yes, it should say
x is 0x00
x is 0x01
x is 0x02
…
so perhaps something in the wiring is wrong?
I don’t have the hardware you do but I have 2 UNO’s.
The other day I watched a video where I2C was explained by pushing buttons for clock and data on a breadboard to write and read data to an EEPROM. By the time is was done I understood more about I2C than ever yet still I don’t know that library!
Here is the example program in my 1.03 IDE:
// 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
Wire.endTransmission(); // stop transmitting
x++;
delay(500);
}
