Connect IR Receiver to Raspberry Pi
Vcc -> 3V
GND -> GND
Vout -> GPIO 18
Load LIRC module on boot.
Edit /boot/config.txt
Add line
dtoverlay=lirc-rpi***For new kernel***
dtoverlay=gpio-ir
or (change GPIO pin in for IR Receiver)
dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=18
*** For new kernel ***
dtoverlay=gpio-ir,gpio_pin=18,gpio_pull=up

irrecord - application for recording IR-codes for usage with lirc Copyright (C) 1998,1999 Christoph Bartelmus(lirc@bartelmus.de) This program will record the signals from your remote control and create a config file for lircd. A proper config file for lircd is maybe the most vital part of this package, so you should invest some time to create a working config file. Although I put a good deal of effort in this program it is often not possible to automatically recognize all features of a remote control. Often short-comings of the receiver hardware make it nearly impossible. If you have problems to create a config file READ THE DOCUMENTATION of this package, especially section "Adding new remote controls" for how to get help. If there already is a remote control of the same brand available at http://www.lirc.org/remotes/ you might also want to try using such a remote as a template. The config files already contain all parameters of the protocol used by remotes of a certain brand and knowing these parameters makes the job of this program much easier. There are also template files for the most common protocols available in the remotes/generic/ directory of the source distribution of this package. You can use a template files by providing the path of the file as command line parameter. Please send the finished config files toso that I can make them available to others. Don't forget to put all information that you can get about the remote control in the header of the file. Press RETURN to continue. Now start pressing buttons on your remote control. It is very important that you press many different buttons and hold them down for approximately one second. Each button should generate at least one dot but in no case more than ten dots of output. Don't stop pressing buttons until two lines of dots (2x80) have been generated. Press RETURN now to start recording. ................................................................................ Found const length: 107201 Please keep on pressing buttons like described above. ................................................................................ Space/pulse encoded remote control found. Signal length is 67. Found possible header: 8951 4451 Found trail pulse: 572 Found repeat code: 8961 2214 Signals are space encoded. Signal length is 32 Now enter the names for the buttons. Please enter the name for the next button (press to finish recording) KEY_POWER Now hold down button "KEY_POWER". Please enter the name for the next button (press to finish recording) KEY_1 Now hold down button "KEY_1". Please enter the name for the next button (press to finish recording) KEY_2 Now hold down button "KEY_2". Please enter the name for the next button (press to finish recording) KEY_3 Now hold down button "KEY_3". Please enter the name for the next button (press to finish recording) ...
