2 | Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es> | ||
3 | |||
4 | This card is basically the same as all the rest (Bt484A, Philips tuner), | ||
5 | the main difference is that they have attached a programmable attenuator to 3 | ||
6 | GPIO lines in order to give some volume control. They have also stuck an | ||
7 | infra-red remote control decoded on the board, I will add support for this | ||
8 | when I get time (it simple generates an interrupt for each key press, with | ||
9 | the key code is placed in the GPIO port). | ||
10 | |||
11 | I don't yet have any application to test the radio support. The tuner | ||
12 | frequency setting should work but it is possible that the audio multiplexer | ||
13 | is wrong. If it doesn't work, send me email. | ||
14 | |||

16 | - No Thanks to Leadtek they refused to answer any questions about their | ||
17 | hardware. The driver was written by visual inspection of the card. If you | ||
18 | use this driver, send an email insult to them, and tell them you won't | ||
19 | continue buying their hardware unless they support Linux. | ||
20 | |||
21 | - Little thanks to Princeton Technology Corp (http://www.princeton.com.tw) | ||
22 | who make the audio attenuator. Their publicly available data-sheet available | ||
23 | on their web site doesn't include the chip programming information! Hidden | ||
24 | on their server are the full data-sheets, but don't ask how I found it. | ||
25 | |||
26 | To use the driver I use the following options, the tuner and pll settings might | ||
27 | be different in your country | ||
