Re: af9015: tuner id:179 not supported, please report!

2010-02-26 Thread Bert Massop
Using the previous patch, the compiler will complain about a missing
file (tda18218.h). Please use this updated version of the patch, also
made by Nikola.

Have fun with it, it's working fine here!

 Hello,

2009-12-20 Thread Bert Massop
Hi all,

Using some usb replay tools used for making the pvrusb2 work, I am
able to receive a working MPEG-TS stream, after snooping communication
in Windows. It's an ugly way to make things work, but now I'm able to
watch television in VLC. It's limited to 758MHz @ 8000KHz, thought,
because I only ran an usbsnoop for that specific frequency.

So right now I'm able to write the TS stream into a pipe / stdout /
file, but creating a (fixed frequency) driver for v4l is way too
complicated for me, at the moment. I don't really understand how the
v4l dvb drivers work, probably because I'm not really experienced in
doing so ;-) Currently, I'm trying to understand how frequency
selection works with this chip, and I'll be making a standalone
application to save the TS stream. Then, maybe someone else can write
a proper v4l driver for this chip.

Regards,
Bert

 The datasheet is missing too much important information needed to
 write a fully featured driver for the part, and I wouldn't recommend
 using a usbsnoop for this type of tuner, but be my guest and prove me
 wrong.

 You might be able to get it working, but you'll end up with tons of
 binary blobs hardcoded for each frequency, unless you use a
 programming guide.  Unfortunately, I don't have one that I can share
 :-/

 I think you would be much better off purchasing supported hardware, instead.

 Good luck, though...

  Hi Jan,
 
  As stated in the Ubuntuforums thread, there doesn't seem to be any support 
  for
  this chip at the moment. I don't know how hard it is to code support for a
  specific tuner, but I'm looking into that right now.
 
  Hopefully some more experienced coders will join in writing something 
  usable, as
  I don't think I will be able to do it myself.
 
  Please drop a message if anyone finds something useful.
 
  Best regards,
 
  Bert
 
 The TDA18218 is not currently supported under Linux.  I have the
 information needed to write a driver to support it, but I do not have
 any devices that use it, nor any interest (as of now) to write the
 driver on my own time.
 
 For me, it would not be very difficult to get this done, as I have
 done work to support a similar family of tuners -- TDA18271 /
 TDA18211.  The TDA18218 tuner is not supported by the current driver.
 
 In the past, I would have gone ahead and written a driver for the
 sheer enjoyment of doing so... but nowadays, I actually have other
 projects of a higher priority that need my attention instead.
 
 If, in the future, any commercial entity has interest in seeing this
 tuner silicon supported under Linux, they should contact me -- perhaps
 my desire to write this driver can be increased ;-)

   Hi Jan,
  
   As stated in the Ubuntuforums thread, there doesn't seem to be any 
   support for
   this chip at the moment. I don't know how hard it is to code support for a
   specific tuner, but I'm looking into that right now.
  
   Hopefully some more experienced coders will join in writing something 
   usable, as
   I don't think I will be able to do it myself.
  
   Please drop a message if anyone finds something useful.
  
   Best regards,
  
   Bert
 
  The TDA18218 is not currently supported under Linux.  I have the
  information needed to write a driver to support it, but I do not have
  any devices that use it, nor any interest (as of now) to write the
  driver on my own time.
 
  For me, it would not be very difficult to get this done, as I have
  done work to support a similar family of tuners -- TDA18271 /
  TDA18211.  The TDA18218 tuner is not supported by the current driver.
 
  In the past, I would have gone ahead and written a driver for the
  sheer enjoyment of doing so... but nowadays, I actually have other
  projects of a higher priority that need my attention instead.
 
  If, in the future, any commercial entity has interest in seeing this
  tuner silicon supported under Linux, they should contact me -- perhaps
  my desire to write this driver can be increased ;-)

 Hi Jan,

 The datasheet for the TDA18218 can be obtained from NXP:
 http://www.nxp.com/documents/data_sheet/TDA18218HN.pdf

 That's all the information I have at the moment, maybe Mike has some
 other information (like the Application Note mentioned in the
 datasheet, that claims to contain information on writing drivers, but
 cannot be found anywhere).

 Best regards,

 Bert

Took a quick look at that datasheet.  I would guess between that
datasheet and a usbsnoop, there is probably enough there to write a
driver that basically works for your particular hardware if you know
what you are doing.  The register map is abbreviated, but probably
good enough...
