-// ---------------------------------
-// Stress test program/example for TinyWireS I2C library.
-// Run this slave program on the Attiny.
-// Run the other master program on the Arduino Uno R3.
-// ---------------------------------
-// // Written by Scott Hartog, 2/6/2016, to stress test the TinyWireS library.
-// https://github.com/rambo/TinyWire
-//
-// This project uses the Tiny85 as an I2C slave.
-//
-// The slave program using TinyWireS, running on a Attiny85, receives
-// N bytes of random data in a single receiveEvent() callback and
-// stores that data in a global buffer. It then responds the first requestEvent()
-// callback with that same data. The requestEvent() callback overwrites the data
-// buffer with zeros after responding so it will only respond correctly to the
-// first requestEvent() callback after each receiveEvent() callback. Subsequent
-// requestEvent() will respond with 0xff for all data bytes.
-//
-//
-// SETUP:
-// AtTiny Pin 5 (PB0/SDA) = I2C SDA 
-//     connect to SDA on master with external pull-up (~4.7K)
-// AtTiny Pin 7 (PB0/SCL) = I2C SCL 
-//     connect to SCL on master with external pull-up (~4.7K)
-// AtTiny Pin 1 (PB5/!RST)
-//     connect to reset on master (or just pull-up)
-//
-// Please see credits and usage for usiTwiSlave and TinyWireS in the .h files of 
-// those libraries.
