Package jpigpio.packet

Class Rf433tx

java.lang.Object
jpigpio.packet.Rf433tx
public class Rf433tx
extends java.lang.Object
Class implementing 433 MHz transmitter (e.g. FS1000A) using pigpiod daemon. Specific protocol (high/low signal duration, datagram/message length etc. can be cofigured by passing different Protocol object to the constructor of this class.

Work is based on Robert Tidey LightwaveRF code https://github.com/roberttidey/LightwaveRF Example usage: see Test_Rf433Tx
