CLASS1.DATA
Representation for different general data types. Byte 0 is the data coding byte described here. Unit may not have meaning for some of the types and should be set to zero in that case.
VSCP_TYPE_DATA_GENERAL
General event.
VSCP_TYPE_DATA_IO
General I/O value. First data byte defines format.
Data byte | Description |
---|---|
0 | Data coding. |
1-7 | Data with format defined by byte 0. |
VSCP_TYPE_DATA_AD
General A/D value. First data byte defines format.
Data byte | Description |
---|---|
0 | Data coding. |
1-7 | Data with format defined by byte 0. |
VSCP_TYPE_DATA_DA
General D/A value. First data byte defines format.
Data byte | Description |
---|---|
0 | Data coding. |
1-7 | Data with format defined by byte 0. |
VSCP_TYPE_DATA_RELATIVE_STRENGTH
Relative strength.
Data byte | Description |
---|---|
0 | Data coding. |
1-7 | Data with format defined by byte 0. |
Code | Description |
---|---|
0 | Byte count = 2: Min = 0, Max = 255 Byte count = 3: Min = 0, Max = 65535 and so on... |
1 | db (decibel) |
2 | dbV (decibel volts) |
3 | Undefined |
Units for Level II are the same as for Level I for the first four units.
VSCP_TYPE_DATA_SIGNAL_LEVEL
Signal Level is a relative strength value that (as default) has its maximum at 100 and minimum at 0 interpreted as a percentage. For a digital transmission Signal Level it can be used to give an indication of the analogue signal and CLASS1.DATA, Type = 6, Signal Quality can be used to give an indication of the quality of the digital part as BER (Bit Error Ratio) for example.
Data byte | Description |

0 | (0-100) percentage. |
1 | Byte count = 2: Min = 0, Max = 255 Byte count = 3: Min = 0, Max = 65535 and so on... |
Units for Level II are the same as for Level I for the first four units.
VSCP_TYPE_DATA_SIGNAL_QUALITY
