Help using MCP23017 Adafruit-MCP23017-Arduino-Library

/24/2016This interrupt example from the Adafruit MCP23017 library does not seem to work for me. It wont generate interrupts on the arduino and the LED pin does not flash. There does not seem to be many arduino libraries for MCP23017 at all - I have only found two, one of which does not have interrupt related functions.
