Description

The official code example from Infineon (MULTICAN_1_KIT_TC275_LK) demonstrates the use of the MultiCAN module for internal CAN data transmission. It establishes communication between CAN Node 0 and CAN Node 1 within the same board by using Loop-Back mode.

While this setup is useful for verifying internal functionality, Loop-Back mode shall be disabled to allow actual CAN communication with external devices.

The steps for a successful CAN transmission with Loop-Back OFF are:

 • CAN Initialization – Provided in initMultican()
    -> CAN module configuration and initialization
    -> Source CAN node configuration and initialization
    -> Source message object configuration and initialization
 • CAN Pins configuration
 • Enable CAN transceiver
 • CAN message transmission – Provided in transmitCanMessage()
 • Interrupt Service Routine – Provided in canIsrTxHandler()
