buttons and auxiliary inputs are biased to cause an interrupt-on-change (IoC) when either is used. This alleviates the CPU from constantly checking the voltage level on the pins. Whenever an IoC is detected, an ADC reading must be taken to determine which input caused the interrupt.

Conclusion AC induction motors such as used in garage door applications can be driven using an inverter board rather than a traditional capacitor. This allows speed control and soft-start capabilities to be added to the motor at relatively low cost. The inverter board is based around a PIC16F1509 8bit microcontroller from Microchip. ďż microchip technology www.microchip.com
INDUSTRY NEWS Microchip expands Industrial Ethernet switch portfolio with enhanced devices featuring IEEE 1588-2008 precision time protocol and low-power options
Microchip announces the addition of the LAN9353, LAN9354 and LAN9355 Three-Port, 10/100 Industrial Ethernet Switches to its reliable, high-quality, and high-performance portfolio of Ethernet solutions, which includes Ethernet switches, controllers, bridges and PHYs. Featuring the IEEE 1588-2008 Precision Time Protocol (PTP) standard for clock accuracy in the sub-nanosecond range, these highly integrated Ethernet switches offload both synchronisation and communications processing from the host CPU. Developers can also take advantage of advanced features such as Transparent Clocking, which improves system accuracy. Additional features designed to reduce overall system power consumption include Energy Efficient Ethernet (IEEE 802.3az), and Wake On LAN. These switches enable the development of advanced hardware in the rapidly growing Industrial Ethernet market, including automation, motion-control, embedded, automotive, security/surveillance and telecommunications applications. The LAN9353/4/5 10/100 Ethernet switches support widely adopted industry standards, such as MII (Media Independent Interface), RMII (Reduced Media Independent Interface), SMI (Serial Management Interface), Turbo MII, I2C™ and SPI/SQI™ communication interfaces, along with digital I/O. This gives system designers the flexibility to select from a wide range of microcontrollers, Systems-onChip (SoCs) or processors to interface with this new family of switches. Ethernet connectivity has become ubiquitous in communications and networking products. This well-understood technology provides a robust link to ensure reliable communication between devices in a network. To ensure easy installation and network expansion, as well as minimal maintenance, these switches also support 100BASE-FX fibre and copper, along with cable diagnostics that enable system designers and their end-users to determine cable opens, shorts, length to fault and cable length, providing a cost-effective way to extend Ethernet networks over long distances. To enable development with the LAN9353/4/5 ThreePort 10/100 Ethernet Switches, three Microchip evaluation boards were also announced today that support various system architectures. These hardware systems demonstrate how to interface with the switches through basic input/output connections, or with microcontrollers such as the 32-bit PIC32MX family via serial communications.

WIRE-TO-BOARD CONNECTIONS
Minimizing Costs for Wire-to-Board Connections
reutilizing tried and tested technologies
Wire-to-board connections incur high costs when handling large quantities in mass markets. Using the right connection technology, however, such expense can be easily prevented. It's often worth considering the use of tried-and-tested technologies that enable cables and circuit boards to be connected at little cost.
Albert Culetto, Business Development Manager Passive & Electromechanical Components, rutronik elektronische bauelemente Gmbh
Traditional plug connectors consist of two individual elements, and the cable is usually the one that requires more work and therefore more cost, meaning that a two-pin wireto-board solution can rarely be achieved for less than 15 cents. This is why technology is needed that can establish the connection between the circuit board and cable more easily and more cheaply. Thinking outside of the box is allowed. 32

The constantly growing lighting market, for example, has some innovative solutions to offer. Developers in this field require lowcost connection technologies to enable them to remain competitive when connecting millions of units, and such designs can now also be seen in other vertical market segments. It's a similar trend to that seen in the automotive and industrial sectors, and in the field of white goods in electronics pro-
duction â&#x20AC;&#x201C; anywhere, where high unit quantities mean that fast and cost-effective production technologies are needed. Established technologies such as idc (insulation displacement connectors), spring systems or crimping present interesting solutions. They enable any type of cable (single or standard wire) to be cheaply connected to the PCB.
DESIGN
Fewer Work Steps Using IDC IDCs or insulation displacement connectors are suitable for insulated copper cables with multiple wires. IDCs in communication technology with no need for soldering, screwing or insulation stripping have been used since the early 1970s. They enable a gas-tight connection to be established that ensures reliable connection even under rough conditions, and the end product can even be encapsulated. Versions without plastic encapsulation are also available where costs need to be saved. Developers here need to specifically observe the AWG (American wire gauge) system used to prevent wire breakage. In mass production, individual wires are compressed using a bit tool or lever press, which causes all of the wires to make contact through insulation-displacement connectors. The benefit of this is that costly work processes such as wire stripping, pre-soldering and crimping are no longer necessary. The IDC zone can be used up to three times, subject to the parameters specified in the data sheet. IDC is well suited to users who wish to permanently connect sensors, motors, fans or supply cables, as well as other peripheral modules. Spring Systems and Plug-in Contacts The use of spring systems and plug-in contacts in wire-to-board connections help save a lot of time and therefore a lot of money. They are used for terminal blocks, which are formed by punching or bending a single piece, and stand out in particular with their

