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

For now, we are only focused on the ESP32 platform, specifically the ESP32-C3, and the NRF52840. We think these chips are the best platforms to develop the firmware on.
- Super cheap chip ($1.80 for a module).
- Supports both WiFi and Bluetooth.
- USB serial without a uart converter. Keeps PCB costs low.
- Supports JTAG debugging without needing a hardware probe! This enables crazy stuff like logging over RTT which is much more efficient than serial.
- RISC-V architecture means it's well supported by LLVM, unlike the ESP32/8266.
- Hardware I2C instead of bit banging like on the esp8266.
- Unfortunately it's not as power efficient as the nrf52840.
- NOT a cheap chip, like $6 for a module.
- Seems like it's 6-10x more power efficient than esp32c3. This is the main selling point, we can make tiny trackers.
- Bluetooth only, although we can do some proprietary protocols.
- Has amazing async rust support.
- Has built in USB support, not just as serial but full USB.
- Supports a debugger but only with a hardware probe.
We likely easily can support most nrf52 and esp32 family chips. Right now the ones we officially have added support for are:
- esp32c3
- esp32
- nrf52840
- nrf52832
For the initial minimal viable version of the firmware, we are targetting these imus, but feel free to add support for more, if you can test and verify the imu.
- MPU6050
- MPU9250 (6dof)
- BMI160
- LSM6DS3
- BNO08X
We are trying to improve our documentation, feel free to open an issue or a PR if something is missing/unclear.
