Has anyone implemented serial EEPROM reading and or writing with High Tech's
PIC C compiler?  I'm using a PICDEM-2 with a PIC16C74.  I have attempted to
write some code using the included i2c subroutines with no luck.  If anyone
has done this, could you please post the way to do it?  Here is what I have
so far:

When this code runs, I get both errors and the code erroneously reports -1
as the value of all 128 EEPROM locations.

Thanks!