fast installation. Simplified connections using hooks enable a cable to be connected vertically at costs of less than 5 cents. In production, the contacts can be soldered and assembled during the SMT process. The only additional advance work step is the stripping of the wire insulation. The contact is usually disconnected using a special tool. In vertical systems, you can select from top or bottom entry so that the contact wire sticks out less from the PCB. There are also
Saving Space Using Crimping without Housing Crimping has proven its value as a low-cost connection alternative. For example, the automotive industry uses this technique, where the connection is first approved and then the housing is developed, to make billions of connections each year. Omitting this housing enables considerable costs and lots of space to be saved. This reduces shadowing in lamps in LED applications.
solutions for flat constructions such as solder lugs, which are designed for switches, motors and modules, or Faston terminals for white goods and automotive applications.
The resistance of the connection between the PCB and cable to separation provides high electrical and mechanical reliability. Crimping is mainly used in serial production and is suitable for soldering and assembly in SMT processes. To find the commercially and technically best solution from the range of connection methods, expert advice is critical.

Sensor Instruments: Color measurement of recycled plastic pellets The color of recycled plastic pellets should be measured. It has to be taken into account, that the
position of the pellets behind the inspection glass can vary, thus a big light spot has a certain advan-
tage to get a proper average measurement value. Furthermore, it should be considered, that the ambient temperature around the inspection glass can reach 120°C. For this purpose a color measurement sensor type SPECTRO-3FIO-MSM-ANA-VIS in connec-

Evaluation Boards for SuperSpeed USB-to-FIFO Bridge ICs
Silicon Labs Launches Industry’s Fastest Isolated Current Sense Amplifier
To encourage the widespread utilisation of its highly cost-effective and easy-to-implement next generation USB interfacing technology, FTDI Chip has unveiled a new family of evaluation/development modules. The company’s FT600/1Q USB 3.0 SuperSpeed ICs, which are already in full volume production, are forthwith backed up by the UMFT60XX offering. This module family is made of 4 models, which provide different FIFO bus interfaces and data bit widths. Through these modules operational parameters of FT600/1Q devices can be fully assessed and interfacing with external hardware undertaken, such as FPGA platforms from the industry’s leading suppliers.
Measuring 78.7mm × 60mm, the UMFT600A and UMFT601A each have a high speed mezzanine card (HSMC) interface with 16-bit and 32-bit wide FIFO buses respectively. The UMFT600X and UMFT601X have dimensions of 70mm × 60mm and incorporate field-programmable mezzanine card (FMC) connectors, again with 16-bit and 32-bit wide FIFO buses respectively. The HSMC interface is compatible with most Altera FPGA reference design boards, while the FMC connector delivers the same functionality in relation to Xilinx boards. Fully compatible with USB 3.0 SuperSpeed (5Gbits/s), USB 2.0 High Speed (480Mbits/s) and USB 2.0 Full Speed (12Mbits/s) data transfer, the UMFT60xx modules support 2 parallel slave FIFO bus protocols with an achievable data burst rate of around 400MBytes/s. The multi-channel FIFO mode can handle up to 4 logic channels. It is complemented by the 245 synchronous FIFO mode, which is optimised for more straightforward operation. “We recognized early on that USB 3.0 system designs that are reliant on programmable logic, rather than MCU technology, are going to have a multitude of important benefits to the embedded engineering fraternity. They will allow bill-of-materials costs to be kept under control and the writing/compiling of masses of C code to be avoided,” states fred dart, CEO and founder of FTDI Chip. “As a result we have worked closely with the most prominent companies in the programmable sector to promote this more technologically and financial efficient method of implementing USB 3.0. The new modules we have introduced are designed such that they can plug into most FPGA development platforms supplied by vendors such as Xilinx or Altera.” For more information, visit: www.ftdichip.com/ft60x FTDI ChIP

