For some reason i can’t get this example code to work as soon as I switch the codes around on each device it works.
Does anyone know what i’m doing wrong?
Xadow GSM
[code]#include <Wire.h>
void setup() {
Wire.begin(8); // join i2c bus with address #8
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©; // print the character
}
int x = Wire.read(); // receive byte as an integer
Serial.println(x); // print the integer
}[/code]
Arduino Mini
[code]#include <Wire.h>
void setup() {
Wire.begin(); // join i2c bus (address optional for master)
}
byte x = 0;
void loop() {
Wire.beginTransmission(8); // transmit to device #8
Wire.write("x is "); // sends five bytes
Wire.write(x); // sends one byte
Wire.endTransmission(); // stop transmitting
x++;
delay(500);
}[/code]
