This example shows how to use Simulink® Support Package for Arduino® Hardware to transmit and receive data from the CAN network using the specified CAN device.
Arduino Mega 2560
Arduino Mega ADK
Arduino MKR WIFI 1010
Arduino Nano 33 IoT
Before you start this example, you must:
To run this example, you must have the following hardware:
Supported Arduino board
OBD(On-board diagnostics) Connector
MCP2515 based CAN shield
1. Connect the CAN Shield on the Arduino board.
2. Connect the OBD Connector from the vehicle to the MCP2515 based CAN shield. For more information on MCP2515, see MCP2515.
1. In your Simulink model, click Modeling tab and then select Model Settings to open Configuration Parameters dialog.
2. Select the Hardware Implementation pane and select your required Arduino hardware from the Hardware board parameter list. Do not change any other settings. For information on setting or modifying the CAN properties, see Model Configuration Parameters for Simulink Support Package for Arduino Hardware
3. Click OK.
This example uses the Arduino CAN Transmit model, with a CAN Transmit block, to transmit 1 byte of data from the Arduino hardware. To open the model, enter the following command at the MATLAB command prompt.
1. Set the CAN Transmit block parameters as shown in this image.
2. In your Simulink model, click the Hardware tab and then click Monitor & Tune to transmit the data.
This example uses the Arduino CAN Receive model, with a CAN Receive block, to receive 1 byte of data by the Arduino hardware. To open the model, enter the following command at the MATLAB command prompt.
1. Set the CAN Receive block parameters as shown.
2. In your Simulink model, click the Hardware tab and then click Monitor & Tune to receive the data. The Scope block displays the received data in the target hardware.
