Does not work.
Used copy/paste to create the sketches. The sketches are pasted below.
See: "--- THE SKETCH HANGS HERE ---" Below in the Master Writer Code.
Very new to Arduino; What am I missing?
Master Writer Code - Program for Arduino 1
// 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.
#include <Wire.h>
void setup()
{
Wire.begin(); // join i2c bus (address optional for master)
}
byte x = 0;
void loop()
{
Wire.beginTransmission(4); // transmit to device #4
Wire.write("x is "); // sends five bytes
Wire.write(x); // sends one byte
--- THE SKETCH HANGS HERE ---
Wire.endTransmission(); // stop transmitting
x++;
delay(500);
}
Slave Receiver Code - Program for Arduino 2
// Wire Slave Receiver
// by Nicholas Zambetti http://www.zambetti.com
// Demonstrates use of the Wire library
// Receives data as an I2C/TWI slave device
// Refer to the "Wire Master Writer" example for use with this
// Created 29 March 2006
// This example code is in the public domain.
#include <Wire.h>
void setup()
{
Wire.begin(4); // join i2c bus with address #4
Wire.onReceive(receiveEvent); // register event
Serial.begin(9600); // start serial for output
}
void loop()
{
delay(100);
}
// function that executes whenever data is received from master
// this function is registered as an event, see setup()
void receiveEvent(int howMany)
{
while(1 < Wire.available()) // loop through all but the last
{
char c = Wire.read(); // receive byte as a character
Serial.print(c); // print the character
}
int x = Wire.read(); // receive byte as an integer
Serial.println(x); // print the integer
}
