hello everybody,
I have never used or came across CAN (Controller Area Network) I tried to collect some information about it. I found it to be more commonly used in the industry, automotive domain. I saw an example that show its use in cars to exchange information between different electronic components I want to know how it does communicate.
I found CAN specification http://esd.cs.ucr.edu/webres/can20.pdf I am reading this but I do not understand what is happening. I understand that there is a master and slaves in the communication process Master can send data to slave, or it can receive data from slave via CAN bus.
What we need to know to do firmware development ? Does CAN also have fixed signals ? Like there is one in uart, there are two in I2C and four for SPI
