Small driver to add the RAK1903 ambient light sensor to MeshCore. It has been running for a few months without issue.

Uses CayenneLPP Luminosity reporting. Modeled off TI's datasheet.

Tested on:

  • RAK19001 sensor firmware

Omitted from lilygo_tdeck firmware as that build disables sensors by default, mirrored existing behavior.

Data screenshots:
