OK - I have the EEPROMS setup per what has been described, and we can compile and it LOOKS like it sends data to the chips, but I cant' see anything coming back.. I read in 1000 values from 0 to 999 in an 'x' loop, then read them back, and all I see are '0's... Help! I think my naming of the chips is wrong..

Chip is an 16F876A.

I have two chips 24LC515 512k .. I have given them names:

DPIN var PortA.2 ' I2C data
CPIN var PortA.1 ' I2C clock
address var byte
value var byte

Chip1 con %10100000 ' address of chip1
Chip2 con %10100100 ' address of chip2

Init:
PORTA = %00000 'Initialize PortA to all zeros - all output
TRISA = %00000 'All port A output
PORTB = %00000101 'Initialize PortB - port 2 for data, port 0 for button interrupt
TRISB = %00000101 'Port 2 inputs are 0 and 2
T1CON = %01000000 'Timer1 1:1 prescale(?). Timer1 off
----------------------------------------------------------------------

I read and write to them like this: For this demo I only will write 1000 records in each chip.
