Introduction

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

• CAN FD Message Format.
• Message ID Type is Standard, Msg Id 0xC0.
• MCAN is configured in Interrupt Mode.
• MCAN Interrupt Line Number 0.
• 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.

Using SDK with SysConfig

A GUI tool SysConfig is used to configure different modules and peripherals of the example. Using this tool, users can select and customize different modules and peripherals. The SysConfig tool will generate the code for initializing and configuring these modules. This configuration is saved to a file called example.syscfg for every example.

Using SDK with SysConfig

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
