2Support for the Leadtek WinView 601 TV/FM by Jon Tombs <>
   4This card is basically the same as all the rest (Bt484A, Philips tuner),
   5the main difference is that they have attached a programmable attenuator to 3
   6GPIO lines in order to give some volume control. They have also stuck an
   7infra-red remote control decoded on the board, I will add support for this
   8when I get time (it simple generates an interrupt for each key press, with
   9the key code is placed in the GPIO port).
  11I don't yet have any application to test the radio support. The tuner
  12frequency setting should work but it is possible that the audio multiplexer
  13is wrong. If it doesn't work, send me email.
  16- No Thanks to Leadtek they refused to answer any questions about their
  17hardware. The driver was written by visual inspection of the card. If you
  18use this driver, send an email insult to them, and tell them you won't
  19continue buying their hardware unless they support Linux.
  21- Little thanks to Princeton Technology Corp (
  22who make the audio attenuator. Their publicly available data-sheet available
  23on their web site doesn't include the chip programming information! Hidden
  24on their server are the full data-sheets, but don't ask how I found it.
  26To use the driver I use the following options, the tuner and pll settings might
  27be different in your country
  29insmod videodev
  30insmod i2c scan=1 i2c_debug=0 verbose=0
  31insmod tuner type=1 debug=0
  32insmod bttv  pll=1 radio=1 card=17
