Are you just writing to page zero? I have tried it but its not working.
If you are just writing a single byte at a time you don’t need to worry about pages. The EEByteWrite function is defined as: The problem here is actually with the I2C peripheral library, not your code. I checked the datasheet and found three pins as p0datasheftp2 meaning page control pins.
Post as a guest Name. For example see this similar project which describes the I2C protocol. The EERandomRead function is defined similarly.
But i still can’t figure that out Sign up or log in Sign up using Google. It has 8 pages.

That’s the limit you are hitting.
See my comment on his answer. To access more than addresses you will need to write your own routines that control the target chip appropriately.
As you can see the address parameter is an unsigned char which means it can only accept values up to That’s only really for higher speed block transfers. Roh 2, 5 27 It’s a shame to see this question not receiving a few upvotes.
