https:\/\/www.waveshare.com\/wiki\/Pico-RGB-LED<\/a> is horribly broken and this was hard to Google so hopefully this helps *you* or future-me.<\/p>\n\n\n\n

I did not manage to put the display directly on top of the Pico as a hat. Also my display’s board has its pins numbered and labelled mirrored when comparing to the official pin out. FFS…!?<\/p>\n\n\n\n

\n\n\n\n

Install pico-sdk<\/code> and thonny<\/code> from AUR.<\/p>\n\n\n\n

$ sudo usermod -a -G uucp $USER<\/code><\/p>\n\n\n\n

Reboot.<\/p>\n\n\n\n

Make sure you aren’t full of static electricity. Hold the BOOTSEL button on your PI and connect it to your PC using a USB cable.<\/p>\n\n\n\n

It should appear as storage device.<\/p>\n\n\n\n

Start Thonny, select “Micropython (Raspberry Pi Pico)” as interpreter and use its “Install or update MicroPython” option. This does that “copy some RPI_PICO-20231005-v1.21.0.uf2 file to your Pico in mass storage mode” step for you.<\/p>\n\n\n\n

The Thonny shell should say something like:<\/p>\n\n\n\n

MicroPython v1.21.0 on 2023-10-06; Raspberry Pi Pico with RP2040\nType \"help()\" for more information.\n>>><\/code><\/pre>\n\n\n\n
Enter the following code in your Thonny shell (via<\/a>):<\/p>\n\n\n\n
from machine import Pin\nled = Pin(25, Pin.OUT)\nled.on()<\/code><\/pre>\n\n\n\n
The Pico’s green LED should glow now. Use led.off()<\/code> to turn it off again.<\/p>\n\n\n\n
Unplug your Pico. Make sure you aren’t full of static electricity.<\/p>\n\n\n\n
Connect your Pico and Waveshare Pico-RGB-LED like described in https:\/\/thepihut.com\/blogs\/raspberry-pi-tutorials\/how-to-use-the-waveshare-rgb-full-colour-led-matrix-panel-for-raspberry-pi-pico-part-1<\/a>:<\/p>\n\n\n\n
On the display there are four pins in a length-wise direction on the board.<\/p>\n\n\n\n
