I want to experiment with a beta version of the Arduino mbed core for nano33ble.
I’ve hacked it by replacing .platformio/packages/framework-arduino-nrf52-mbedos with the beta version and copying the package.json from the original.
Now I’d like to do something that is more maintainable: I’d like to be able to choose on a per-project basis whether to use the release framework or the beta framework.
I’d appreciate some guidance on how to set that up. I’ve been trying to grok how platforms, packages, etc all fit together but I haven’t quite gotten it yet.
