Polybius

Keyboard firmware experiments on the bleeding edge of Rust's const-eval.

NOTE: This crate is not being maintained anymore. I've encountered difficulties porting other architectures and keyboards (especially split) to this design, and so instead of trying to port everything to this and adapt it, I have decided to move on.

I will eventually buiild a new framework, but first, I will be building a lot of firmwares from scratch. Abstractions will come later.

Features

• Modular design. Polybius is intended to be a simple "glue" library, the bridge between keyboard support packages and user-defined keymaps. Both of these can and should be implemented as separate crates.

• Type-checked keymaps and matrix I/O. Uses Rust's powerful type system and compile-time evaluation to validate that:

  • The user's keymap matches the layout specified by the hardware.
  • The correct number of I/O for rows and columns is provided by the hardware support package.
  • The I/O direction of rows and columns matches the diode configuration.

Featured Crates

• my_keyboards by Adam Gausmann - Examples of end-user code using Polybius; keymaps for the keyboards I own.
