SparkFun SX1509 I/O Expander Example: blink output
|
|
Jim Lindblom @ SparkFun Electronics
|
|
Original Creation Date: September 21, 2015

|
https://github.com/sparkfun/SparkFun_SX1509_Arduino_Library
|
|
|
|
This example demonstrates the SX1509's set-it-and-forget-it
|
|
blink function. We'll set the pin up as an OUTPUT, and call
|
|
io.blink() all in setup(), then watch the LED blink by itself
|
|
in loop().
|
|
|
|
Hardware Hookup:
|
|
SX1509 Breakout ------ Arduino -------- Breadboard
|
|
GND -------------- GND
|
|
3V3 -------------- 3.3V
|
|
SDA ------------ SDA (A4)
|
|
SCL ------------ SCL (A5)
|
|
15 -------------------------------- LED+
|
|
LED- -/\/\/\- GND
|
|
330
|
|
|
|
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!
