public class MCP23017Pin
extends MCP23X17Pin

This GPIO provider implements the MCP23017 I2C GPIO expansion board as native Pi4J GPIO pins. More information about the board can be found here: * http://ww1.microchip.com/downloads/en/DeviceDoc/21952b.pdf http://learn.adafruit.com/mcp230xx-gpio-expander-on-the-raspberry-pi/overview

The MCP23017 is connected via I2C connection to the Raspberry Pi and provides 16 GPIO pins that can be used for either digital input or digital output pins.
