Description

AVR development using conan>=2.0.7.

Provide the toolchain

Microchip

> cd toolchain/microchip
> conan create .
...
> cd ../..

Zak Kemble

Alternative toolchain using Zak Kemble:

> cd toolchain/zakkemble
> conan create . --version 14.1.0
...
> cd ../..

Provide the conan AVR settings

Install conan/settings_user.yml into ~/.conan2/.

Compile the example project

> cd blink
> conan build . -pr:h ../conan/profiles/arduino_uno
...
> conan build . -pr:h ../conan/profiles/arduino_uno -s build_type=Debug
...

Advanced editors, like Clion, can use cmake presets, now we have:

> cmake --list-presets
Available configure presets:

  "conan-atmega328p-minsizerel" - 'conan-atmega328p-minsizerel' config
  "conan-atmega328p-debug"      - 'conan-atmega328p-debug' config

> conan install . -pr:h ../conan/profiles/arduino_uno
...
> source build/Debug/generators/conanbuildenv-debug-avr.sh
...
> cmake --preset conan-debug
...
> cmake --build --preset conan-debug --verbose
...
> source build/Debug/generators/deactivate_conanbuildenv-debug-avr.sh
Restoring environment

> file build/Debug/blink.elf
build/Debug/blink.elf: ELF 32-bit LSB executable, Atmel AVR 8-bit, version 1 (SYSV), statically linked, with debug_info, not stripped

Potential

Other compiler

• Arduino AVR toolchain
• PlatformIO AVR toolchain
• https://github.com/modm-io/avr-gcc
• https://blog.zakkemble.net/avr-gcc-builds/
• Build AVR toolchain from source

Offer HALs

• TODO

AVR friendly libraries

• ETL
• ArduinoJson

AVR architecture

Conan settings have the MCU specified as arch, this means no reuse between other atmegas. Perhaps we can use the arch there.
