Sign up using Email and Password. The EERandomRead function is defined similarly. Are you just writing to page zero? But i still can’t figure that out I have tried it but its not working. He’s trying to adapt, the question is reasonable and he needs encouraging.
He’s run into a problem at24c16s the library routines he is using rather than having a coding error per se.
AT24C16A, EEPROM, PDIP-8
To access more than addresses you will need to write your own routines that control the target chip appropriately.
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. AT24C16 has bytes per page. Roh 2, 5 27 Datzsheet problem here is actually with the I2C peripheral library, not your code.
The EEByteWrite function is defined as: If you are just writing a single byte at a time you don’t need to worry about pages. See my comment on his answer. The datasheet which I haven’t seen surely shows you the protocol used to address the memory?
As you can see the address parameter is an unsigned char which means it can only accept values up to Sign up using Facebook.

That’s only really for higher speed block transfers. This is a typical trap for the uninitiated and the question is a reasonable one.
