It's possible read or write an 24cxx in a circuit whit address pin 1,2,3 are fixed a vcc, as an in-circuit programming, then with a starting address different from 00
Thanks

The algorithm implemented communicates with the device at address 0; it's fairly easy to change the address in the source code.
I'm not sure why you want to start from locations other than 0; if the need is to retain part of the memory it would be better to first read, then modify only the area you need to change, then write everything.

I would like to know the same thing...? I dont think he was referring to the address at which to write the data but rather the physical address of the eeprom on the I2C bus. i.e. A0 A1 and A2. I have the same problem when trying to write to an eeprom in circuit with the address pins tied to ground i get communication timed out. Any advice? Thanks in advance!

Same answer: you should change the source code to address a different device.
