-Added RAK_4631 define back
-Added includes for common RAK sensors that are currently supported in ESM
-Set global variables to static
-Reduced delay time within the RAK gps init sequence
Changes to migrate sensor code to the ESM.
Added a separate GPS init sequence for the RAK that scans I2C and Serial1 on the various sockets of the various base boards to find the RAK12500. (and soon the RAK12501)
Removed the GPS specific envs from platformio.ini and enabled GPS for all envs.
Verified working with RAK12500 on RAK19007 sockets A and D, as well as RAK19003.
There is a lot to this PR, so if there are any questions let me know.
The idea here is to merge T-Beam fw so that there is less redundant code. Most versions (except the 0.7) share PMU code, init sequence, and most IO pin definitions.
- Merged all T-Beam board.h files into one TBeamBoard.
- Added PMU code to identify different AXP chips.
- Modified "lilygo tbeam SX1276" variant to cover all T-Beam SX1276 versions
- Modified "lilygo tbeam SX1262" variant to cover all T-Beam SX1262 versions
- Enabled GPS on all T-Beam versions/models
- Enabled BME280 on the Supreme
I am also updating EnvironmentSensorManager to allow for boards that do or don't have GPS enable pins, as well as a PERSISTANT_GPS define check for boards that want GPS to stay active after boot.
