Minor Project - external EEPROM management: software from Nicholas Zambetti; his WIRE library

This is the wire library!


Some very nice & simple stuff from Nicholas Zambetti.
Just needs adapting for what i want - which isn't complicated..

/*
Wire Master Writer by Nicholas Zambetti

Demonstrates use of the Wire library
Writes data to an I2C/TWI slave device

#include Wire.h

void setup()
{
Wire.begin(); // join i2c bus (address optional for master)
}//setup()

byte x = 0;

void loop()
{
Wire.beginTransmission(4); // transmit to device #4
Wire.send("x is "); // sends five bytes
Wire.send(x); // sends one byte
Wire.endTransmission(); // stop transmitting

x++;
delay(500);
}//loop()

void setup()
{
Wire.begin(4); // join i2c bus with address #4
Wire.onReceive(receiveEvent); // register event
Serial.begin(9600); // start serial for output
}//setup()

}//loop()

// function that executes whenever data is received from master

void receiveEvent(int howMany)
{
while(1 < c =" Wire.receive();" x =" Wire.receive();">
