firmware: The main firmware repository. This will generate the firmware binary.common: Common code like configuration management in EEPROM.cli-utils: Utilities likeconfig-flasherA tool that can write config EEPROM based on a config TOML file.
We use the following timers:
LPTIM: Used as aMonotonicimplementation for the RTIC scheduling systemTIM7: Used as a blocking delay provider for the device drivers
Requires Rust stable, as specified in the rust-toolchain file.
# Install dependencies
sudo pacman -S arm-none-eabi-binutils arm-none-eabi-gdb
# For debugging we need JLinkGDBServer
yay jlink
# Install target
rustup target add thumbv6m-none-eabiTo build the firmware:
cargo build --release
In one terminal:
JLinkGDBServer -speed 4000 -if SWD -device STM32L071KB -port 3333
In another terminal:
cargo run
Use cargo-embed (0.8+):
cargo embed flash --release
To reset the target without flashing (requires cargo-embed 0.9+):
cargo embed reset
To enable more verbose debug logging (e.g. with conversion of raw temperature
data) as well as some debug assertions, enable the dev features
cargo embed flash --release --features dev
Unit tests run on the host system, so we need to specify the target accordingly:
cargo test --target x86_64-unknown-linux-gnu --tests
cargo test --target x86_64-unknown-linux-gnu --tests --features dev
First, prepare a config file like this:
# config.toml
version = 1
devaddr = "00000000"
nwkskey = "11111111111111111111111111111111"
appskey = "22222222222222222222222222222222"
wakeup_interval_seconds = 900
nth_temp_humi = 1
nth_voltage = 4Then flash it to the attached board:
cargo run --bin config-flasher -- --config config.toml
