DIY I2C LCD Display With Inputs: 6 Steps - instructablescom
How to use Multiple mcp23017 chips with the adafruit mcp23017. h library. For example if the first chip is addressed as 0x20 and the IO number count is from 0 - 15 if I added and addressed another chip as 0x21 will that count go from 0 - 15 to 0 - 31. Ok, I've never used the mcp23017 with an arduino before but on the raspberry pi,

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.

MCP23017 I/O Port Expander Circuit with an Arduino Microcontroller. The MCP23017 I/O port expander circuit we will build with an Arduino microcontroller is shown below. and then turn it off. For example, if you wanted to blink an LED on pin 0, you would write, Wire. write(00000001), then maybe wait a half of second, so you would write, delay
