i just started using lirc on raspberry 3. with

sudo apt-get install lirc

i put on the rpi, i changed the entries in 

modules
hardware.conf
config.txt

as stated in http://alexba.in/blog/2013/01/06/setting-up-lirc-on-the-raspberrypi/

but i dont get any in- and out-pins associated with lirc. these are my outputs:

uname -a

Linux raspberrypi 4.4.16-v7+ #899 SMP Thu Jul 28 12:40:33 BST 2016 armv7l GNU/Linux

cat /sys/kernel/debug/gpio

GPIOs 0-53, platform/3f200000.gpio, pinctrl-bcm2835:

GPIOs 100-101, platform/soc:virtgpio, brcmvirt-gpio, can sleep:
gpio-100 (                    |?                   ) out hi

sudo dmesg | grep lirc

[3.662057] lirc_dev: IR Remote Control driver registered, major 245 
[4.659023] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
[5.618718] lirc_rpi: auto-detected active high receiver on GPIO pin 18
[5.619407] lirc_rpi lirc_rpi: lirc_dev: driver lirc_rpi registered at minor = 0
[5.619411] lirc_rpi: driver registered!
  • i thought, the standard config would do me in and out on GPIO17 and 18. instead of it i've got only a virtual pin.
  • possible hint: i use a python-script on startup with GPIO-Usage (physical Buttons) - disabled on startup for now.
  • how to get "real" connections for lirc?

Ignore all those outdated instructions and UNDO any changes you made.

Add the following to /boot/config.txt and reboot.

dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=18

For general device tree help see /boot/overlays/README.

In future make sure you are using an up to date tutorial as things change quite quickly on the Pi.
