PocketBeagle Display options

by ocram on Mon Nov 11, 2019 10:58 am

I have looked around for this information but I am having little luck finding a definitive answer. Is there a frame buffer driver for the PocketBeagle that can push X11 display data over the SPI bus? I am writing a python application using GTK and of course it can display over the SSH connection by forwarding the display to my computer. But I am hoping to run this application directly on the PB and have a local display. I've seen some information about the PB used for a mini arcade so it seems to me this is possible in some manner. If it is, do you have an example you can point me to?

Thanks!

You should be able to use the fbtft drivers with X11:

Which display do you have?

There are different drivers for different controllers.

Cool! This is encouraging news. I have not ordered it yet, I am developing the GUI on the computer for now but ideally the 3.5" tft is what I want in my implementation: https://www.adafruit.com/product/2050

Hopefully the tftfb library works with it :).
