Having issues setting up for Pimoroni Pico Display

[AustinSaintAubin]

I an trying to make a hardware_setup.py for the Pimoroni Pico Display, here is an example w/ display. Can someone point me in the right direction/help me please.

The closest supported display is probably this with this setup file.

There are two things you need to find out:

1. Does the display use an ST7789 controller?
2. If so, you need to check the Pico pins used to connect to the controller.

Then edit the above setup file to suit, rename to hardware_setup.py and put in the root. Copy paste the quick hardware check in the docs. If that works, you might like to submit your setup file and I will add the display to the docs.

Thanks for the help, was able to get it working with the code below, using the quick hardware check code.

Thanks for that. I have pushed the update, also updated DISPLAYS.md.
