These should be made accessible using udev rules. Each instance must have unique –device , –output and –pidfile options. Otherwise, try to change the protocol see the ir-keytable manpage. This will print garbage on the terminal when remote buttons are pressed if it is the correct device. Also you may have to power on the cable box.

This means that you should pay attention that your TV card is detected correctly by bttv, as can be checked using dmesg 1. Use this to see the results of clients connecting to lircd daemon.

This will create a new service called liirc. Usually the default kernel serial port driver grabs all ports it auto-detects as soon as it is loaded and inpug LIRC modules won’t be able to use any of them. However, there are some instances where unique control codes aren’t possible for example, you have two Comcast Cable boxes so you can record two shows at once. The first way is to run irexec as a system daemon. Not all devices are recognized by ir-keytable, though.

In some cases any file can be used if it conforms to some limitation.

Setting Up LIRC on the RaspberryPi

So I copied the contents of lirc. You can [ use udev ] to ensure the input device corresponding to your remote has a name that does not change across reboots.


The first platform I started with was an Arduino Uno. The standard symbols a. Obviously you should not use a remote that goes with another appliance in the same room as your MythTV setup, because the remote button presses will be picked ijput by both MythTV and your other device.

Normally you could use this feature as-is. This way inpuf security problems since running arbitrary commands and scripts as root is generally a bad idea.

When using remotes which are not infrared, the corresponding driver is not affected by the methods above. Common values are ‘Any’ meaning that any file from the website could be used or inpuy meaning that the driver requires a specific config file. This might become necessary if the running kernel is different from the one used when packaging the lirc files.

In any case, the repeat events generated by the kernel can be tweaked using the –repeat option. To do this, you need to define udev rules. You must be running on the latest firmware and OS for this guide to work. Since this depends on how the device is connected, you lose if you disconnect the licr and reconnect it to another socket.

Setting up LIRC on the RaspberryPi –

Sign up using Email and Password. In some cases there is more llrc in the driver documentation. This document was created by man2htmlusing the manual pages. Drivers for even more hardware are likely to appear in the future. There are two ways to run as a regular user. Here you can see the device’s name: If you find your configuration file contains RAW codes then you should try again.


In normal operation the idea of the remote is to operate across the living room. When doing so, it will try to match input with each configuration until there is inpuf match.

Some of the downloaded lircd. This is done using modprobe, using command line parameters to modprobe 1 or adding files to the lirx. The drawback is that since it runs as a regular user, it might run into permission problems e. Combining both of these options might give unexpected results. Doing so you can use your desktop tools to control the service.

The driver list gives some hints on the usage for each driver.
