Add RS485 transciever(s) #6

Open Atmelfan opened 4 years ago

New servos uses RS485 for communication and will thus require a transciever on the carrier. Prefably both the jetson TX2 and the onboard MCU will be able to commicate with the servos (or eachother).

Possible solutions:

  1. TX2 and the MCU get their own transciever connected to a shared bus.
  2. A single transciever shared/multiplexed by both the TX2 and the MCU.
  3. Single transciever controlled by MCU which forwards commication from TX2 serial interface (will require a custom driver in TX2 firmware)

ATM option 1 looks like the best solution.
