Sensor library in Rust designed for use with SignalK and the Sailor Hat ESP32. Built with heavy inspiration from SensESP. While this library will strive to eventually reach feature parity with the C SensESP implementation, it will not necessarily follow the same patterns.

Lots of starter information can be found in The Rust on ESP Book. You will need to install a toolchain for the xtensa-esp32-none-elf target. This is a std project, not no-std, so the full standard library is at your disposal.

cargo install espup
espup install

cargo install espflash
cargo install cargo-espflash

To expose the serial port to WSL, usbipd must be used to forward the port. See this guide. There is also a vscode extension, USBIP Connect.

You may also need to deal with permissions on the device, which is likely /dev/ttyUSB0 after attaching with usbipd. This can be accomplished by using udev to add the device to the dialout group, adding the user to this group as well, and setting permissions to 660.

See: (Enabling udev)[microsoft/WSL#8502] (Adding udev rule for virtual USB device)[https://askubuntu.com/questions/1048870/permission-denied-to-non-root-user-for-usb-device]

Build all targets: cargo build

Run the example on an ESP32: cargo run --bin example

Run the I2C scanner: cargo run --bin scanner

Eventually, cargo test will also do something. Today is not that day.