Thermocouples are one of the most ubiquitous temperaturemeasurement devices, due to their robustness and accuracy in harsh, hightemperature environments, and their ability to measure temperature over an extremely wide range. The MCP9600 simplifies thermocouple designs by integrating a number of discrete devices into one chip, which also lowers board area, cost and power consumption. Thermocouples are widely used to measure temperature by the designers of industrial, consumer, automotive/ aerospace and petrochemical applications, among others. The MCP9600 provides them with the world’s first plug-and-play solution for creating
thermocouple-based designs, because it eliminates the design expertise required for a discrete implementation,
such as firmware development using an MCU’s maths engine. Designers no longer have to create precision instrumentation circuitry to accurately measure a thermocouple’s microvolt-level signals, nor do they have to design ADC circuitry for precise temperature calculations. With the MCP9600’s integrated cold-junction compensation, calculating the “Hot” junction temperature of a thermocouple does not necessitate thermal design expertise to precisely measure the reference temperature of the thermocouple’s “Cold” junction.

Power Integrations Delivers Industry’s First Charger Interface IC Compatible with Qualcomm’s Quick Charge 3.0 Technology Power Integrations announced its newest member of the ChiPhy™ charger-interface IC family CHY103D, the first IC for off-line AC-DC chargers compatible with the Quick Charge (QC) 3.0 protocol from Qualcomm Technologies, Inc., a subsidiary of Qualcomm Inc.
Used alongside Power Integrations’ InnoSwitch™ AC-DC switcher ICs, the CHY103D device incorporates all of the functions needed to support QC 3.0. The QC 3.0 protocol implemented in the CHY103D device substantially reduces losses in the smart mobile device handset during rapid charging. This permits system designers to choose to charge handsets faster or reduce phone touchtemperature during charging, and enhances the efficiency of the charging process. The IC improves charging efficiency and reduces heat dissipation by enabling voltage changes in 200 mV increments instead of the larger steps (e.g., from 5 volts to 9 or 12 volts) employed in many current rapid-charging designs. This technique allows the mobile device to optimize the supply voltage from the offline charger, minimizing losses in the phone’s internal charge-management system. CHY103D includes a wealth of protection features including Adaptive Output Overvoltage Protection (AOVP), which prevents the output from exceeding 120% of the set output voltage, Output Soft Short-circuit Protection (OSSP), which detects partial shorts and stops power delivery to prevent overheating of cable and connector, and a Remote Shutdown Protection (RESP) feature which enables the powered device to shut the adapter off remotely if a fault is detected. The CHY103D device itself consumes less than 1 mW at 5 V output; in combination with highly efficient InnoSwitch devices, this low power consumption aids designers in complying with stringent efficiency requirements for chargers, such as the upcoming revision to U.S. federal standards for external power supplies.

Toshiba Launches Ultra-low Drop-out 500mA LDO Regulator ICs Toshiba Electronics Europe has launched a new series of 500mA LDO Regulator ICs that achieve the industry’s lowest-in-class drop-out voltages. The devices are ideal for power management applications in smartphones, tablets and other battery operated devices including wearables. To increase efficiency of these LDOs special attention is put on minimizing the drop-out voltage at high output current and low output voltage operation. The new TCR5AM series achieve an ultra-low dropout voltage by adopting a secondary bias voltage supply (VBAT) as a reference voltage. Applying VBAT = 3.3V enables a 0.6V output voltage operation with typical dropout voltages as low as 0.090V (@ IOUT = 300mA) and 0.150V (@ IOUT = 500mA). This performance makes the
TCR5AM series suitable for high-current loads (such as RF or camera circuits) in battery operated designs. In addition to the excellent drop-out performance the TCR5AM series includes integrated protection fea-
tures like over-current and over-temperature protection as well as undervoltage lock-out and auto output discharge functions. TOShIBA ELECTRONICS EUROPE www.toshiba.semicon-storage.com

It is possible that you already have to do with IoT, without even realising it.
What iot means? This concept of Internet of Things (IoT) is not so from the present but more something evolved from the past, some would argue that the discussions started in early 90s. All started with the idea of mainstreaming identification chips (RFID) in and with all items we interact with in our day-by-day life. Actual, IoT refers to devices with an advanced connectivity, systems and services that interact with one another and cover a variety of protocols, domains and applications. In short terms, devices will (and are) communicate with each other and even will be able to make decisions based on the feedback received from other equipment.
