The compiler used in those examples is Hi-tech lite v9.6.

Ah... But they compile as is with XC8.... The above error is because I didn't copy the hex table over after writing it....

Thanks for finding that bug... Here is the hex table..

C:

unsigned char HEX_Table[] = {0x30, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36,
               0x37, 0x38, 0x39, 0x41, 0x42, 0x43,
               0x44, 0x45, 0x46};

Ian,

Out of curiosity, how long has that bug been in there?

Ooooh! since forever!!

The trouble is... The hex function isn't used in tutorial 7... So the HiTech compiler gave a warning!! But XC8 complains, even though it isn't compiled????

All he needed to do was delete the function...
