How can a host PC know if the RMP motors are not powered?

When the CUs shutdown as a result of a fault and/or estop request, there should be no traffic on the CAN bus with the exception of the ESTOP message from the deuce to the CUs (message id 0x412). Over USB, a heartbeat message will continue from the deuce board which will indicate that no data has bee...

How to differentiate between CU_A vs CU_B?

Q: I am having trouble figuring out which CAN bus I am communicating with (A or B). What happens if I send command to CU_B? Is there a way to tell which is which?

CAN message monitor data - high & low?

Q: On monitor data message 4 and 5, what does "high" and "low" mean. Does that mean it is a 32 bit number?
A: The "high" and "low" refer to the byte order. Each number is a 16 bit (2 byte) value. To compute the actual value, you would use x = (high_byte << 8) | low_byte
