Introduction

This example demonstrates the CAN message transmission and reception in digital loop back mode for standard and extended CAN with the following configuration.

• Message ID for standard and extended CAN is 0x1C and 0x29E respectively.
• MCAN is configured in Interrupt Mode.
• Arbitration Bit Rate 1Mbps.
• Data Bit Rate 5Mbps.
• Buffer mode is used for Tx and RX to store message in message RAM.

Message is transmitted and received back internally using internal loopback mode. When the received message id and the data matches with the transmitted one, then the example is completed.
