Master CAN Protocol for embedded system in (Arabic) بالعربي

 CAN Protocol for Embedded Systems in Arabic

This course will teach you everything you need to know about the CAN protocol for embedded systems. You will learn about the CAN protocol, CAN frames, CAN bus characteristics, and how to read a CAN controller from a TRM. You will also learn how to use Linux CAN sockets to communicate with CAN devices.
