Ergonomic, split and other weird keyboards
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

I took a WaveShare RP2040-Touch-LCD-1.28and made a program to use it as a touchscreen. This is still very much in the beta phase but the proof of concept works. Here’s my GitHub repo for it.
I’m planning on integrating it into my next split near the thumb cluster.
Very cool indeed! I'd like to see the keyboard integration, once it's ready. Are there enough free pins on this module to handle the GPIOs for a keyboard matrix?
There are 6 GPIO available. So maybe a macro Pad… but my idea is do embed it in The case but still have a separate usb cable to it. You can also display things on the screen if you’d like. It has a RTC and a battery management circuit so you could make it into a clock, or use the GPIO to speak with your keyboard to send keystrokes data via serial…
I guess if the available pins support i2c you could hook it up to a gpio expander
Yes. It does I2C. It’s also a pi Pico core so dual core. So you could use a separate core to drive the screen independently from the keyboard to keep them fast.
Edit: actually the i2C is not exposed on the pins, but you should be able to use the BitBang_I2C library to expose them on any pair of GPIO pins. I’ll try it out and report back.
Edit2: actually, no need for that library you can set virtual I2C to any pins I tried it with another project on the same board.
