清除EEPROM

#include <EEPROM.h>

void setup(){

EEPROM.begin(512);

for (int i = 0; i < 512; ++i) {

EEPROM.write(i, 0);

}

EEPROM.commit();

}

void loop(){}

寫入EEPROM

#include <EEPROM.h>

String sssid = "yourssid";

String spass = "yourpass";

void setup(){

EEPROM.begin(64);//使用64bytes EEPROM 最多512

for (int i = 0; i < sssid.length(); ++i)

{EEPROM.write(i, sssid[i]);}

for (int i = 0; i < spass.length(); ++i)

{EEPROM.write(32+i, spass[i]);}

EEPROM.commit();

}

void loop(){}

讀取EEPROM

#include <EEPROM.h>

String Essid = "";

String Epass = "";

void setup(){

EEPROM.begin(64);

for (int i = 0; i < 32; ++i) {

Essid += char(EEPROM.read(i));

}

for (int i = 32; i < 64; ++i)

{ Epass += char(EEPROM.read(i)); }

}

void loop(){}
