I'm not really an expert in CAN protocol communication but I know minimum about it. I read some forums which talk about transceiver and controller, which are necessary to communicate into CAN protocol.
So I take a MCP 2551 transceiver made by Microchip; but for the controller part, I don't even know if the microcontroller STM32 has an internal controller or not.
My question is the following one:
If the microcontroller STM32 has an internal controller how does it work.
And if it's not, what can I buy for it?
Thanks answer to my questions.
