Hi I want to bypass the CAN transceiver TJA 1040 and connect the Tx of one CAN controller to Rx of another and vice versa. The CAN does not seem to work. Can anyone suggest why this is so? Many thanks
Hello, the CAN protocol needs to be connected to the CAN line even to receive what it is transmitting, so just connecting Tx to Rx will not work. This Application Note will show you how to do it.
