Detailed Description

Here you'll find the Arduino code used to interface with the SX1509 I2C 16 I/O expander.

There are functions to take advantage of everything the SX1509 provides - input/output setting, writing pins high/low, reading the input value of pins, LED driver utilities (blink, breath, pwm), and keypad engine utilities.

Development environment specifics: IDE: Arduino 1.6.5 Hardware Platform: Arduino Uno SX1509 Breakout Version: v2.0

This code is beerware; if you see me (or any other SparkFun employee) at the local, and you've found our code helpful, please buy us a round!

Distributed as-is; no warranty is given.
