MedianArray |
| Passes an entire buffer through the median buffer and spits out a filtered version of the data at the other end | |
 - VOID
|
Return |
|
|
Median |
| Passes a single value from a DSP buffer into the median buffer and spits out a median value at the other end | |
| - VOID
|
Return |
|
|
ReadAverageArray |
| Returns the average from the last "Decay" number of buffers. | |
 - UINT
|
Return |
|
|
ReadPeak |
| Returns the highest value from the last "Decay" number of index locations. | |
| [[File:]] - | Return |
|
|
ResetRecords |
| Allows the peak and trough to be reset back to default values. | |
| [[File:]] - | ResetPeak |
| [[File:]] - | ResetTrough |

|
Return |
|
|
GetReplyByte |
| Reads a single byte from the last reply. Each reply contains 4 bytes starting with the command code. | |
 - BYTE
|
Index |
| Range: 0-3 / 0=Command, 1=Feedback, 2=Data MSB, 3=Data LSB | |
| - BYTE
|
Return |

|
|
PlayTrack |
| Plays track from the selected folder. MP3 & Advert folder track numbers should be 4 characters long e.g. 0001 any name.mp3, Other folder track numbers should be 3 characters long e.g. 001 Any name.mp3, Root the Track played in placement order. | |
| - BYTE

| - VOID
|
Return |
|
|
ReadAnalogAsInt |
| Reads one of the analogue components as an Integer value | |
| - BYTE
|
Channel |
| 0 = LDR, 1 = POT | |
| [[File:]] - | Return |
|
|
RemapCharacter |

Properties |
|
Connect To |
| DSP component with output buffer to collect our data from. | |
|
Buffer Size |
| Number of individual elements the buffer can store, default 1. | |
|
Buffer Type |
| Sets the buffer data type. | |
|
Median Array Size |
| The number of values to combine together to create the median effect. Default 5. The higher the number the more immune to spikes the data will be. A larger array requires more processing to order. Minimum 3, maximum 255. | |
