In my last entry about universal remote the subject was treated with the Arduino. Integration into FHEM for home control is made more difficult, has to that communication between the devices takes place. Instead of a comprehensive protocol for data communication, the universal remote control is directly related to the Raspberry Pi implemented. In contrast to the Arduino, the GPIO ports are unfortunately operated with 3.3V instead of 5V.
The hardware is similar to the Arduino directly connected to the GPIO ports. Here, the different availability of ports should be considered when the Raspberry Pi models. In this article, the terminal GPIO pin 22 is provided for the IR receiver and the GPIO pin 23 for the IR transmitter.
Instead of a small library for IR detection and sending LIRC is used. "LIRC is the abbreviation for Linux Infrared Remote Control. This is a program for Linux that allows you can put commands from IR remotes in program instructions. What is needed is for only one infrared receiver. [...] To to decode the signals from remote controls correctly, you need a configuration file that is tailored to the respective remote control. you can either create this yourself, or download an appropriate file from the Internet. " (Source: Wikipedia )
Installation and setup on the Raspberry Pi there is an interesting article which serves for the following calls as a base. Installing LIRC done simply by apt-get.
$ sudo apt-get install lirc
To load the required modules manually and to test them there modprobe. In the lirc_rpi the correct assignment of the GPIO ports must be observed!
$ sudo modprobe lirc_dev $ sudo modprobe lirc_rpi gpio_in_pin=22 gpio_out_pin=23
UPDATE: 27/04/2015: Immediately the module is no longer on / etc / modules GpsDrive but over /boot/config.txt
$ sudo vi /boot/config.txt dtoverlay=lirc-rpi,gpio_out_pin=23,gpio_in_pin=22
The modules are loaded at startup, this must be entered in the modules file.
$ sudo vi /etc/modules lirc_dev lirc_rpi gpio_in_pin=22 gpio_out_pin=23
The lirc device can be determined by ls in the dev directory.
$ ls -l /dev/lir* crw-rw---T 1 root video 248, 0 Jan 5 12:16 /dev/lirc0
In the config file of the LIRC device and the modules must be entered.
$ sudo vi /etc/lirc/hardware.conf # -u --uinput generate Linux input events LIRCD_ARGS="--uinput" DRIVER="default" DEVICE="/dev/lirc0" MODULES="lirc_rpi"
Restarting the daemon.
$ sudo /etc/init.d/lirc restart
The receiver can be tested to determine its basic functionality by using the LIRC daemon gestommt and by mode2 the RAW output is viewed by the device. Pressing any key on a IR remote control should turn space and pule entries appear.
$ sudo /etc/init.d/lirc stop $ mode2 -d /dev/lirc0 space 1622 pulse 667 space 1573 pulse 675
The initial lircd.conf is empty. It can be used either existing configuration files, unless you record your own which are for the remote control, or.
$ cat /etc/lirc/lircd.conf
In the SourceForce remote project many remotes have already been recorded. Also provides with LIRC own files.
$ ls /usr/share/lirc/remotes/
When YAMAHA RAX9 remote control, there is already a file in the project.
$ mkdir lirc $ cd lirc $ wget http://lirc.sourceforge.net/remotes/yamaha/RAX9 $ sudo cp RAX9 /etc/lirc/lircd.conf
The program irw the inputs of the remote control can be read.
$ irw 000000005ea158a7 03 vol+ rax9 000000005ea1e817 00 aux rax9
If there is no output appear the daemon testweise be started in the foreground. Errors or warnings are displayed Possibly here.
$ sudo /etc/init.d/lirc stop $ sudo lircd --nodaemon -H devinput
You can send faxes using irsend.
$ irsend SEND_ONCE rax9 aux
The daemon is stopped and a separate file for each remote is irrecord with the program recorded.
$ sudo /etc/init.d/lirc stop
For SAMSUNG - AA59-00743A remote control a possible call would be as follows.
$ sudo irrecord -H default -d /dev/lirc0 AA59-00743A
The program guides the user through the process of recording. The list of key codes helps correct assignment. After picking up the generated file is copied as new /etc/lirc/lircd.conf and restart the daemon. Agent irw as described above can be found in the pressed keys.
$ sudo cp AA59-00743A.conf /etc/lirc/lircd.conf $ sudo /etc/init.d/lirc restart $ irw 00000000e0e040bf 00 KEY_POWER Samsung_AA59-00743A $ irsend SEND_ONCE Samsung_AA59-00743A KEY_POWER
The same is for all other remote control performed (here, the LG - AKB73615701).
sudo irrecord -H default -d /dev/lirc0 AKB73615701
At the end of all the configuration files into one file and used as new lircd.conf.
$ cat *.conf > lircd.conf $ sudo cp lircd.conf /etc/lirc/lircd.conf
or
cat AKB73615701.conf AA59-00743A.conf RAX9 > lircd.conf sudo cp lircd.conf /etc/lirc/lircd.conf
With the module Remotcontrol a floorplan can be created. On the Floor Plan, all keys are stored. The Samsung remote control may be defined as follows.
define RC_TV remotecontrol attr RC_TV rc_iconpath icons/remotecontrol attr RC_TV rc_iconprefix black_btn_ attr RC_TV room 1.0_Wohnzimmer attr RC_TV row00 KEY_POWER:POWEROFF,:blank,KEY_SELECT:SOURCE attr RC_TV row02 :blank,:blank,:blank attr RC_TV row03 KEY_1:1,KEY_2:2,KEY_3:3 attr RC_TV row04 KEY_4:4,KEY_5:5,KEY_6:6 attr RC_TV row05 KEY_7:7,KEY_8:8,KEY_9:9 attr RC_TV row06 :blank,KEY_0:0,KEY_REWIND:PRECH attr RC_TV row07 :blank,:blank,:blank attr RC_TV row08 KEY_VOLUMEUP:UP,KEY_MUTE:MUTE,KEY_CHANNELUP:CHUP attr RC_TV row09 KEY_VOLUMEDOWN:DOWN,:blank,KEY_CHANNELDOWN:CHDOWN attr RC_TV row10 KEY_MENU:MENU,:blank,KEY_PROGRAM:GUIDE attr RC_TV row11 :blank,:blank,:blank attr RC_TV row12 :blank,KEY_UP:UP,KEY_INFO:INFO attr RC_TV row13 KEY_LEFT:LEFT,KEY_ENTER:ENTER,KEY_RIGHT:RIGHT attr RC_TV row14 :blank,KEY_DOWN:DOWN,KEY_EXIT:EXIT define NRC_TV notify RC_TV {system("irsend SEND_ONCE Samsung_AA59-00743A $EVENT")}
The values and rc_iconpath rc_iconprefix define the path for the images. Agent rowXX the lines defined by the buttons. Each button is stored internally by EVENT: IMAGE. The notify treats the click of the button and sends the EVENT at irsend.

:( I'm nearing despair
've been looking all over the wets but find nothing to my problem.
Have a raspberry pi 2 and everything funzt actually up on irsend.
root@ir:~# irsend SEND_ONCE tvpanasonic KEY_1
irsend: command failed: SEND_ONCE tvpanasonic KEY_1
irsend: unknown remote: "tvpanasonic"
have constantly the message. Hopefully someone has an idea?

Hi, do you have an entry in the config file "begin remote" and "name tvpanasonic"?
