It covers steps like socket creation, binding to the CAN interface, sending, and receiving CAN frames. Feel free to modify the frame ID, data, and other parameters according to your specific needs.//n//nIf you are using Windows, you would need to use a different CAN communication library and modify the code accordingly.///
