SparkFun SX1509 I/O Expander Example: clock 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 clock output
|
|
functionality. The OSC pins (OSCIO in the datasheet), can be
|
|
configured as either a clock input, clock output, or an
|
|
extra output!
|
|
|
|
Hardware Hookup:
|
|
SX1509 Breakout ------ Arduino
|
|
GND -------------- GND
|
|
3V3 -------------- 3.3V
|
|
SDA ------------ SDA (A4)
|
|
SCL ------------ SCL (A5)
|
|
OSC ------------- Check with a multimeter or o-scope
|
|
|
|
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!
