CAN Network Communication

Send and receive messages over CAN bus

Controller Area Network (CAN network) is a vehicle bus standard that allows microcontrollers and devices to communicate with each other within a vehicle. CAN is a message-based protocol originally designed for automotive applications, but it is also used in other areas such as industrial automation.

MATLAB and Simulink together with Vehicle Network Toolbox let you:

• Connect your PC to your CAN network using a variety of supported CAN interface hardware.
• Send and receive CAN messages over your CAN network
• Send and receive messages using XCP protocol
• Filter CAN messages
• Use CAN database files to encode and decode messages
• Generate code from CAN Simulink blocks
