toolchain-avr-gcc

toolchain-avr-gcc is a CMake toolchain for cross compiling for the Microchip AVR family of microcontrollers using avr-gcc. In addition to configuring CMake for cross compiling with avr-gcc, the toolchain provides optional avrdude utilities.

Obtaining the Source Code

HTTPS:

git clone https://github.com/apcountryman/toolchain-avr-gcc.git

SSH:

git clone git@github.com:apcountryman/toolchain-avr-gcc.git

Usage (Dependency)

To use this toolchain, simply set CMAKE_TOOLCHAIN_FILE to the path to this repository's toolchain.cmake file when initializing CMake.

To use the avrdude utilities, add the path to this repository to the project's CMAKE_MODULE_PATH, and include avrdude-utilities.cmake. The avrdude utilities include the following functions:

• add_avrdude_target()
• add_avrdude_programming_target()
• add_avrdude_flash_programming_targets()
• add_avrdude_eeprom_programming_targets()

Documentation for the usage of the avrdude utilities can be found in the avrdude-utilities.cmake file in this repository.

Finding Tools

This toolchain expects to find avr-gcc, avr-g++, associated binary utilities, and avrdude in the path(s) searched by CMake's find_program() command. avrdude is only required if avrdude-utilities.cmake is included. If the toolchain fails to locate tools, consult the documentation for CMake's find_program() command.

Usage (Development)

This repository's Git pre-commit.sh hook script is the simplest way to configure, build, and test this project during development. See the pre-commit.sh script's help text for usage details.

./git/hooks/pre-commit.sh --help

Additional checks, such as static analysis, are performed by this project's GitHub Actions CI workflow.

Versioning

Post version 0.3.0, toolchain-avr-gcc will follow the Abseil Live at Head philosophy.

Workflow

toolchain-avr-gcc uses the GitHub flow workflow.

Git Hooks
