12 | * Always 7 bytes bulk message(s) for controlling | |

14 | * First byte describes the command. Reads are 2 consecutive transfer (as always). | |

16 | * General structure: | |
17 | * | |
18 | * write or first message of a read: | |
19 | * <cmdbyte> VV <len> B0 B1 B2 B3 | |
20 | * | |
21 | * second message of a read | |
22 | * <cmdbyte> VV <len> R0 R1 R2 R3 | |
23 | * | |
24 | * whereas 0 < len <= 4 | |
25 | * | |
26 | * I2C address is stored somewhere inside the device. | |
27 | * | |
28 | * 0x01 read from EEPROM | |
29 | * VV = offset; B* = 0; R* = value(s) | |
