Firmware

An implementation of SlimeVR firmware, built in Rust. Uses embedded-hal instead of Arduino.

Target Hardware

For now, we are only focused on the ESP32 platform, specifically the ESP32-C3. This is because the ESP32-C3 is a RISC-V architecture, which is natively supported by rust without needing a fork of llvm.

Furthermore, the ESP32-C3 supports bluetooth in additon to wifi, has hardware I2C, built-in USB Serial and JTAG debugging.

The ESP32-C3 also claims to have a stronger wifi signal, which will help with lag.
