CCS/SW-EK-LM4F232: TIVA C graphics library not working

LEUL G.
Prodigy 20 points
Part Number: SW-EK-LM4F232
Other Parts Discussed in Thread: EK-TM4C1294XL, BOOSTXL-K350QVG-S1

Tool/software: Code Composer Studio

Hello, 

I was using stellaris LM4F to work on TFT colour display touch pannel attached on easymxpro V7.

I found a code example for a simple rectangular touch push button from TM4C123G_LaunchPad workshop to display a button on touch screen and control a LED on the Board.

The problem is the  screen gets blank WHITE if the TouchScreenInit() function is initialized in the mains. 

If i didnt initialize or call TouchScreenInit() function the display will get properly initialized and displays the buttons but 

pressing or touching  the button on the screen wont control the LED. below is the snippt of the touch screen, and the program associated with it. any help?

    The LM4F232 part is no longer sold by TI and support for that part was removed from the latest version of TivaWare. That said, it was a different part from the TM4C123 so using that example is likely to cause problems. I suggest you look at using the EK-TM4C1294XL Launchpad with the Kentac BoosterPack BOOSTXL-K350QVG-S1 instead.
