WIP
What
This PR adds a new feature. You can now have two LilyGo's talk to each other via serial! (Modbus pins)
Why
Some inverters cannot be on same CAN bus as automotive CAN frames (Solax / Foxess). Having a separate CAN channel for the inverter becomes mandatory. Other HW solutions exist like adding more CAN channels, but this PR adds another alternative to that; Two LilyGos working in tandem:
How
The USER_SETTINGS.h file now has two new defines, that when enabled turns on this functionality:
#define SERIAL_LINK_RECEIVER //Enable this line to receive battery data over RS485 pins from another Lilygo (This LilyGo interfaces with inverter)#define SERIAL_LINK_TRANSMITTER //Enable this line to send battery data over RS485 pins to another Lilygo (This LilyGo interfaces with battery)A new library has been added to the lib folder for this serial communication protocol. Massive thanks to @mackelec 🙌
