Rust on the Ferris Sweep

a year ago

RMK is a keyboard firmware written in Rust, chosen for a Ferris Sweep keyboard.
QMK, a C-based firmware, is mature but complex for custom keyboard designs.
RMK lacks pre-made configurations, requiring users to define pin mappings and keymaps manually.
Setting up RMK involves using `rmkit` to generate a template and configuring `keyboard.toml`.
Pin mappings were derived from the PCB design due to incompatibility with QMK's mappings.
Half-duplex UART communication was configured using RP2040's PIO feature, requiring a git version of RMK.
A `vial.json` file was created for VIAL software compatibility, involving layout adjustments.
Initial flashing issues were resolved by lowering the baud rate due to insufficient pull-up resistors.
RMK is functional but lacks some advanced features like display support and per-key RGB.
RMK is recommended for those familiar with firmware configuration and interested in Rust.
