I need to use a piece of flash memory to store variables that will be provided and modified by the User, in this case, I need to use an external flash memory, or can I reserve a piece of memory of the ATMEGA? These variables can be changed at any time, but must remain in memory when shut down the Arduino.
I shall be grateful if someone can help me
There is eeprom memory built into the arduino for this purpose.
512 bytes on the 168, 1K on the 328.
Thanks! That's exactly what I needed!
I thought that it was more difficult to handle
