Control Area Network (CAN)

CAN is a multi-cast network system that connects multiple microcontrollers. It allows micro controller to share information.

Each microcontroller exchanges information using an identification number and a semaphore.

When an microcontorller is ready to send or receive information, it set a semaphore flag and the CAN controller enables transmission based on the priority of the semaphores.

CAN is used to monitor and control multiple operations. Examples: automotive systems, navigation systems, oil drilling, flight simulators.
