Raspberry Pi Pico Display Pride - M0YNG.uk

Code

I couldn't resist the raspberry pi pico any longer, and I also got a pico display to do with it. This is a pico sized hat that sits directly onto the pico and provides a nice full colour screen, RGB LED, and 4 buttons.

After playing with the demo code I wanted to try something myself, so I thought I'd try making a name badge of sorts, and using the pride flag as the background. Then I wanted to use the buttons, so made each button show a different flag. The LED also changes, trying to show some key colours from the flag.

It can show:

Pride rainbow
Trans
Intersex
Bi

In this quick demo I've made it run through the flags automatically.
