RemoteSwitch library v2.3.0 (20121229) for Arduino 1.0

Made by Randy Simons http://randysimons.nl/



This library provides an easy class for Arduino, to send and receive signals

used by some common "old style" 433MHz remote control switches.



There are two styles of remote:

 - "old style", which uses switches or a dial to set the house code. Use this

   library.

 - "new style", which use a button on the receivers to "learn" a signal. Use

   the NewRemoteSwitch library instead.



See RemoteTransmitter.h and RemoteReceiver.h for details!



License: GPLv3. See ./RemoteSwitch/license.txt



Latest source and wiki: https://bitbucket.org/fuzzillogic/433mhzforarduino



Installation of library:

 - Make sure Arduino is closed

 - Copy the directory RemoteSwitch to the Arduino library directory (usually

   /libraries/)

   See http://arduino.cc/en/Guide/Libraries for detailed instructions.

 

Default installation sender & demo:

 - Connect tha data-in-pin of a 433MHz transmitter to digital pin 11. See 

   docs/hardware setup.jpg.

   (Note: your hardware may have a different pin configuration!)

 - Start Arduino, and open the example: File -> Examples -> RemoteSwitch ->

   LightShow

 - Alter addresses/devices to reflect your own setup. Otherwise nothing will

   happen.

 - Compile, upload and run!



Default installation receiver & demo:

 - Connect the data-out-pin of a 433MHz receiver to digital pin 2. See photo.

   (Note: your hardware may have a different pin configuration!)

 - Start Arduino, and open the example: File -> Examples -> RemoteSwitch ->

   ShowReceivedCode or ShowReceivedCodeNewKaku, depending on your remote.

 - Compile, upload and run

 - Open serial monitor in Arduino (115200 baud)

 - Press buttons on a 433MHz-remote, and watch the serial monitor

 

Notes:

 - These transmitters often use the PT2262 IC, or equivalent. For details about 

   the waveforms used by these remotes, the datasheet of the PT2262 is provided.

   Page 4 and 5 will be of most interest.



Changelog:

RemoteSwitch library v2.3.0 (20121229) for Arduino 1.0

 - Improved reception quality by filtering too short pulses.

 - Dropped pre-v1.0 Arduino support.

 - Added RemoteReceiver::deinit()



RemoteSwitch library v2.2.1 (20120314) for Arduino 0022/1.0

 - Fixed Elro code, it caused memory corruption.

 - Renamed old-style .pde files to new-style .ino



RemoteSwitch library v2.2.0 (20120213) for Arduino 0022/1.0

 - Added support for Elro switches (http://www.elro.eu/en/m/products/category/home_automation/home_control)

   (untested; I don't have these kind of devices)

 - Allowed the number of repeated signals transmitted by RemoteTransmitter to be

   changed.

 - By default, 16 instead of 8 repeats are sent.

 - Support for Arduino 1.0.

 - Added Datasheet PT2262, which (or equivalent) is often used in the transmitters.

 - RemoteReceiver::isReceiving timeout changed to 150ms; 100ms was too short.

 

RemoteSwitch library v2.1.1 (20110920) for Arduino 0022

 - Improved RemoteReceiver::isReceiving

 

RemoteSwitch library v2.1.0 (20110919) for Arduino 0022

 - Changed classnames from *Switch to *Transmitter

 - Added RemoteTransmitter::sendCode. See example "retransmitter".

 - RemoteReceiver::interruptHandler() is now public, for use with InterruptChain



RemoteSwitch library v2.0.0 (20100130) for Arduino 0017

 - Complete rewrite; can now receive and decode signals directly from

   the receiver's digital out.
