It’s a shame to see this question not receiving a few upvotes. But i still can’t figure that out Roh 2, 5 27 Are you just writing at24c16s page zero?
AT24C16 has bytes per page.
Home Questions Tags Users Unanswered. This is a typical trap for the uninitiated and the question is a reasonable one.
The datasheet which I haven’t seen surely shows you the protocol used to address the memory? Sign up or log in Sign up using Google. The EERandomRead function is defined similarly.
See my comment on his answer. That’s the limit you are hitting.
AT24C16A, EEPROM, PDIP-8
c – Number of address in AT24C16 EEPROM or is it duplicate? – Electrical Engineering Stack Exchange
As you can see the address parameter is an unsigned char which means it can only accept values up to dattasheet To access more than addresses you will need to write your own routines that control the target chip appropriately.

It has 8 pages. I checked the datasheet and found three pins as p0p1p2 meaning page control pins.
If you are just writing a single byte at a time you don’t need to worry about pages. For example see this similar project which describes the I2C protocol. Sign up using Facebook. That’s only really at24cc16a higher speed block transfers. The EEByteWrite function is defined as: The problem here is actually with the I2C peripheral library, not your code.
