Many of the system power distribution boards require CAN communication to turn off individual relays on the board, and read information such as that of current, voltage, etc.
We are planning to use CAN Open as it is widely supported.
There should be a library you can use for CAN Open on the STM32.
Research is needed on how to create a dictionary file for the CAN node, and how to communicate with the STM32.
A simple implementation of CAN communcation on one of the STMs for a demo would be nice.
