Help please Pi-zero and IR

Hairybiker

OK after a long break I am trying to get rune audio to play on my Zero.
I have the 0.4beta image installed and working fine.
I have managed to get the lcd working
But I cannot for the life of me get the ir working.

I know it works 'cause I have used the same zero and ir in another project. (Debian based)

I have installed the lirc driver in the config.txt, added the lirc and lirc-utils packages but irrecord doesn't and mode2 says no lirc.

So a simple work through please. (I have already combed this board but there are bits and pieces and a load of pm's but no how to's.

When I get it working I will post a complete how to on adding an i2c Lcd and ir (based on Xplod's work with my code included)

Hi Hairybiker,

a bit more info about used hardware and the errors from mode2 would help.

I have installed the lirc driver in the config.txt

Please post the your config.txt (lirc part).

Name:   gpio-ir
Info:   Use GPIO pin as rc-core style infrared receiver input. The rc-core-
        based gpio_ir_recv driver maps received keys directly to a
        /dev/input/event* device, all decoding is done by the kernel - LIRC is
        not required! The key mapping and other decoding parameters can be
        configured by "ir-keytable" tool.
Load:   dtoverlay=gpio-ir,<param>=<val>
Params: gpio_pin                Input pin number. Default is 18.

        gpio_pull               Desired pull-up/down state (off, down, up)
                                Default is "down".

        rc-map-name             Default rc keymap (can also be changed by
                                ir-keytable), defaults to "rc-rc6-mce"

Name:   lirc-rpi
Info:   Configures lirc-rpi (Linux Infrared Remote Control for Raspberry Pi)
        Consult the module documentation for more details.
Load:   dtoverlay=lirc-rpi,<param>=<val>
Params: gpio_out_pin            GPIO for output (default "17")

        gpio_in_pin             GPIO for input (default "18")

        gpio_in_pull            Pull up/down/off on the input pin
                                (default "down")

        sense                   Override the IR receive auto-detection logic:
                                 "0" = force active-high
                                 "1" = force active-low
                                 "-1" = use auto-detection
                                (default "-1")

        softcarrier             Turn the software carrier "on" or "off"
                                (default "on")

        invert                  "on" = invert the output pin (default "off")

        debug                   "on" = enable additional debug messages
                                (default "off")

OK Pi zero,
ir diode connected to pin 18, 3v3 & gnd (as per THIS)
Had it working fine under openelec so I know it works.

config.txt
dtoverlay=lirc-rpi

Don't you know it. mode2 is working this morning! I did reboot yesterday but ...
OK will keep going a bit further.
EDIT:
OK didn't get much further. Lircd isn't starting.
I have copied over my lircd.conf from the openelec setup to /etc/lirc/lircd.conf.d/lircd.conf

Hi Hairybike,

Active: failed (Result: exit-code) since Thu 2017-02-09 10:54:56 GMT; 1s ago

You need to find the reason for this:

systemctl status lircd
journalctl -ex

OK I get:

Hi,

please enable journal:

systemctl unmask systemd-journald

Edit /etc/systemd/journald.conf

....
[Journal]
Storage=volatile
.....

Reboot.

You can read the journal with

journalctl

OK some further probing give this:

[root@runeaudio lirc]# lircd
Driver `lirc_rpi' not found or not loadable (wrong or missing -U/--plugindir?).
Use lirc-lsplugins(1) to list available drivers.

So it seems to be missing the lirc_rpi driver? Where do I get that?

Hi Hairybiker,

lirc and lirc-utils packages are installed?

pacman -Sy lirc lirc-utils

What is the output from:

lsmod

Maybe this will help

Yes I installed lirc & lirc-utils

No one?

kumowoon1025

Do you have both gpio-ir and lirc-rpi applied? (you shouldn't.)
