Latest: added a version that compiles with 2.6.27 kernels.
Latest: if you are packaging this, see the note at the bottom as to why I don’t provide a simple patch.
Latest: added an updated version that compiles with 2.6.24 kernels, tested against 220.127.116.11
Latest: updated `firmware` to a later revision from hauppauge (743 codesets)
- This is not for the MCE version of the PVR-150. This includes a USB unit which does not work the same way as the normal PVR-150, use standard lirc (and lirc_mceusb) for that.
- Use a recent kernel (note: the ivtv drivers have been part of the mainline kernel for a good number of revisions so no external drivers are required — sorry, I don’t know off hand which revision they were merged in), or for older kernels install ivtv-0.4.2+ (from this page). Earlier versions of ivtv _are not supported_.
- Get the pre-patched lirc 0.8.5-CVS-pvr150 tarball. There are also earlier versions that can be found here, should you want them. The previous revision may be required for kernels < 2.6.27 (as it is untested on lower revisions -- in theory it should work)
- You need the dialog package installed to use the lirc configuration GUI, so install that (apt-get install dialog, yum install dialog, whatever is appropriate for your distribution).
- Unpack the patched lirc:
tar xfj lirc-0.8.3-CVS-pvr150-2.tar.bz2
i – Hauppauge PVR-150 TV card (note: _NOT_ ‘g – Hauppauge TV card’)
Save configuration & run configure
make && make install.
- IR blaster only: Now you need the ‘firmware’. This is a set of data blocks that correspond to those generated by the windows software. This goes in /usr/lib/hotplug/firmware on my debian system. Depending on your system this might also be /usr/local/lib/firmware, /lib/firmware or /lib/modules.
Note that the entire firmware is kept in memory (currently 300K) so this makes the driver quite large. (I have no plans to sort this out, memory is cheap).
- Check everything is working so far:
modprobe lirc_dev debug=1 && modprobe lirc_pvr150 debug=1
Check the syslog output. This should report something like:
Aug 28 02:09:11 soapbox kernel: lirc_pvr150: chip found with RX and TX
Aug 28 02:09:11 soapbox kernel: ivtv: i2c attach [client=Hauppauge PVR150 IR RX, ok]

Aug 28 02:09:11 soapbox kernel: lirc_dev: lirc_register_plugin: sample_rate: 0
Aug 28 02:09:11 soapbox udev: creating device node ‘/dev/lirc0′

Aug 28 02:09:11 soapbox kernel: lirc_pvr150: Hauppauge PVR-150 IR blaster: firmware version 1.3.0
This means that the driver has detected and initialised the IR blaster hardware — if you don’t see that then let me know.
- You need to configure lircd, and find out which codeset you are going to be using. The easiest way is to start with this configuration file which contains key definitions for everything in the database. Do not use other lirc configuration files for specific STBs — these simply will not work. The IR chip is only capable of sending those codes which are in the database.
- Start lircd. Note: if you are using a static /dev, you may need to make a device for lirc. If unsure, once you have verified that the module has been loaded ok, run
ls -l /dev/lirc*. If you don’t see a
/dev/lirc0 or similar, then try
mknod /dev/lirc0 c 61 0 if the steps below fail.
modprobe lirc_dev && modprobe lirc_pvr150 debug=1
- You can now check if the remote is working using
irw. Run this, and press buttons on the remote. You should see some output like
0000000000001795 00 Down Hauppauge_350.
- Next, for the ir blaster you need to work out which codeset to use, this is the tricky bit. For this I have send_power_new, a script that just sends the power command in every single codeset. You may find your codeset number listed here if you are lucky.
Firstly, check that you are seeing the IR blaster blink. If you don’t have blinking lights at this stage, your cable probably isn’t in the card properly (try wiggling it around), or it may be broken.
Next you need to stick the IR blaster on the IR receiver of box that you intend to control, being quite careful to position it correctly — it has a very short range (a few cm) and took me a couple of goes to get right. The best way to do this is to find the IR demodulator on the box — easiest with a torch. Note that this is _not_ the light that comes on when you press a button on the remote, they tend to look like this.
If you can’t get this to work, please try and check it against the Windows driver if possible. If your device will work with the windows driver but not my driver, then it’s a driver bug that I should be able to fix. If it does not work with the Windows driver either then your only options are to use a different IR blaster or bug hauppauge until they add support for the box you are trying to control. At that point, I can update my
- Once you know which codeset you want you can go and delete all of the rest from lircd.conf. They are named “XXX_key” so should be pretty easy to find. I also gave the keys standard names (0-9).
- To get mythtv to work, configure a channel change script for your device. There’s one here that should work out of the box if you
rename the number keys.
- If you’re happy, you can always send me beer money. If not, add comments at the bottom
That’s it, good luck!
The lirc distribution tarball is generated using `make dist-bzip2` which uses the gnu autotools to generate a configure script, and Makefile.in, etc. The contents of these generated files depends very much on the version of autotools that is installed; this varies from distribution to distribution. I don’t have the same auto* as the lirc maintainers, so producing a patch file against a distribution tarball makes a patch bigger than the original source archive. Hence I don’t bother; I just make a new dist bzip2 and drop it here.
I maintain the code by importing a current lirc CVS into a subversion repository hosted on this server. I tag each lirc import, generate a diff from the previous lirc import and apply it to my source tree, then port any fixes from lirc_i2c.c to lirc_pvr150.c, test, and generate a new .tar.bz2. To get the source tree you can do:
svn co http://svn.blushingpenguin.com/svn/trunk/3rdparty/lirc lirc
and you can get the changes I made to the CVS revision of lirc with:
svn diff http://svn.blushingpenguin.com/svn/vendor/lirc/current http://svn.blushingpenguin.com/svn/trunk/3rdparty/lirc
