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