MCAN blocking

This example application shows how to use the MCAN module to transmit and receive CAN messages in polling mode.

Description

This application transmits and receives CAN messages on the CAN bus. To run this application, an evaluation board and Microchip CAN Bus Analyzer is required . They act as different nodes on the CAN bus. While running the application, user can send and receive CAN messages between the board and the analyzer.

Downloading and building the application

To clone or download this application from Github, go to the main page of this repository and then click Clone button to clone this repository or download as zip file. This content can also be downloaded using content manager by following these instructions.

Path of the application within the repository is apps/mcan/mcan_normal_operation_blocking/firmware .

Setting up SAMA5D2 Xplained Ultra Evaluation Kit

Addtional hardware required

To run the demo, the following additional hardware are required:
- Microchip CAN Bus Analyzer
- ATA6563 click board

Setting up the board

Install Microchip CAN Bus Analyzer software on PC
Connect Microchip CAN Bus Analyzer to ATA6563 click board using female to female DB9 serial cable

Connect ATA6563 click board to the SAM A5D2 XULT as per the Pin connections shown below

SAMA5D2 XULT	ATA6563 click board
CANTX0 (PIN8), J9 Connector	RX (PIN 14)
CANRX0 (PIN7), J9 Connector	TX (PIN 13)
3V3 (PIN20), EXT1 Connector	3V3 (PIN 7)
VDD_5V (PIN3), J24 Connector	5V (PIN 10)
GND (PIN19), EXT1 Connector	GND (PIN 9)

Connect Microchip CAN Bus Analyzer to PC using USB Male-A to Male Mini-B cable
Short jumper JP2 (DEBUG_DIS)
Connect the Debug USB port on the board to the computer using a micro USB cable

Running the Application

Build the application using its IDE
Open the Terminal application (Ex.:Tera term) on the computer.
Connect to the EDBG/Jlink Virtual COM port and configure the serial settings as follows:
- Baud : 115200
- Data : 8 Bits
- Parity : None
- Stop : 1 Bit
- Flow Control : None
Open the CAN Analyzer Software and perform following steps
- Configure CAN Analyzer Software as per Hardware Setup mention in below screenshot
- Send CAN message from CAN Analyzer Software
Received message will be echoed back to the CAN analyzer software and terminal window
Following will be terminal session’s output
LED toggles for every message received

Following table provides LED name:
