AT24CM02 EEPROM, data that is read is different from data that is written

[VYoun]

Hello guys,

I am trying to integrate and EEPROM into my system (based on STM32H7).

I managed to write a struct into the EEPROM. However, the data that I read is different from the data that I have written.

Is this a known problem with EEPROMs?

Any help is greatly appreciated.

Thank you and best regards,

Reading and writing to EEPROMs should work correctly. You don't give many details, so it's hard to guess at what may be wrong.

Hello,

I was writing two functions to read and write to EEPROM. I was giving a wrong address in the functions.

You are right the EEPROM works fine, thank you for your help.
