Connect ili9341 LCD on zero 2 pro

binchiling100 · July 2, 2025, 2:46pm

I want to use a ili9341 spi screen with the radxa zero 2 pro at high framerate. I considered the fpcb-ili9341 driver but it wasnt compatible. Im currently running armbian. Also im planning to use the screen as a main screen so i want to copy the framebuffers onto the screen.

there are two examples for spi lcd, maybe you can refer to.
