Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es>
 | 
						|
 | 
						|
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 videodev
 | 
						|
insmod i2c scan=1 i2c_debug=0 verbose=0
 | 
						|
insmod tuner type=1 debug=0
 | 
						|
insmod bttv  pll=1 radio=1 card=17
