1 2 Support for the Leadtek WinView 601 TV/FM by Jon Tombs <firstname.lastname@example.org> 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 15 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 28 29 insmod videodev 30 insmod i2c scan=1 i2c_debug=0 verbose=0 31 insmod tuner type=1 debug=0 32 insmod bttv pll=1 radio=1 card=17
