Class Pi1WireThDemo

java.lang.Object

de.weAut.demos.Pi1WireThDemo

All Implemented Interfaces:

ComVar, PiUtil, PiVals

public class Pi1WireThDemo
extends Object
implements PiUtil

Demo (Test) of using a 1-wire thermometer on Raspberry PI with Java.

On a Raspberry Pi with initialised 1-wire interface this program reads a thermometer device DS28B20 or alike.
Hint: The 1 in the class name is for 1wire not for Pi1.
Run by:

    java  de.weAut.demos.Pi1WireThDemo thermometerID 
  

Example:

    0123456789x12345
    java  de.weAut.demos.Pi1WireThDemo 28-02049245dde6 
  

To use a Raspberry GPIO pin as 1wire interface this interface and its driver have to be initialised; see the publication Raspberry for remote services.

Hint: Contrary to the pigpiod based Java IO programs, like BlinkOnPi and TestOnPi, this Java program would work only, when run on the Pi in question. TestOnPi etc. work also when run on another machine.
