I've searched the forum for SPI but nothing useful comes up that I can use. Right now I'm taking it slow and I'm not worrying about the CAN portion yet. I only want to understand SPI right now and get the 18F4550 and MCP2515 to talk to each other. Can someone help me get the ball rolling and point me in the right direction. If there are some sample codes that would be great!
