Building

Metro M4

cd metro-m4-examples
cargo build --release --examples --target=thumbv7em-none-eabihf

STM32F103 Blue Pill

cd blue-pill-examples
cargo build --release --examples --target=thumbv7m-none-eabi

STM32F411CE Black Pill

Build with:

cd black-pill-examples
cargo build --release --example draw_ferris

create a bin file and flash in DFU-Mode. To get to the DFU-Mode hold the BOOT0 button while pressing the NRST button. To flash use:

cd black-pill-examples
cargo objcopy  --release --example draw_ferris -- -O binary draw_ferris.bin
sudo dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D draw_ferris.bin
