Honored ContributorHi,
We are trying to use this *******g LT24 screen with the Nios2 (on the DE0) and nothing works. We used the Painter Demo and added a custom SPI in QSys. Our project compile well in Quartus and in Eclipse but the SOPC keeps crashing in the painter demo. I used the debugger included in Eclipse to find out what's buggy but the system crash at various random locations... In most case the CPU crash in the touch_enable_penirq() function when it sends data on the Bus. Sometimes it passes through and goes to the gui function. The gui doesn't work (the screen is always white) but we get the console outputs related to the position of the touch. So I think the screen is very buggy even in theire implementation in the demo painter... Also, our program worked once (after a lot of tries) but the image was flipped (mirror effect). Since then, it has always been white... Did you find a solution to your problems ? I'm really interrested in some tips to try to debug this screen... Thanks a lot ! Gp2mv3
