/dev/lirc0 does not exist

Question

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?

Answer 1

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
