The MattairTech Xeno Mini with D51 chip has not been added to the supported boards. It’s on Mattair’s roadmap and there’s a PlatformIO feature request for it too. In the meantime, how can I leverage the Arduino IDE core packages for this board with PlatformIO? I really want to be able to edit using PlatformIO (and vis-a-vis VS Code) and then use Arduino to build. This would be fine if it weren’t for the fact that the sketch no longer has a .ino file. What shall I do in the meantime? Thanks!
