LIRC not connecting with pypilot_hat

[drbarritt]

Hi, I am trying to get an IR remote control connected to my Pypilot.  the IR side seems to be working OK connected to GPIO 4 (as least I get pulse/space data when I run Mode2 that seems to make sense) and I have set up the lircd.conf file, but when I run pypilot_hat i get:

pi@openplotter:~/.pypilot $ pypilot_hat
hat start 1285.498098519

hat import done 1285.527343561

Any ideas?

There are a lot of different versions.. I support 2 different versions but maybe not what you have installed.

What does "pip3 freeze" show?

I don't even see lirc.

What if you just run python3 and type:
>> import lirc

or

>> import pylirc

Sean, lircd is running as a service, but not lirc:

Unit lirc.service could not be found.

I tried your suggested commands, but get the same error that pypilot_hat generates:

[seandepagnier]

it is obvious then that your python "lirc" module is broken if you cannot import it

can you pip3 install pylirc? or put a new version somehow?

[drbarritt]

Hi Sean, after a lot of fiddling around and running apt fix-broken, I have got lirc installed correctly and now I am getting a response on the hat webpage (33333).
Many thanks for all your help.

I spoke too soon! It worked once but then I was back with

failed to load lirc No module named '_client'
no lirc available No module named 'pylirc'

lirc is working fine. When I run irw I see the correct keys for each button press on my remote.

I found some info on the web (https://github.com/project-owner/Peppy.doc/wiki/Pylirc) and installed pylirc

pypilot_hat then showed

failed to load lirc No module named '_client'
have old lirc for remote control

plus an error about a missing lircrc config file so I added an lircrc.conf file in /etc/lirc/lircrc. I believe this maps the outputs from lirc to strings for the application program to use.

begin
prog = pypilot_hat
remote = NEC (this is the name of my remote in lircd.conf)
button = One (this is the first button on my remote as defined in lircd.conf)
repeat = 0
delay = 0
config = One (I think this is the string that gets sent to pypilot_hat)
end

I am not sure I have the format of this correct but it removed the error when running pypilot_hat.

Still no keys appearing on the hat webpage (33333)!

I also have a problem with hat.conf: I edited this to read "host": "pypilot", but every time I restart the Pi it reverts back to "host" : "none"

Any help would be much appreciated.

[seandepagnier]

Hmm strange that it revers back to none.   There is recently zeroconf support to detect the pypilot host location. Does the hat script connect to the server?

The .lircrc file is currently inside mydata.tgz in the tinypilot repository.  I attached here but you have to rename to .lircrc

[drbarritt]

The hat.conf file changing was down to me running 'pypilot_hat none'. I thought this would not run the LCD pop-up (I an running pypilot on the same pi as Open CPN).
Many thanks for the lircrc config file and I have modified this to suit my LIRC set up.
If I now run ircat and press buttons on the remote, it all works OK:

pi@openplotter:/etc/lirc/lircrc $ ircat -c /etc/lirc/lircrc/lircrc.conf pypilot
1
2
3
4
5
6
7
8
9

But still nothing appearing on 33333. I think I may abandon IR and use an RF remote wired directly to the pi GPIO.
Many thanks
David
