The PCTV 340e is one of those unfortunate situations that I (Devin Heitmueller) personally take alot of criticism over. About two years ago I bootstrapped the driver, got it working with the hardware, but then never got around to cleaning up the code enough to get it upstream. This has resulted in the HG tree… Read More

HVR-1150/1120 IR support
Things continue to be busy here at KernelLabs. This week submitted a patch upstream which results in the IR receiver support starting to work on the HVR-1150 and HVR-1120 boards. This was something that several people had been mentioning to me as an issue over the last nine months. Thanks go out to Fernando Laudares… Read More
dib0700 IR fixes
In response to ongoing issues with the IR support for dib0700 and firmware 1.20, I spent most of yesterday refactoring the code. When firmware 1.20 was introduced, the dib0700 switched from a polling model using a USB control message, to the messages being delivered on a USB bulk pipe. The code I originally added would… Read More
PCTV 340e feedback
We received a good bit of feedback in the last 24 hours from users trying out the PCTV 340e driver, and I am happy to say that 100% of it has been positive. There were a few issues with new users not familiar with compiling v4l-dvb from source code, but everybody who has tried it… Read More
Christmas present to users: PCTV 340e Support!
I finally got the new DVB generator up and running, and spent the afternoon debugging the PCTV 340e. The digital support is now working! http://kernellabs.com/hg/~dheitmueller/pctv-340e-2/ As always, there are a bunch of caveats: The testing as of this point has been *very* limited. I have basically confirmed that tuning works with tzap/mplayer with 8MHz DVB-T…. Read More
PCTV 340e: Help Wanted
So I am now at the point where I am ready to start debugging signal lock. This is the phase in the project where all the code is written but has never actually been tested/debugged. My situation however is complicated by the fact that I do not actually have access to a DVB-T signal currently…. Read More
PCTV 340e Update
This weekend I spent some cycles working on the xc4000 driver and the surrounding code required for the PCTV 340e. I think I now have the PLL properly programmed, and I worked around the i2c clock stretching deficiencies in the dib0700. We’re quickly approaching the point where I’m ready to start testing for signal lock…. Read More
PCTV 340e and em28xx VBI support
Did some more work on the PCTV 340e. After talking to Rainer over at PCTV as well as Patrick Boettcher, it seems pretty clear that this is some sort of issue related to the dib0700 not properly handling the xc4000’s clock stretching. Pretty annoying though, since the last dib0700 device I worked on required me… Read More
PCTV 340e work continues….
Spent another evening working on the PCTV 340e. I refactored a bunch of the xc4000 code so the standard firmware and scode blobs now successfully load. For the moment the video standard is left at the default and the driver is hard-coded to 8Mhz DVB-T. Also started going through the dib7000p configuration, which is needed… Read More
PCTV 340e scode and standard loading
Spent most of the afternoon working on my tool which generates the firmware images for the xc4000. Pulled in the code from the existing xc2028/3028 driver to load the scode/std firmware into the chip, but it seems to fail the i2c write with the DTV8 standard. Probably some issue with switching between direct/indirect mode. Once… Read More
