ILI9225 driver?

anteater · February 28, 2026, 11:38pm

Hello,

Is there already / is there any recommended or easy way of making a driver for ILI9225 LCD touch screen with the Daisy?

I found one for the ILI9341, but am not sure if there is one for the 9225 or if changing this in same would be easy/possible. Thank you!
