Computer mouse from scratch.
This repository serves as an appendix to my master thesis.
New features and bugfixes won't be added to this repository. I plan on separating different parts of the repository into a bigger project sometime in the future. If you come across this repository before I do that, feel free to open an issue here.
This repository contains blueprints for building a computer mouse.
The pcb is made using Kicad with components from LCSC, to support assembly service from JLCPCB.
Housing (or case) is designed in Fusion360 and is meant to be 3D printed using SLS (also available on JLCPCB).
First iteration of the firmware was written in C using libopencm3 library. Due to a lack of higher level ergonomics and support for board specific abstractions, it was later re-written in Rust.
The new version of firmware is split into 2 parts:
- Drivers for various components (e.g. sensor, encoder...) are exposed as a library using embedded-hal traits as abstraction. It is intended to be portable across different hardware and possibly used in other mouse-related projects.
- Board specific implementation is essentially just glue-code between hardware specifics and modules from the forementioned library.
