RGB parallel interface on ST7796

[Da_QSM]

Hi

 

 I'm trying to drive a screen through a parallel interface. The screen has the ST7796 driver. I was able to initialize it, but it only displays noise. When data is sent through the parallel interface, it doesn't display. Do you know the necessary LTDC configuration? Or if special hardware is needed to connect the screen? I'm currently connecting the screen to the H7A3ZI core card with cables.

Hello @Da_QSM and welcome to the community;

Could you please give more details about the LTDC configuration.

I recommend you to take a look at AN4861 precisely section "7 LTDC application examples" and get inspired to configure the  ST7796.

I hope this help you.

Thank you.
