Several of the pre-defined remotes uses non-standard key symbols. There you should find something like:. Furthermore, since ir-keytable finds the device you know that the driver is part of the rc subsystem.

In some cases any file can be used if it conforms to some limitation. This might become necessary if the running kernel is different from the one used when packaging the lirc files. Verify the results using irw 1 in another window.

This should work out of the box with the following limitations:. This means that you should pay attention that your TV card is detected correctly by bttv, as can be checked using dmesg 1. Note that this is not persistent, you need to do this after each boot. Niput, only a single LIRC transmitter is required as long as each of the tuners have mutually exclusive remote codes, and the LIRC transmitter can placed in the line of sight of all tuners’ IR receivers.

The generated file will look like excerpt! When using remotes which are not infrared, the corresponding driver is not affected by the methods above. LIRC ijput be run together with the kernel in different ways.


LIRC is a software package that gives your computer the ability to send and receive infra-red remote control signals when combined with appropriate hardware. Setup the first device according to the main flow in this document, then add the second as documented below.

Setting up LIRC on the RaspberryPi –

Please check out these diagrams for information and schematics about how to wire everything up: There are two ways inpuf run as a regular user. The standard symbols a.

Imput Linux kernels have built-in support for IR remotes. Normally there will be a different remote type for receiver and blaster functions. Each instance must have unique –device–output and –pidfile options. Please enable JavaScript to view the comments powered by Disqus.

Linux input layer driver

If you need to use an IR blaster to change channels on a set top box you may have to use LIRC, since there is no built in support in Linux for those. This needs to be resolved using the setserial 1 tool. If your distribution has an outdated version of LIRC or one that has the wrong options built in you may need to download the source from lirc.

If you have a standard IR remote which is recognized by the kernel you can find how it’s registered as rc Check that all buttons generate output when testing.


LIRC – Linux Infrared Remote Control

Run these two commands to stop lircd and start outputting raw data from the IR receiver: You need to decide on a general approach. At the end of that post I had decided to rebuild the project on a RaspberryPi. Creating udev rules is a large topic.

If this is not an issue, document system changes according to local policy. Before you start down the LIRC path validate whether your remote will work in some way as a keyboard emulator.

Another example is lirc serial drivers which conflicts with the kernel default tty driver. You cannot transmit through a receiver or lirrc through a transmitter. Doing so you can use your desktop tools to control the service. In some cases there is more info in the driver documentation. For more information please see the lkrc Ubuntu Launchpad bug This means that the number of configurations has some limits, otherwise it would take too long time.
