• Ports read & write
• Registers read & write

Usage

Unlike most Arduino library, no default instance is created when the library is included. It's up to you to create one with the appropriate chip I2C address.

#include <Arduino.h>
#include <MCP23017.h>

MCP23017 mcp = MCP23017(0x24);

Additionaly, you can specify the Wire instance to use as a second argument. For instance MCP23017(0x24, Wire1).
See included examples for furher usage.
