Hi All,

   Board Name : EK-TM4C1294XL.

     I stuck up with writing Alphanumeric LCD(8bit) Interface coding. Any sample code available.

Best Regards,

    Hi Murali,

    TI-RTOS does not have an example/driver for LCDs, but after a small e2e search I found these posts (link or link) where a customers have done the same with a Stellaris Launchpad.  I believe, with little effort, you can port the code to use the TI-RTOS GPIO driver (maybe even create an TI-RTOS based LCD driver of your own!!).

    Hope this helps,

    7144.Board.hHi Emmanuel0820.gpiointerrupt.zip

    Board Name :- EX-TM4C1296XL

    TI-RTOS Ver. :- 2_10_01_38

    Thank You Emmanuel..  I try to Implement the same LCD code in the TI-RTOS environment.  Now I picked up gpiointerrupt project code and try to modified, I start testing DATA lines , while building  the code there’s no errors  but run in the debug mode, auto exit while bellow given line of instruction

    GPIO_write(LCD_Data0|LCD_Data1|LCD_Data2|LCD_Data3|LCD_Data4|LCD_Data5|LCD_Data6|LCD_Data7, 0x02);

    I have attached modified .C & .H files for Your reference.

    One more question how to configure GPIO bus (8 bits)   IN or OUT mode while executing the program ..?

    Best Regards,
