Use Raspberry Pi Pico 2 Make your Own Keyboard

[OpenELAB]

Story
In our work hours, we always need to use shortcut keys. Almost all keyboards have less than 4 custom keys, so I have always wanted to make a keyboard with custom shortcut keys.
I recently received a new Raspberry Pi product. Right, it's a Raspberry Pi Pico 2, so I think it's time to make it. Let's do it now.

Hardware
1 x Raspberry Pi Pico 2
12 x Cherry MX Style Keys
13 x Wire
1 x M3 Screws Kit

You'll find space for the Pico 2 and wiring below. The USB port on the Pico 2 will be accessible from the hole in the back of the enclosure, so you can connect it to your computer. You can insert the cover from the bottom of the keyboard and secure it with two screws later on. This way, you won't see the junction between the enclosure and the cover.


Electronics
Arduino Nano

First of all, I used Arduino Nano to make a keyboard, but that makes me sad. When I write code already, everything looks well.
But......
Unfortunately, the Arduino IDE can't use USB-HID.
The first version failed. You guys don't need to consider nano anymore.

And I received a Raspberry Pi Pico 2. That made me change my mind. This time I tested the simple code first.
It worked, that's very nice. Let's move on.

Raspberry Pi Pico 2

Install CircuitPython into Pico 2.
If you don't know how to install CircuitPython, look at this:
1. Install Mu Editor
Download Mu Editor from codewith.mu and follow the installation instructions.
Upon first launch, select "CircuitPython" mode.
2. Install CircuitPython on Pico 2
Download the latest CircuitPython 9.2.0-beta.0 from CircuitPython.org.
Hold the BOOTSEL button on the Pico 2 while connecting it to your computer via USB.
Drag and drop the .UF2 file to the Pico 2 drive.
3. Start Coding
Once installed, open Mu and begin writing code. It’s that easy!

Then open Mu IDE, choose CircuitPython, connect Pico 2, and choose the right port.

Code
Make sure your pico 2 gpio connects the keys.
keys = [
digitalio.DigitalInOut(board.GP0),
]
Define the right gpio in this part
keymap = [
[Keycode.CONTROL, Keycode.C], # Ctrl+C
]
Define the keys setting you wanted, like'Keycode.CONTROL, Keycode.C' means 'Ctrl+C', it's a copy key set.


Summary
That's all the parts for this simple keyboard. If you have some good ideas, contact us please, like putting some LEDs in this keyboard.
Anyway, have fun with your project. Hope we can find more and more funny things.
