I am trying to get a CAN_LDD interface working on a MK60FX512 and I am noticing that the SYNCH bit in ESR1 of the Flexcan module is set, meaning that the "FlexCAN is not synchronized to the CAN bus."
I can only assume that this is why when I send data from the micro to another device, that the data doesn't come across.
I am using the "Sending data frame with interrupt service" example provided in the documentation and the CAN1_OnFreeTxBuffer is never hit on a break point.
Also, is it correct that I would be seeing pulses on the CAN bus if I am not actively sending data? I don't recall from the standard if there is continual packets for timing being transmitted.
