Adafruit pitft 3.5 (480x320) #536

Hi, I am trying to get this display to work in full resolution with the fbtft_device module, but I am having no luck. I tried these options:

  1. Use fbtft_device name=adafruit28
  2. Use fbtft_device name=pitft Both of them have the same result. There is a part of the screen that I can draw onto and the rest just stays as random pixels. What should I do to get it working on full resolution? Also it may be worth mentioning, that I am on a Raspberry Pi zero w running Arch Linux ARM.

Edit: The adafruit28 option does not do anything.

@satcom886 take a look at https://github.com/notro/fbtft/wiki/LCD-Shields

So even if I do not need the touch functionality, I have to stick with the adafruit kernel (or compile my own), right?

If you're on a Raspberry Pi then you can use this DT overlay: pitft35-resistive
