Pre-release

This release is a pre-release and may not be stable for production use.

pymcu-avr

AVR (ATmega/ATtiny) backend for the PyMCU compiler. Free and open source.

Bundles the pymcuc-avr AOT binary that reads .mir IR files and emits AVR assembly, then drives the AVR toolchain to produce a flashable Intel HEX file.

Pipeline

pymcuc --emit-ir        →  firmware.mir    (target-agnostic IR)
pymcuc-avr (this pkg)   →  firmware.asm    (AVR assembly)
avr-as / avra           →  firmware.hex    (Intel HEX)

Installation

pip install pymcu-avr

The AVR toolchain (avr-gcc, avr-as, avr-objcopy) is sourced (in order) from the pymcu-avr-toolchain wheel cache, common system install paths, or PATH. A system avr-gcc also works with no extra package:

# macOS
brew tap osx-cross/avr && brew install avr-gcc

# Debian/Ubuntu
apt install gcc-avr binutils-avr avr-libc

Supported targets

Families: atmega, attiny, at90, atxmega.
Examples: ATmega328P, ATmega2560, ATmega32U4, ATtiny85.
