Добрый день. Не могу обуздать i2c протокол с микросхемой 24с01. Ниже скетч. Что не так? Сериал молчит

Адрес выставил А0. Все А1, А2, А0 - на минусе.

// Wire Master Writer
// by Nicholas Zambetti <http://www.zambetti.com>

// Demonstrates use of the Wire library
// Writes data to an I2C/TWI slave device
// Refer to the "Wire Slave Receiver" example for use with this

// Created 29 March 2006

// This example code is in the public domain.

#define aD  0xA0
#include <Wire.h>

void WRITE(byte adress, byte date)
{
  Wire.beginTransmission(aD); // transmit to device #4
  Wire.send(adress);        // sends five bytes
  Wire.send(date);              // sends one byte  
  Wire.endTransmission();  
}

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