# Heliox communication protocol

## Basic data structure

The following table describes the bit pattern for a successful communication with heliox devices.

|       0-15        |    16-22     |        23         |         24-31         | 32-(32+8*x) |
| :---------------: | :----------: | :---------------: | :-------------------: | :---------: |
| Magic Number (HX) | Message Type | Parity Bit (even) | Data Length (x Bytes) |    Data     |

## Message Types

| Code | Purpose              |
| ---- | -------------------- |
| 0x0  | Light Data           |
| 0x1  | Control Signal       |
| 0x2  | Status Messages      |
| 0x3  | Confirmation Message |
| 0x4  | Debug Info           |

### Light Data

- 1-Byte-block per lamp: 0-255
- Index of lamp determinded by order

### Control Signal

- Index Byte + [ **t** <sub>oggle</sub> | **i** <sub>ncrease</sub> | **d** <sub>decrease</sub> ]
- on
- off
