In our 2.6.24-34-fitpc2 kernel lirc module present under drivers/input/lirc and appropriate device node is /dev/lirc0.
To enable lirc just follow the manual http://fit-pc2.com/wiki/index.php?title ... _in_Ubuntu

Code: Select all

sudo irrecord -d /dev/lirc0 -f /etc/lirc/your_remote_name.conf

Has anyone gotten an apple remote (A1156) to work with fit-PC2? The strange thing is that I can fit-PC2 to pick up the buttons with irrecord but it fails to show any buttons being pushed when using irw. Any idea? If you got it to work can you post your lircd.conf? I've tried several different ones posted on numerous websites.

Thanks!

[Denis]

Try to run

Code: Select all

sudo xmode2 -d /dev/lirc0

and press buttons on your remote. You should see waveforms of IR signals. Ensure that you have same waveform while pressing on same button, that signals for all buttons have same length, may be you will see something unusual. If you do not have xmode2 - it`s in lirc-x package.

Hi Denis,

First off, thanks for you help. I can see the frequency but I don't understand how this helps me with lircd. The frequencies seem to be the same. The only thing that differs is how long I hold down the button for. Holding it longer shows a longer frequency obviously. I've attached an image displaying this.

Does this mean the remote will not work with irw? My goal is to get the remote to work with XBMC.

[Denis]

Xmode picture is fine, it means that your remote is sending appropriate signals, kernel driver is capable to decode them. Here are things that can be verified:

1. While recording with irrecord do you receive "Signal length is 39" messages in dialog? If not - start irrecord again. You should press remote buttons about 1 sec, not release them immediately.

2. Check if /etc/lirc/your_remote_name.conf was created properly and contains button`s names and their raw_codes.

3. Don`t forget to copy your_remote_name.conf to /etc/lircd.conf before testing with irw

Code: Select all

sudo cp /etc/lirc/your_remote_name.conf /etc/lircd.conf
sudo /etc/init.d/lirc restart
irw

Hi Denis I have tried your steps. I actually followed your walkthrough you posted [1]. Still not working though. Have you tried with an apple remote or did you try with some other generic remote?

[Denis]

I have tried several remotes, even some buttons of air conditioner controller give good signal (like in picture you have sent).

Let`s debug step by step.
1. Do you receive "Signal length is 39" messages in irrecord dialog?
2. /etc/lirc/your_remote_name.conf contains button`s names and their raw_codes?
3. /etc/lircd.conf and /etc/lirc/your_remote_name.conf are the same files?

Sorry for the delay in reply. I'm still working on this. I will try to get you some postings once I get out of work! Thanks Denis for being patient!
