 Posted: Sun Jul 27, 2008 12:37 pm Post subject: lirc isn't working |
 |
|
[EDITED]
Hi,
I cannot get lirc to work. I have a leadtek remote control which came with my tv capture card, it generates event under /dev/input/eventX, but I cannot get lirc, irw, or irrecord to recognise any of the events.
I compiled lirc with the devinput device, but there is no /dev/lirc0 or /dev/lirc/0 device, only a /dev/lircd device? I'm not sure whether this is supposed to happen.
Also I cannot find where the debugging events from lirc are logged. There doesn't seem to be anything stored under /var/log/ to help my try and diagnose the problem.
How can I get lirc set up with my remote? The remote partially works without lirc, but there are some buttons which have a scan code greater than 255, and hence cannot be mapped to a keycode, hence I need lirc to make full use of all the buttons.

Also won't compile with the devinput module. I am going to try modify the ebuild and comment out the kernel 2.6.26 patch sense in this case were not running 2.6.26 kernel, and see if that makes a difference or not.

Some progress. I've managed to successfully build the serial module against my kernel (2.6.25-gentoo-r7).
I tried the 0.8.3 ebuild which works for some reason.
ebuild
| Code: | | ebuild lirc-0.8.3.ebuild merge |
The lirc_serial module is in my lib/modules path but I can't load it because it says the device or resource is busy. I'm guessing this explains why the remote was partially working without lirc, there is already an in-built kernel module which is using the port.
The problem is I have a whole bunch of modules compiled for the realtek DVT1000-T (cx88) video capture card, but I don't know which ones I need to remove to disable the in-build kernel support for this remote.

taking the 2.6.26 patch out of the ebuild also worked.

kg4ojl, did you have any luck with the devinput module after removing the patch? I also tried modifying the lirc-0.8.3-r2.ebuild to remove the epatch line, but after recompiling lirc still doesn't work on the /dev/input/event4 (ir remote) device.
I used a configuration file for my remote from the lirc website, but irw reports no button events.
I can't even figure out where lirc stores its log file, or how to turn on any useful debugging information, starting lircd manually with the -L switch just tells me it's an unrecognised option. Kind of strange considering it's listed in the man page and should allow me to specify a location for the log file.
I also tried running irrecord on my event device. This is the kind of output I get with lirc-0.8.2-r2. Interestingly with 0.8.3-r2 compiled I just get a full stop after every button press, but I end up getting the same message about no gap found.

Hold down an arbitrary button.

.irrecord: gap not found, can't continue
irrecord: closing '/dev/input/event4'

Always ends with gap not found. Even if I hold the same button for the entire time.
kg4ojl, would you be able to show me your conf.d/lircd file so I can compare it with mine. What kernel are you using? vanilla or gentoo-sources?
Any help would be awesome
lirc is one f****d piece of software

holy crap it works. I just used the lirc.conf file from here, which states it's for use with the linux input layer http://linux.bytesex.org/v4l2/faq.html#lircd . Previously I was using the config file someone generated for my remote.
All the keys are correctly mapped, I'm interested how it maps the keys properly given it's a generic devinput config file? How does it know what the buttons on my remote are?
Anyway, I suppose the next step is getting the button mapping into mythtv. |
