+Besides the original hardware this firmware can also be compiled for ATmega328P based 16 MHz Arduino Uno R3, Nano and Pro Mini.

## Toolchain
|
|
|
|
|
|
The registry toolchain `toolchain-atmelavr@1.70300.191015` is an x86_64 build and does not run on
|
|
|
Apple Silicon without Rosetta. `platformio.ini` therefore points `toolchain-atmelavr` at
|
|
|
`tools/toolchain-native`, which symlinks `/opt/homebrew/bin/avr-*` (avr-gcc 9.5, avr-libc 2.1.0).
|
|
|
On an Intel or Rosetta host replace that line with `toolchain-atmelavr@1.70300.191015`.
|
|
|
-The framework is pinned to `framework-arduino-avr@5.4.0` (Arduino core 1.8.8); the original used an
|
|
|
-older core, which phase 0 still has to compare in simulation.
