According to the datasheet it must have addresses and I should be able to write unsigned int into it [ 1 unsigned int per 2 addresses] but I am only able to write unsigned ints onto addresses.

As you can see the address parameter is an unsigned char which means it can only accept values up to That’s the limit you are hitting. To access more than addresses you will need to write your own routines that control the target chip appropriately.

Are you just writing to page zero? The datasheet which I haven’t seen surely shows you the protocol used to address the memory? For example see this similar project datadheet describes the I2C protocol. It’s a shame to see this question not receiving a few upvotes.

He’s run into a problem in the library routines he is using rather than having a coding error per se. This is a typical trap for the uninitiated and the question is a reasonable one.

I checked the datasheet and found three pins as p0p1p2 meaning page control pins. The problem here is actually with the I2C peripheral library, not your code. The EEByteWrite function is defined as: The EERandomRead function is defined similarly.

See my comment on his answer. He’s trying to adapt, the question is reasonable and he needs encouraging.

I have tried it but its not working. But i still can’t figure that out If you are just writing a single byte at a time you don’t need to worry about pages. That’s only really for higher speed block transfers.
