-// ---------------------------------
-// Stress test program/example for TinyWireS I2C library.
-// Run this master program on the Arduino Uno R3.
-// Run the other slave program on the Attiny.
-// ---------------------------------
-// Written by Scott Hartog, 2/6/2016
-// This is the I2C master program which runs on on a regular Arduino
-// (not a AtTiny). This program uses the regular Wire library from the Arduino IDE.
-//
-// It performs these steps in a loop:
-//    1. picks a random number of bytes between 1 and 12
-//    2. sends that many bytes of random data to the AtTiny slave within
-//       a single Wire.beginTransmission() / Wire.write() / Wire.endTransmission() set
-//    3. reads that same number of bytes back with a single Wire.requestFrom() call
-//    4. compares the received data to the originally transmitted data
-//    5. displays the number of requests, number of requests with mismatches,
-//       and enough of the data so that the operator can tell it's working.
-//
-#include <Wire.h>

-// BREADBOARD SETUP:
-// Arduino Uno R3 (D18/SDA) = I2C SDA 
-//     connect to SDA on slave with external pull-up (~4.7K)
-// Arduino Uno R3 (D19/SCL) = I2C SCL 
-//     connect to SCL on slave with external pull-up (~4.7K)
-// Arduino Uno R3 (D2)
-//     connect to !RST on slave
-//     Can alternatively connect !RST on slave to the Ardiuno "!RESET" pin
