Sending codewords from Arduino over RF-Transmitter

[frankkremer]

Hello,

I'm working on a new project and want to control wireless power switches from labview over an arduino. I bought a simple set of 3 switches with a remote control online.

Currently my Ardunino ist connected to relays which are connected to the remote control. This way each button on the control needs one relay.

There is a more elegant way. You could connect the arduino to the RF-Transmitter of the remote control and send the right codeword serially over a single one of the arduino outputs. Other people have already done this successfully with an Arduino.

The problem is that the pulse length is 360 microsencods. Is there a way to generate this with LabVIEW+Arduino Uno R3?

I hope you can help me and please say so if you need more information.

It sounds like you need to add a custom function to LIFA.  If you have working code for the Arduino, could you post the files as attachments?

I've found a couple of remote control hacks on the web. Many of them use this library: https://code.google.com/p/rc-switch/downloads/list

There is also a little bit of explanation on the site. The wiring looks like this: https://code.google.com/p/rc-switch/wiki/HowTo_Send?tm=6

My remote control uses an HX2262 encoder chip and is listed on the "List of known devices".
