All Implemented Interfaces:

GpioProvider

public class ADS1015GpioProvider
extends ADS1x15GpioProvider
implements GpioProvider

This GPIO provider implements the TI ADS1015 analog to digital converter chip as native Pi4J GPIO pins. More information about the board can be found here: * http://www.ti.com/lit/ds/symlink/ads1015.pdf http://adafruit.com/datasheets/ads1015.pdf

The ADS1015 is connected via I2C connection to the Raspberry Pi and provides 2 GPIO pins that can be used for analog input pins.
