Communication in MATLAB
Configure CAN hardware; send and receive messages on a
network
Hardware connection functions define a connection to a CAN interface hardware that establishes a physical connection to a CAN bus. The CAN Transmit Workflow shows how to pack and transmit CAN messages with MATLAB®. You can also employ event-based message transmission; load and replay messages. The CAN Receive Workflow shows how to receive and unpack CAN messages.
For building Simulink® models that use CAN blocks to transmit and receive messages on the network, see Communication in Simulink.
