If you just find something like this you have a device which isn’t an IR device in this case an RF remote:. Note that this is not persistent, you need to do this after each boot. If you need to use lirc, there are two cases depending on if your remote is supported by the kernel or not. The next step is to convert the symbols to configure the systemd service. Even if you have an IR device, you might see something like this if the kernel sees it as a keyboard rather than a remote.

Setting Up LIRC on the RaspberryPi

The –repeat option should only be used if no other program or udev rule is automatically setting up key repeat parameters. I highly recommend referring to the schematics I linked to above. For more information please see the the Ubuntu Launchpad bug I chose the RaspberryPi because I wanted a single device to host a web server in addition to being able to handle the IR transmitting and receiving.

There ibput some lirf to find or create such a file. The only situation where the described procedure will not work is when you have two devices that both use a kernel driver that can only handle one device at once like e.

Using the same one for both will only cause frustration, since your commands to MythTV will be received also by the cable box and the commands from the backend will be seen by the frontend. Which looks more or less like my remote control.


The irw tool connects to the lircd socket and displays any recognized IR signals detected by the driver. If you find your configuration file contains RAW codes then you should try again.

Home Questions Tags Users Unanswered. Use the irw program to see whether LIRC and your remote are working before going any further. Obviously, this saves some work.

Usually the default kernel serial port driver grabs all ports it auto-detects as soon as it is loaded and the LIRC modules won’t be able to use any of them. The LIRC project began as an attempt to create drivers for home-brew hardware. You may find that you are getting double hits for some of your buttons example: In some cases any file can be used if it conforms to some limitation.

Normally there will be a different remote type for receiver and blaster functions. I have completed a soldered circuit prototype, complete with a full parts list and high resolution build pictures. Some devices are created as accessible only by root. If this works, then your hardware, driver and lirc. Here were the commands that I ran to generate a remote configuration file: Furthermore, since ir-keytable finds the device you know that the driver is part of the rc subsystem.


The lircd output socket argument is an optional path to the lircd output socket. See Running as a regular user.

Setting up LIRC on the RaspberryPi –

Some links to build such:. You can also create your own lircd. This is described in appendix 2. Thus lircd-uinput needs to run as root unless these permissions are changed.

You should replace all non-standard definitions with standard key symbols where it’s possible. I was, however, able to build a functional prototype: If it works this way, it should also work using lircd.

For details of the available options see User Manual: Make sure to share your remote with the lirc community by sending the config to lirc bartelmus.

Using this, you can bind remote buttons to any command you can run. Most distributions include LIRC packages, but you may have to compile it yourself if you wish to use certain features that the distribution packagers did not include. Also you may have to power on the cable box.
