CRC generation with PIC C Compiler

[Bil]

Hi Guys, I'm working with iButtons at the moment and have written a CRC
generation routine that is HUGE, I know that there is a simple crc
generation routine out there but I dont know it. Any help will be great.
I'm using the CCS C compiler

Google for "A painless guide to CRC error detection algorithms" by Ross
Williams. After reading it, you should find it fairly straightforward to
put together a table-driven implementation.
