Pico Environment Sensor
This firmware, written in Rust using embedded-hal (rp235x-hal), is designed for the Raspberry Pi Pico 2 W platform using the RP2350 microcontroller. Its application is an environment-sensing device which can measure CO2 concentration in the atmosphere, ambient temperature and humidity.
Building
Prerequisites
- Rust compiler & cargo package manager: https://www.rust-lang.org/
- RPi Pico SDK: https://github.com/raspberrypi/pico-sdk
- RPi picotool: https://github.com/raspberrypi/picotool
- ARM bare metal compiler toolchain
arm-none-eabi-gcc(&arm-none-eabi-newlib) on Arch Linux, your system may have different package names
Environment configuration
This build system assumes the environment variables: PICO_BOARD, PICO_PLATFORM & PICO_SDK_PATH are set. picotool should also be available in the PATH.
The env-vars.sh script sets these values to pico2_w, rp2350-arm-s and my personal Pico SDK path, respectively.
Compiling & running
cargo build(orcargo build --release)
If you wish to run the binary on your Pico (connected in BOOTSEL mode):
cargo run(orcargo run --release)
