#### Natively/without VS Code Dev Containers
1. Install avr-gcc >= v13.1, binutils >= v2.39, cmake >= v3.24
2. Configure cmake in repo with `cmake -B build`
2. Configure cmake with a hardware-target preset, e.g. `cmake --preset attiny3216-debug-usb0`
(the preset selects the AVR cross-compile toolchain; `cmake --list-presets` shows the rest)
- Trigger builds with `cmake --build build`
3. Start developing!
### Flashing
The CMake target `upload_mockingboard` uses the AVRDude utility using the "serialupdi" programmer type. I use a [USB => Serial converter](https://www.adafruit.com/product/5335) with the Rx and Tx lines connected, using one of the options described [by SpenceKonde here](https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md).
