CAN_LDD

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.

Hello Mark,

- "the SYNCH bit in ESR1 of the Flexcan module is set", this meaning FlexCAN is synchronized to the CAN bus.

- And , could you please tell me which DOC ?

And also do you meaning when you test the example you mentioned , it can not work well ? If yes,

please tell me which , i can check on my side .

You can also describe your problem in detail .
