I want to use an IR diod receiver. I installed lirc but when I write to terminal this code:

mode2 -d /dev/lirc0 

it says

mode2: could not get file information for /dev/lirc0
mode2: defauld_init(): No such file or directory

Where is the problem? Any idea?

    It may be because of device tree. See raspberrypi.stackexchange.com/questions/27073/…

  • thank you for your answer. It works, and I record my remote but now I'm writing "irw" but it doesn't show any thing about my buttons. May 18 '15 at 8:40
  • I think you should open a new question giving the details of the new problem.

It means there is a configuration issue.

To fix it:

  1. sudo vim /boot/config.txt
  2. add dtoverlay=lirc-rpi,gpio_in_pin=16 (change the pin to whatever you're using)
  3. reboot
  • Reboot was key.

  • The tutorial I was following left this crucial step off.
