寫入方法：

void??writeway(int address , int val)
{
? Wire.beginTransmission(0x50); // transmit to device #44 (0x2c)??? // eeprom device address 0x50
?????????????????????????????? // device address is specified in datasheet

?Wire.write(address);
? Wire.write(val); ? ? ? ? ? ? // sends value byte ?
? Wire.endTransmission(); ? ? // stop transmitting

? val++; ? ? ? ?// increment value
? if(val == 64) // if reached 64th position (max)
? {
? ? val = 0; ? ?// start over from lowest value
? }
? delay(5);
}

讀取方法：

?

int readway (int address)
{

?Wire.beginTransmission(0x50); // transmit to device #44 (0x2c)??? // eeprom device address 0x50 ?????????????????????????????? // device address is specified in datasheet

?Wire.write(address);???????? // sends value byte ?

?Wire.endTransmission(); ? ? // stop transmitting

? Wire.requestFrom(2, 6); ? ?// request 6 bytes from slave device #2

? while(Wire.available()) ? ?// slave may send less than requested
? {
? //? char c = Wire.read(); ? ?// receive a byte as character
?// ? Serial.print(c); ? ? ? ? // print the character
? }

return Wire.read();
}
