A small, stm32f072 devboard in the pico form factor! I've played around with the RP2040 and various ESP32 chips for the past few years, but I wanted to try something different. The STM32 series of microcontrollers are very popular especially for low power usage, and I wanted to try using one myself. There's also less abstraction (imo-at least compared to MicroPython) when writing code for the STM32 and I think it'd be a great chance for me to practice my rust a little.
- Clone and open the firmware/ folder (or clone the firmware repo directly: ShuchirJ/stm32-blinky)
- Install the Rust toolchain and the thumbv6m-none-eabi target (
rustup target add thumbv6m-none-eabi)
Note
This step assumes you are connected via SWD debugger. If you want to flash the firmware using USB, install rs-dfu (or similar) and skip to step 4.
- Build and flash the firmware using
cargo run --release
Flashing via DFU:
cargo build --releasecargo objcopy --release --bin stm32-blinky -- -O binary target/thumbv6m-none-eabi/release/stm32-blinky.binrdfu write --start-address 0x08000000 target/thumbv6m-none-eabi/release/stm32-blinky.bin(or similar command for an alternative dfu utility)
The board follows a SIG-GND-PWR-SIG stackup.
SIG (1):
GND (2):
PWR (3):
SIG (4):
