Circuitpython Raspberry Pi Pico USB HID Keyboard (the smallest keyboard, part 2)

In this video, we walk through the Circuitpython + Raspberry Pi Pico USB HID keyboard code (matrix decoding, sending keypresses, etc.)

Thank you! I needed a little 8 keys keypad for work. It's first time I trying RP2040 and python, so it was hard forme to understand how this shoud work. I started with arduino uno, wich doesn't support HID easely, so I bought RP and I tried everything, I watched alot of videos, tried alot of code, C++ too and nothing worked. I spent 4 days looking for solution and only your's code is working!
THANK YOU! You are awesome!

Love it!
Love the concept and simple implication of poling. Never thought about the CTRL, shift, etc. Keys. Keep up the good work! :)

Also worth considering PRK, have had good success with early versions of that which allow booting up solely as a USB keybaord, so more useful for odd Linux systems that don’t like the extra stuff that enumerates!

Amazing work by the way :-)

So we finished making our tiny keyboard! It was heavily inspired by yours. It is designed to stack directly onto a Raspberry pi zero. I was wondering if you wanted to see one? I'll be happy to send you one if you'd be willing to share with me the code for how to use it on Python. I only know Arduino coding so far...

Thanks very much for the explanation. I am working on a similar project. Are there any other steps needed to make this a functional keyboard for a raspberry pi? Basically we want it to be THE keyboard, while using the raspbian OS.

Great video man, I'm doing something similar with a pico, a USB HID 4 x 4 matrix keypad, is there an example I can refer to? it's kinda hard with little to zero coding experience.
