EEPROM.put(i,password3);
}

Try to add EEPROM.commit(); just after the put

- Fri Jan 29, 2016 5:40 am #39929 Maybe it is just that the int type is 2 bytes, so you should count up to 255.

- Sun Jan 31, 2016 10:34 am #40073 Does this put work as the standard put from the arduino EEPROM.h librarie in the way that it only writes if the data changes?

- Mon May 30, 2016 11:09 am #48265 Try this:

Code: Select all#include <EEPROM.h>

void setup()
{
  EEPROM.begin(512);
  Serial.begin(115200);
  pinMode(BUILTIN_LED, OUTPUT);
  // write a 0 to all 512 bytes of the EEPROM
  int i=0;
  int data=0;
  while(i<512){
   EEPROM.put(i, data);
   Serial.println(i);
   delay(50);
   ++i;
  }
  // turn the LED on when we're done
  Serial.println("Done!");
  digitalWrite(BUILTIN_LED, LOW);
  EEPROM.end();
}

void loop()
{
}
