Class Pi1WireThDemo

java.lang.Object

de.weAut.tests.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 programme reads an thermometer device DS28B20 or alike.
Hint: The 1 in the class name is for 1wire not for Pi1.
Run by:

    java de.weAut.tests.Pi1WireThDemo thermometerID 
  

Example:

    0123456789x12345
    java de.weAut.tests.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.
