Introduction

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

• Classic CAN Message Format.
• Message ID Type is Extended, Msg Id 0xD0, 0xD1, 0xD2, 0xD3, 0xD4.
• MCAN is configured in Polling Mode.
• Arbitration Bit Rate 1Mbps.
• Data Bit Rate 5Mbps.
• FIFO mode is used for Tx and RX to store message in message RAM.

5 Messages are transmitted and received back internally using internal loopback mode. When all the 5 messages received with the 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
