Arduino AVR CMake

Compile Arduino AVR programs using CMake.

Instructions

1. Clone this repository and open a terminal in the Arduino-AVR-CMake folder.
2. Ensure that the Arduino AVR core is installed correctly, this guide assumes that the core is in ~/.arduino15/packages/arduino/hardware/avr/1.8.6, that the toolchain is in ~/.arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7, and that avrdude is in ~/.arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17. If this is not the case, change it now in cmake/toolchain/avr.toolchain.cmake.
3. Configure the project using CMake by running the following command:

   cmake -S. -Bbuild \
       -D ARDUINO_PORT=/dev/ttyACM0 \
       -D CMAKE_TOOLCHAIN_FILE=cmake/toolchain/uno.toolchain.cmake \
       -D CMAKE_BUILD_TYPE=MinSizeRel
   

   Customize the port, toolchain file, and build type for your specific configuration.
4. Finally, build and upload the example “blink” program:

   cmake --build build -j -t upload-blink
   

   To compile the program without uploading, you can use

   cmake --build build -j -t blink
   

   If you're using an Arduino with a native USB interface (e.g. Leonardo), you'll have to press the reset button before uploading. You could automate this by opening its serial port at 1200 baud as part of the upload process.

VSCode

In VSCode, you can select the board you want to use using the CMake: Select a Kit command from the CMake Tools extension. Then select the right board as shown in the following image:

To build the sketch, you can either press F7 or click the Build button in the bottom ribbon or in the CMake side panel. To upload, you can use the upload-blink utility in the CMake side panel:
