CAN (controller Area Network) is a serial bus system used to communicate between several embedded 8-bit and 16-bit microcontrollers.
It was originally designed for use in the automotive industry but is used today in many other systems(e.g. home appliances and industrial machines).
Highest Baud Rate is 1Mbit
CAN uses a message oriented transmission protocol.
There are no defined addresses, just defined messages.
SOF - Start of Time
Identifier - Tells the content of message and priority
RTR - Remote Transmission Request
