写入方法：
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);
}
读取方法：
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();
