Obviously, if a certain program support LIRC natively that’s the way to go! through irxevent, which is a LIRC native client, that send the key-pressed event to the software as if were pressed on the keyboard. natively, with the aims of a configuration file (~/.lircrc) that map key-pressed events to specific actions.The upper layer software can manage LIRC events in two different ways: Lircd translates the received signal in a specific key-pressed event with the aims of its configuration file (/etc/nf) and notifies this event via socket (/dev/lircd) and/or TCP/IP (port 8765). In the Apple iMac specific case, the IR receiver is connected to the USB bus and supported by the stock kernel through the usbhid module the received signals are accessible through /dev/usb/hiddevX (blue block’s of the figure above).ĭepending on the specific receiver driver, the infrared signals, captured by the receiver, are passed to the lirc daemon (lircd) on a specific /dev file. the software clients that translate IR commands to specific actionsĪ detailed diagram of the different components is represented in the figure below:.the lirc daemon (lircd) which decodes the driver IR commands.a kernel driver that manage the hardware receiver.LIRC decodes IR signals received by the device drivers and provides the information to the higher software level. Since it seems from here that the first method is the most recent and the way to go, I choose that one. device managed by the input module) and translating kernel’s key events directly to useful symbolic names, without any further configuration necessary (i.e. Inputlirc is a small daemon that acts like a LIRC daemon, reading /dev/input/eventX (i.e. input device (event) – using the appleir kernel module, the receiver acts as a USB input device (as a small USB 6 keys keyboard) LIRC is no necessary here, inputlirc can handle the remote events generated by the kernel.HID device (raw) – usbhid manages the receiver and LIRC handles remote signals with the macmini driver.Linux offers mainly two different approaches to manage the Apple IR remote: In this post I’ll show how to configure the iMac Apple Remote to work in Linux: this will let us control our favorite media player (Totem, Xine, MPlayer, Rhythmbox) comfortably sitting on our sofà □įrom a hardware point of view, the Apple iMac IR receiver is connected via the USB bus. LIRC is the Linux Infrared Remote Control framework: it’s widely used to control the computer with an IR remote (connected either to a USB or a Serial Port) and to send IR commands, if the hardware supports this feature – unfortunately mine don’t □ To start the daemon selected, click the left mouse button over the icon and it will change, indicating activation.Infrared in Linux: LIRC JPosted by idebian in Debian, GNU/Linux, Hardware. Then you must add it to a notification panel of your environment.Ĭlicking the right mouse button on the icon you can choose which daemon will run: irexec, irxevent or both. To install it, just run the commands as super user: # wget -O ir_b However, the switching of daemon was not a practical task, then I decided to create a GNOME Applet specific to work with LIRC, the ir-switcher (other projects). In my case, I always active the irexec for multimedia and and irxevent for presentations. Being the first block responsible for simulating the play key on the keyboard, and the second the F5 key. Both represent actions that must be performed when PLAY button is used. The first block is activated when the daemon irexec is running, while the second is activated when the irxevent is running. Below are shown two blocks of this configuration file. The configuration file is located in /etc/lirc/lirc/lircrc and contains the mapping of commands to be executed for each action of the control. In Ubuntu, it can be installed, along with utilities, from the command as super user: # aptitude -y install lirc lirc-x xautomationĪfter the installation, simply create the configuration file to start using the remote control. In order to recognize and active the infrared commands and execute the actions for each key, we will use the package LIRC (Linux Infrared Remote Control). Set up the infrared remote control on a MacBook with Ubuntu.
