USB cable:

Standard USB to miniUSB.

Protocol

TODO.

The device's LCD segments are layed out as follows:

  G  
   
C F
   
  B  
   
A E
   
  D  

To the left of each LCD digit there is another segment which represents a dot / decimal point (DP).

An LCD segment is represented in the protocol as follows:

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
DP A B C D E F G

Example: In the protocol a byte of 0x3F (0 0111111) represents the digit 9 on the LCD, where the decimal point is not displayed (bit 7 is not set). All other bits except for bit 6 (segment A, see above) are set (i.e. the LCD segment is displayed).
