I have a trouble in using NI CAN in LabVIEW.
I use channel API to read messages. I found that ,running the same program, sometimes I can receive the messages successfully, sometimes can't receive the messages all the time when these messages were being transfered on CAN bus, but the read.vi didn't return error code but warning of no messages. I think there must be something wrong happened in CAN hardware, but why the read.vi didn't return error code to inform me?
