beginner for Can bus using MCP2551
PostPosted: Fri Apr 12, 2013 12:34 pm     Reply with quote
I have school project that I must connect PICs by CAN bus. I have not so much source about can bus. Please help me.
As I search I must use MCP2551 to connect to CAN L&H line. So I have PIC16F877A, PIC18F452 & PIC18F458. For example in PIC18F452 I must use can-18xxx8.c.
So I don't know how I must use it to communication and if I use it is it need to connect with MCP2515 to MCP2551. What about other PICs ?
Is it a training about it?

Question Exclamation Sad Confused Crying or Very sad

That is not correct. 18F452 does not have a built-in CAN bus module.
The can-18xxx8.c file will not work with 18F452.

For PICs that do not have a built-in CAN bus module, you must use
an external CAN bus chip, such as MCP2515.

It's easier if you use PICs with a built-in CAN bus module, such as
18F458, or 18F4580, etc. Then you only need to add the MCP2551
transceiver chip.
