- VID:PID - 0416:5020
- Product ID: LS32 Custm HID
- uses HID Protocoll
- 2 endpoints, uses endpoint 1 for data, all with report 0
- 64 byte paket size
Badge Protocol (Report #0)
Report size: 64 byte (rep_num+data[64])
Header (first report to send):
id[5]: "wang",0x00
byte: Brightness in 4 steps
byte: bit-coded: flash messages
byte: bit-coded: border messages
byte: Message 0 speed and effect
byte: Message 1 speed and effect
byte: Message 2 speed and effect
byte: Message 3 speed and effect

word: Message 0 length (big endian)
word: Message 1 length (big endian)
word: Message 2 length (big endian)
word: Message 3 length (big endian)
word: Message 4 length (big endian)
word: Message 5 length (big endian)
word: Message 6 length (big endian)
word: Message 7 length (big endian)
The length counts in the 8x11 characters/elements.
Brightness coding:
0x00xx0000
^^ ----- 0: 100%, 1: 75%, 2: 50%, 3: 25%
Brightness setting is global for all messages.
Flash & Border effect coding:
0bxxxxxxxx
^ - 1: Message 1 flash/border, 0: no effect
^ -- 1: Message 2 flash/border, 0: no effect
...
Per bit setting for the messages.
Speed & effect/pattern coding:
0bxxxxnnnn
^^^^ - Effect number [0..8], see enum effects
^^^^ ----- Scrolling/effect speed [1..8]
| Effect | Number |
|---|---|
| left | 0 |
| right | 1 |
| up | 2 |
| down | 3 |
| freeze | 4 |
| animation | 5 |
| snow | 6 |
| volume | 7 |
| laser | 8 |
Data frames/messages
Data follows (second to nth report to send, all use Report #0) char[11]: characters as bitmasks (8x11), stuffed together to fill the reports.
Display:
0 {8bit} | 11 | 22 | ...
1 {8bit} | 12 | 23 | ...
...
10 {8bit} | 21 | 32 | ...
Up to 6 'chars' are displayed directly on the display. Here the last 4 rows/bits are ignored. On fewer 'chars', the content is centered on the display. On more than 6 'chars', the 6th is fully used, depending on the chosen effect.
This behavior is important if bitmaps should be displayed.
