#1:[INDENT]

CAN_ReceiveMsg(LPC_CAN2,&RXMsg);

is used in

void CAN_IRQHandler()

of can_ledcontrol.c because this sample is using CAN interrupt to receive messages.
[/INDENT]#2:[INDENT] There's nothing wrong with MCP2551 (except it's using 5V supply voltage). Don't forget to pull RS low if you use higher baudrates :)[/INDENT]

Hello attori90,

I do not know how experienced you are in CAN, but it can be of use to look at the following link:

It is not an exact match on your question, but it may expand your knowledge.
