Ok, I tried lmhelper in XP, and....

It seems to work when I learn then transmit. i wonder if i need to
collect anything from those transmissions(i see some ir code pronto
format), but can that be used with lirc?

for instance, channel up is

0000 0048 0000 0011 0017 0164 0017 00A2 0017 00A2 0017 00A2 0017 0062
0017 00A2 0017 0062 0017 00A2 0017 00A2 0017 00A2 0017 00A2 0017 00A2
0017 00A2 0017 00A2 0017 00A2 0017 00A2 0017 00A1

what do i need to take from that and put in lircd.conf for up button?
thx

Looks like I had to use raw codes from irrecord instead of the old codes to get the remote working.

Following the instructions, it all went wrong at the beginning (after compiling and modprobing the kernel modules:

I plugged the device in after loading the requested kernel modules:

irrecord -l test.conf

That's why the patch is not integrated. (learnmode)

Be prepared for the irsend twice bug !

Thanks to all the posts here, and the previous work by others, I have my usb-uirt working under linux using 0.7.1 patched in raw mode.
I can both send and receive, but only with certain remotes. Some remotes I have don't appear to want to learn in raw mode, and I can't get learning in non-raw mode working at all.

Meanwhile, I've seen all the posts here and on lirc mailing list archives regarding the possibility of including the usb-uirt as a fully integrated patch into the official source if/when it's cleared up.

I'd be interested in doing this work, but since it's likely to take a while ( as I have a busy life and a demanding day job ), I wanted to gauge the level of interest ( I can achieve my own selfish aims much more easily by just hacking the source unmercilessly )

Ideally, I'd like to combine raw and non-raw modes into a single operating mode similar to what the USB-UIRT does under Windows, i.e. for transmit, raw data is used ( as it has to be ) but for receive, the predigested 6 byte code is used as the basis of a match.

This however will require a more extensive patch to the source tree, and again I'm not sure if it's worth it.

Any comments welcome.


I also have a number of technical queries which might best be answered in an lirc forum, but which I'm posting here in case anyone

[mrmailer]

I am interested, however, I do not think chirstoph will implement usb-uirt patch into cvs, because he belives uirt2_raw is close enough.

you should email him, lirc@bartelmus.de, and he will explain what is necessary.

Has anyone got their USB-UIRT to work under Fedora Core 6? I'm trying to follow Jarad Wilson's MythTV How-To at

http://wilsonet.com/mythtv/fcmyth.php

and he doesn't cover this. This thread is interesting but I haven't seen my answer yet. I'm running lirc 0.8.2, which should have USB-UIRT support in it.

[mrmailer]

yes, mine works fine

/etc/sysconfig/lirc
should contain
# Options to lircd
LIRCD_OPTIONS="-H uirt2_raw -d /dev/ttyUSB0"

[abreuma]

That didn't seem to help me. Here's what I did before making your change:

Per the Jarod Wilson MythTV how-to I did this:

# yum -y install lirc-kmdl-$KVER
# yum -y install lirc

I edited /etc/modprobe.conf to add this line, which was an educated guess:

alias char-major-61 lirc_usb-uirt2_raw

I picked up the "lirc_usb-uirt2_raw" by googling but have no idea if it's correct.

To get the drivers automatically loaded at boot time I did this:

# cd /etc/sysconfig/modules/
# wget --no-check-certificate https://svn.wilsonet.com/svn/mythtvology/trunk/lirc.modules
# chmod +x lirc.modules

Next I tried to start lirc:

# /sbin/service lircd start

I didn't get any message at all. When I look in /var/log/messages I don't see anything about lirc. So I went ahead and tried to test it and got an error:

$ /usr/bin/irw
connect: No such file or directory

I rebooted and nothing seemed to change.

When I went searching for lirc modules I see these and don't see one that looks like it's for the USB-UIRT.

I may need to go to the lirc list for help. I suspect right now that the lirc stuff I got from atrpms.net may not have usb-uirt support or that I'm missing some things in the modprobe.conf file.

Mark.

Is there a header file for hw_uirt2usb_raw.c? I don't see it on extracting lirc-0.7.1.tar.bz2.

I am getting the following compiler error:
hw_uirt2usb_raw.c:87: error: ‘LIRC_CAN_REC_LEARN’ undeclared here (not in a function)
hw_uirt2usb_raw.c:147: error: ‘LIRC_AUX_GET_FREQ’ undeclared (first use in this function)
hw_uirt2usb_raw.c:165: error: ‘LIRC_MODE_LEARN’ undeclared (first use in this function)
hw_uirt2usb_raw.c:250: error: ‘LIRC_MODE_LEARN’ undeclared (first use in this function)

Thanks,
Bibhu
