Infrared remote control switch

History[ edit ] Inthe first example of wirelessly controlling at a distance was during a demonstration by the British physicist Oliver Lodgein which he made use of a Branly's coherer to make a mirror galvanometer move a beam of light when an electromagnetic wave was artificially generated. This was further refined by radio innovators Guglielmo Marconi and William Preeceat a demonstration that took place on December 12,at Toynbee Hall in London, in which they made a bell ring by pushing a button in a box that was not connected by any wires. Patent, named Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles, which he publicly demonstrated by radio-controlling a boat during an electrical exhibition at Madison Square Garden. Tesla called his boat a "teleautomaton".

Configuration guide About this guide This guide tries to describe the basic configuration steps for commonly used hardware. Recent Linux kernels have built-in support for IR remotes. Using that, pressing an up-arrow on the remote works the same way as pressing the up-arrow on a keyboard.

This is a modern "just works" solution. On the other hand, LIRC is an old style linux application which can be tweaked to do almost anything, but is tricky to setup. So, why would you use LIRC? Infrared remote control switch might have a remote which is supported by LIRC but not the kernel.

You might be on a non-Linux platform supporting lirc e.

You might have an application which is more or less designed to use LIRC. Handling input to multiple program is also easier with lirc You might want to send IR signals to other devices IR blasting. So, while the kernel built-in handling works out of the box in many cases, there are still scenarios when LIRC is the right tool.

The default configuration From 0. This should work out of the box with the following limitations: There must be exactly one capture device supported by the kernel The remote s used must be supported by the kernel. There is no need to do IR blasting i.

The easy way to check is to try the remotes without lircd running. If it works this way, it should also work using lircd. This should list a single entry rc0.

If you want to use the default configuration you should start and enable the lircd service and possibly define lircrc files for your applications. The project began with support for home-brew receivers and transmitters for the serial port and later support for similar hardware for the parallel port was added.

At that time the focus of the project was to provide an infrared solution that was both very cheap and easy to assemble. There is some more info on this in Appendix 11 Current versions of LIRC now support many more commercially available solutions. As a starter, it can use all devices supported by the kernel.

Drivers for even more hardware are likely to appear in the future. If you are a programmer who wants to maintain such a driver you are welcome to join the project.

You need to decide on a general approach. Using the LIRC data requires application support. Support for LIRC is common in typical linux htpc applications like mythtv, kodi and vlc; of course also LIRC applications like irexec, lircmd and irpty supports this.

Unless there is reason to use lirc above this is probably the way to go. If you need to use lirc, there are two cases depending on if your remote is supported by the kernel or not. See lircd-uinput 8 The lirc configuration consists of several files described in Appendix There are some tools to aid in the configuration listed in programs overview Basic setup flow remote air gap !

Use irw 1 to debug. The remote generates an IR or perhaps RF signal.

Data from the kernel is then caught by LIRC using a lircd driver. In the next step, lircd converts the kernel data from the lirc driver to key symbols using the lircd.

This flow is configured in four points: The kernel driver occasionally needs to be configured using modprobe 1 or udev 7. See Configuring the kernel lircd needs to know which driver and often also kernel device to use. This is described in Determine driver and device.

To convert IR pulse data to key symbols lircd needs a lircd. Creating this is done either by using the linux input layer or an lirc driver. Converting key symbols to application strings is done using a lircrc config file. This is created according to Convert the key symbols to application strings.
