I am using an Arduino Uno, and I use the EEPROM to store some presets. It works fine. But, when I reprogram the Arduino, the EEPROM gets wiped out. Is there a way to prevent this, and have the EEPROM not change after the Arduino is programmed?
I am using a USBtinyISP programmer.
Thank you very much for your help, and advance.
Here is the verbose result of my programming:
Sketch uses 5,298 bytes (16%) of program storage space. Maximum is 32,256 bytes.
Global variables use 286 bytes (13%) of dynamic memory, leaving 1,762 bytes for local variables. Maximum is 2,048 bytes.
