Hello All,

I have a problem testing the loop back mode for CAN controller on LPC1857. I am using the can example of LPCopen. I am able to successfully transmit the message. The status register value after the transmission is "1000" which indicates that the transmission is successful. I am having problems knowing whether the transmitted message has come back again. The status register also does not indicate whether a new message has been received.

Can anyone please tell me how to check whether the transmitted message has been received back.
