This is the firmware, in Rust, for my Dactyl Manuform: Opposable Thumbs Edition (or DMOTE for short).
I used a STM32F103C8 MCU, wired into the two halfs of the keyboard as the controller. The tooling within assumes that you will flash this controller with a DAP42 probe attached.
This firmware has some unusual features:
- Scanning of the key matrix is done entirely with DMA, without any interaction with the firmware.
- "Qick-Draw" debouncing, minimizing key press latency, even when the debounce time is set very long.
This repo contains some vendored dependencies. In particular:
| Dependency | Reason |
|---|---|
| stm32f1 | DMA to/from registers needs the .ptr() method on registers |
| stm32f1xx-hal | Compatibility with vendored stm32f1 dep |
I'm likely to un-vendor stm32f1 and stm32f1xx-hal when versions of them become available that meet my needs.
