Hi Ive been trying to port a display driver ili9341 on STM32H7A3zi-q for a long time but I cant get it to working. I'd be grateful if someone already did it and could share the driver. Cheers, Dan

I'd suggest to start from:

https://github.com/prenticedavid/MCUFRIEND_kbv

I adapted code for nucleo-H743Zi2, there is a chance software would run on H7A3zi as well.

Thanks, Ive actually managed to port the display, unfortunately the touch screen doesn't work. I ve checked SPI and ehrn I dont connect miso/mosi external interrupt works, but once I connect it, it triggers without touching. 0693W00000NqVHEQA3.png0693W00000NqVH9QAN.png0693W00000NqV2HQAV.png0693W00000NqVH4QAN.png

What is the hardware? MCUFriend arduino shields based on ILI9341/ 9486 /etc they sell on amazon has R-esistive touch sensor. No spi required. just GPIO pins to drive R-Matrix and an ADC to decode X-Y.
