SparkFun SX1509 I/O Expander Example: digital out (digitalWrite)
|
||||
Jim Lindblom @ SparkFun Electronics
|
||||
Original Creation Date: September 21, 2015
|
||||
https://github.com/sparkfun/SparkFun_SX1509_Arduino_Library
|
||||
|
||||
This simple example demonstrates the SX1509's digital output
|
||||
functionality. Attach an LED to SX1509 IO 15, or just look at
|
||||
it with a multimeter. We're gonna blink it!
|
||||
|
||||
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!
