Using I2C and ATtiny85 with Adafruit I2C / SPI LCD Backpack

	/*
	Demonstration sketch for Adafruit LCD backpack
	using MCP23008 I2C expander
	Uses the ATTiny 85 (replaces Trinket below)

	The circuit:
	* 5V to Arduino 5V pin
	* GND to Arduino GND pin
	* Display i2c backpack CLK to Trinket GPIO #2 (Arduino pin 2/attiny85 pin 7)
	* Display i2c backpack DAT to Trinket GPIO #0 (Arduino pin 0/attiny85 pin 5)
