mailra · [SOLVED] IR, no output from IRW and not work mailra July 17, 2017 at 6:19 PM

Thank you for your help. Before trying gpio-ir, i did try to correct lircd.conf and you was absolutely correct - generated file is invalid because of 0x00000000, so i removed these zeros sequences.

Code

begin remote
  name  ml3
  bits           32
  flags SPACE_ENC|CONST_LENGTH
  eps            30
  aeps          100
  header       9017  4487
  one           579  1666
  zero          579   550
  ptrail        584
  repeat       9020  2234
  gap          108065
  toggle_bit_mask 0x0
  frequency    38000
      begin codes
          KEY_MUTE                 0x00FF00FF
          KEY_VOLUMEUP             0x00FF8877
          KEY_VOLUMEDOWN           0x00FF08F7
      end codes
end remote

Also just in case i have removed lircmap.xml which i have created desperately when was trying last time to solve that.

After reboot - it magically works! So all problem was in lircd.conf generated file.

Thanks for help and support.

Hello everyone,

i am stuck with configuring IR remote (from Microlab Pro 3) can't get it work. Here is there full story - what was done:

1. Added - "dtoverlay=lirc-rpi,gpio_in_pin=25" to config.txt (as i use iqaudio pi-dac+ which is mapped IR pin to 25)

2. dmesg | grep lirc

Code

[    3.576349] lirc_dev: IR Remote Control driver registered, major 244
[    3.620614] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
[    4.551568] lirc_rpi: auto-detected active low receiver on GPIO pin 25
[    4.551766] lirc_rpi lirc_rpi: lirc_dev: driver lirc_rpi registered at minor = 0

[    4.899723] input: eventlircd as /devices/virtual/input/input3

3. killall lircd

4. mode2 -d /dev/lirc0

Code

So IR - receiver works fine.

5. Tried this: ir-keytable -p LIRC from guide: Guide To lirc rpi GPIO Receiver - LibreELEC

Code

Couldn't find any node at /sys/class/rc/rc*.

So just skipped.

6. irrecord /storage/.config/lircd.conf

Created for me ml3.lircd.conf so i have just copied and renamed it to lircd.conf

Code

begin remote

  name  ml3
  bits           32
  flags SPACE_ENC|CONST_LENGTH
  eps            30
  aeps          100

  header       9017  4487
  one           579  1666
  zero          579   550
  ptrail        584
  repeat       9020  2234
  gap          108065
  toggle_bit_mask 0x0
  frequency    38000

      begin codes
          KEY_MUTE                 0x00FF00FF 0x00000000
          KEY_VOLUMEUP             0x00FF8877 0x00000000
          KEY_VOLUMEDOWN           0x00FF08F7 0x00000000
      end codes

end remote

7. Reboot, and that's it - configured buttons do not work, irw - shows nothing.

8. Tried Added/Created Lircmap.xml added to ~/.kodi/userdata

Code

<lircmap>
<remote device="ml3">
                <volumeplus>KEY_VOLUMEUP</volumeplus>
                <volumeminus>KEY_VOLUMEDOWN</volumeminus>
                <mute>KEY_MUTE</mute>
</remote>
</lircmap>

No help.

Almost forgot:

RP3 (IR - Infrared Receiver (TSOP38238)), LE:8.0.2 (Kernel 4.9.29), Build: Kodi 17.3, Git 147cec4, (25.05.2017)

Will be appreciated for any help.
