Hello, I would like to contribute the support for a board called Altair, I successfully got it working by making a custom board json file and putting it in ~/.platformio/boards and manually copying the custom pins_arduino.h to ~/.platformio/packages/framework-arduinoavr/variants/altair/.
Here are the files and instructions to manually install it: GitHub - Rodmg/altair-platformio: Altair Development Board support for PlatformIO
However this is not convenient as I have to copy the pins_arduino.h file again every time the framework is updated.
I’ve been looking at the platform-atmelavr github repository and I know that I could make a pull request for adding the board json definition, however I cannot find where to put the pins_arduino.h file.
Where are the board variant files located?
Thank you.
