11 | /* protocol (from usblogging and the SDK: |
12 | * | |
13 | * Always 7 bytes bulk message(s) for controlling | |
14 | * | |
15 | * First byte describes the command. Reads are 2 consecutive transfer (as always). | |
16 | * | |
17 | * General structure: | |
18 | * | |
19 | * write or first message of a read: | |
20 | * <cmdbyte> VV <len> B0 B1 B2 B3 | |
21 | * | |
22 | * second message of a read | |
23 | * <cmdbyte> VV <len> R0 R1 R2 R3 | |
24 | * | |
25 | * whereas 0 < len <= 4 | |
26 | * | |
27 | * I2C address is stored somewhere inside the device. | |
28 | * | |
29 | * 0x01 read from EEPROM | |
30 | * VV = offset; B* = 0; R* = value(s) | |
31 | * | |
32 | * 0x02 read register of the COFDM | |
33 | * VV = register; B* = 0; R* = value(s) | |
34 | * | |
35 | * 0x05 write register of the COFDM | |
36 | * VV = register; B* = value(s); | |
37 | * | |
38 | * 0x06 write to the tuner (only for NXT6000) | |
39 | * VV = 0; B* = PLL data; len = 4; | |
40 | * | |
41 | * 0x03 read remote control | |
42 | * VV = 0; B* = 0; len = 4; R* = key | |
43 | * | |
44 | * 0x07 write to the remote (don't know why one should this, resetting ?) | |
45 | * VV = 0; B* = key; len = 4; | |
46 | * | |
47 | * 0x08 write remote type | |

50 | * 0x09 write device init | |
