This is the most simple example embedded application for ATmega169 written with Rust.

It is used the API from crate avr-device. At the moment of writing there is no support of ATmega169 devices. The support is available with the repository kolbma/avr-device.

Run the provided ./cargo.sh build --release.

Convert the elf file to an ihex file with:
avr-objcopy -S -j .text -j .data -O ihex target/avr-unknown-gnu-atmega169/release/blink-atmega169.elf target/avr-unknown-gnu-atmega169/release/blink-atmega169.hex

Flash your ATmega169 with an avrdude command like:
avrdude -p m169 -c avrispmkII -P /dev/ttyUSB0 -U target/avr-unknown-gnu-atmega169/release/blink-atmega169.hex

Connect an LED with a restistor to VCC and PORTB PB7.
Power on your device and see the LED blinking.
