Posted on December 13, 2013 at 17:20CAN requires at least two nodes in order to work. I'm trying to determine what the error signature is for a node that is not connected to the network so that the node can go into a timed sleep/retry mode rather than constantly report errors in the CAN SCE interrupt. For example, in a multiple node network one node starts before all others, but since no other nodes are present it looks like the node is not connected. But I haven't been able to identify the sequence of errors (TEC, REC, EPV, EWG, BOf flags) that are unique to a disconnected node.
Has anyone worked out how to discriminate between normal CAN bus errors and a physical disconnection?
