Post by thread:[PIC] 18F458 CAN dead in the water

Hello all, very occasional poster de-lurking now to ask a question. I searched the archives, there is clearly CAN knowlege on this list but nobody posted "the gotcha is...". I've been trying to get the CAN module going on an 18F458 for a week with no success. Have tried writing my own, and tried several of the code examples from Microchip ap notes with no luck. It must be something stupid, some register that's set wrong or summat. But I sure can't find it! Very frustrating because usually the Microchip peripherals are pretty straight forward. We do have a MCP2510 eval board and that's working fine with 16F876 that it came with, so we have a way to send things to the 18F and listen to it. But the 18F hears garbage at best and won't send at all. Even tried swapping out the 18F in desparation, of course that wasn't it. Any suggestions? Or if somebody has a simple piece of 18F CAN code that is tested and works, that I could use as an example, that would be super. It could do almost anything, short and simple is good. C or asm is fine. Once I have a working example I can run with it, but right now that first step is a big one! Thanks for your consideration. ---- Erik Kauppi spam_OUTekauppiTakeThisOuTcorsa-inst.com (734) 761-1545 --- ---- Corsa data acquisition: http://www.corsa-inst.com---- -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu>

Microchip has a new software tool, "Application Maestro" which will generate the basic CAN code for you.
