CAN

R2026b

Communication using CAN protocol

Controller Area Network (CAN) is a robust communication protocol that enables communication between multiple devices. Use CAN to efficiently design and implement reliable CAN-based communication systems.

Blocks

	CAN Transmit	Transmit message to CAN network
	CAN Receive	Receive message from CAN network
	On-board CAN Receive	Receive messages using on-board Arduino CAN controller (Since R2024b)
	On-board CAN Transmit	Transmit messages to CAN network using on-board Arduino CAN controller (Since R2024b)

XCP on CAN with Arduino

Set Up, Deploy, and Calibrate Arduino Application Using XCP on CAN

Set up XCP on CAN communication, deploy a Simulink^® application to Arduino^®, and perform real-time monitoring and calibration using Simulink or third-party calibration tools.

STEP 1: Set Up CAN Hardware on Host Computer for XCP on CAN Communication
STEP 2: Configure Model for XCP on CAN External Mode
STEP 3: Generate A2L File for Third-Party Calibration Tools Using XCP on CAN Host Communication
