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).
