OVERVIEW Libraries and system functions are available to make programming the GLCD + RTC Combo Module a whole lot easier. The RTC Library is one such example, calling the subroutines and functions from the library automatically handle the read and write communications between the FI Microcontroller and the module via I2C.
The FI RTC (Real Time Clock) Module Library The FI RTC is located at the back of the GLCD + RTC Combo Module. Please refer to the PINOUTs for pin specification. You can add the RTC library to your project by selecting Project > Add Module and selecting LIB_RTC. Note that the Library Module is now a part of your project. LIB_RTC Contains 4 Routines; • RTC_READ_TIME •
• •
RTC_READ_TIME_EX RTC_READ_DATE RTC_SET_TIME_AND_DATE
To get the current time, use RTC_READ_TIME(HRS, MIN, SEC). The time in Hours, Minutes and Seconds will be returned in the HRS, MIN, SEC variable. You can display it in the debug window using the instruction Debug.Print.
CODE: Dim SEC, MIN, HRS As Integer Public Sub Main() RTC_READ_TIME(HRS, MIN, SEC) Debug.Print "DATE:"; CStr(HRS); ":"; CStr(MIN); ":"; CStr(SEC); " "; End Sub
For precise timing operations, you can use RTC_READ_TIME_EX(HRS, MIN, SEC, T10, T100) to get precision to a hundredth of a second. To get the current date, use RTC_READ_DATE(DAY, MTH, YRS) to return the date.

To set the date and time for the RTC to start keeping track of, you can make use of the function specifying the hours, minutes, year, and month; RTC_SET_TIME_AND_DATE(HRS, MIN, YEARDATE, MTH). Note that you cannot set the seconds. Variables mentioned must be declared by the user.
CODE: Dim T10, T100, SEC, MIN, HRS, DAY, MTH, YEAR As Integer
Programming the GLCD Interacting with the GLCD is a very versatile affair; you can store images to dump into the screen using an External EEPROM, or the FICE SD Card, or programmatically plot the image to the screen pixel by pixel. The FlamingICE Operating System, aka the FI Firmware onboard the FI chip contains system commands to write to the GLCD. The full coverage can be obtained by referring to the FIDE System Library under OS.GLCD. You can also refer to the online tutorial on how to load an image to the GLCD using an external EEPROM. Writing text to the screen is as simple as stating the string you want on the screen by using the OS.GLCD.Print command.
Example: ‘The following program initializes the GLCD, fills the GLCD with the ‘colour white, sets the position of the cursor to the x,y point (5,10), ‘sets the font size to large, and prints the lines at the cursor ‘position. OS.GLCD.Init() OS.GLCD.Fill(255) OS.GLCD.SetPosition(5, 10) OS.GLCD.FontSize(1) OS.GLCD.Print "TEST 1" OS.GLCD.Print "Test 2"
