avr eeprom data change

[himanshu mittal]

sir/mam,

 

            i can’t understand the problem i am getting with eeprom. The eeprom data got changed when i try to on/off power supply many times simultaniouly..also my data got changed when i pressed the reset button many times..i can’t understand why my value at eeprom got changed.

It should not happen, please check if there is any errors in your code which will get affected due to this process. Imagine what will happen when the power goes off before a byte get completely written, research on that!
