| 2 | Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es> |

| 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. |

| 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 |

| 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 |
