I made my address a WORD because the 24AA1025 (1024K I2C™ CMOS Serial EEPROM) has a 2 byte address. So in theory this should work but as you can see the output is reading "0" in every address when it should be reading "5"
Does my code look right?
I am unsure of the PAUSE 10ms as I can't find any specs in the data sheet for the amount of time needed after each WRITE cycle. I tried commenting out the delay but still the same results. One would think if the delay was wrong I would still get a "5" in Addr0 at the very least.
Here is the schematic I used to wire up the 24AA1025 to my 16F88:

Here is the code:
And here is what I get on Hyperterm:Code:SO con 0 ' Define serial output pin T2400 con 0 ' Set serial mode DPIN var PORTA.0 ' I2C data pin CPIN var PORTA.1 ' I2C clock pin B0 var WORD ' Address B1 var byte ' Data from first address read B2 var byte ' Data from second address read B3 var byte ' Second Address For B0 = 0 To 15 ' Loop 16 times I2CWRITE DPIN,CPIN,$A0,B0,[5] ' Write a "5" to each location Pause 10 ' Delay 10ms after each write Next B0 loop: For B0 = 0 To 15 step 2 ' Loop 8 times high 3 ' LED on to signify a Read in progress I2CREAD DPIN,CPIN,$A0,B0,[B1,B2] ' Read 2 locations in a row B3 = B0 + 1 ' Create second address for print Serout SO,T2400,["Addr",#B0,":",#B1,13,10,"Addr",#B3,":",#B2,13,10] ' Print 2 locations B3 = 0 ' Zero out B3 Variable low 3 ' LED off to signify no read in progress Next B0 Serout SO,T2400,[13,10] ' Print linefeed Goto loop
