mode2 works too.

mode2 -d   /dev/lirc0

Pulse's and space's are being showed. Also I have configurated .conf correctly as been told in instructions.

irrecord -d /dev/lirc0 ~/lircd.conf
cp ~/lircd.conf /etc/lirc/lircd.conf

Problem is that irw does not work. It outputs nothing after pressing my remote controller. irsend command outputs nothing too (checked led with camera, does not work)

 irsend SEND_ONCE /etc/lirc/lircd.conf KEY_POWER

my /boot/config.txt:

dtparam=audio=on

# NOOBS Auto-generated Settings:
hdmi_force_hotplug=1
config_hdmi_boost=4
overscan_left=24
overscan_right=24
overscan_top=16
overscan_bottom=16
disable_overscan=0

dtoverlay=w1-gpio,gpiopin=4
dtoverlay=lirc-rpi,gpio_in_pin=22,gpio_out_pin=23

Any help or suggestions will be very big for me

********UPDATE*********

cat /sys/kernel/debug/gpio

prints

 GPIOs 0-53, platform/20200000.gpio, pinctrl-bcm2835:
 gpio-4   (w1                  ) in  hi
 gpio-16  (?                   ) out hi

Should it be a question-mark?

********UPDATE2********* Okey. Big changes. after Joan irw command now works. I have fresh generated lircd.conf file. now "irw" works and shows

root@raspberrypi:~# irw
0000000000000a81 00 KEY_POWER SONY
0000000000000a81 01 KEY_POWER SONY
0000000000000a81 02 KEY_POWER SONY

but

root@raspberrypi:~# irsend --device=/dev/lircd SEND_ONCE SONY KEY_POWER
root@raspberrypi:~# irsend --device=/dev/lircd SEND_ONCE SONY KEY_POWER
root@raspberrypi:~# irsend --device=/dev/lircd SEND_ONCE SONY KEY_POWER
root@raspberrypi:~#

does not work. What can I try now?

Answer 1

So my Pi was configured correctly. Problem was at wiring. Transistor on DIOD was accidentally to big ant no signal goes through. I hope my debugging will help to solve similiar problems. Thanks for your time
