I couldn't find this when I went looking for it. So I modified the example in the crc_xmodem_update function, to come up with the following code. This saved me 252 bytes vs. a lookup table. I don't know if this CRC is too specific to this application to be included in this project or not, but here it is anyways. Maybe it will help someone.
