# MCAN

## Overview

The mcan_demo provides the following features:
- loopback test for all SoC supported CAN controllers, focusing on the CAN and CAN-FD test
- loopback test for the board supported CAN controllers using interrupt mode
- Dual-board Echo test
- Send out multiple messages for the CAN bus connection check
- CAN filter test
- CAN RXBUF test
- CAN Timestamp test

## Board Setting

No special settings are required

## Running the example

When the example runs successfully, the board shows the following menu:

```console

*                                                                             *
*                         CAN Example Menu                                    *

* 0 - Run loopback test for all supported CAN controllers (CAN and CANFD)     *
* 1 - Run loopback test for board supported CAN controller (interrupt mode)   *
* 2 - Echo test between two board:initiator                                   *
* 3 - Echo test between two board:responder                                   *
* 4 - Send multiple classic CAN messages for transmission check               *
* 5 - Send multiple CANFD messages for transmission check                     *
* 6 - CAN error test (Need to remove current node from CAN BUS for this test) *
* 7 - CAN filter test                                                         *
* 8 - CAN RXBUF test                                                          *
* 9 - CAN TX EVENT FIFO test                                                  *
* a - CAN Timestamp Test                                                      *
* b - CAN timeout counter Test                                                *
*                                                                             *

### Note:

- For option 0 and option 1, users can start the test by typing the option directly
- For option 2 and 3, users must connect two boards and run this demo, start the responder first, then start the initiator.
- For option 4, users must ensure that the board is attached to a valid CAN bus. If the board is connected to a CAN monitor, and users can see multiple messages will be sent out after this option is chosen.
