LevelCrossingDetector

Detect a threshold crossing on any of the channels in the incoming multi-channel datastream and emits an event in response.

Input port

port name	data type	slots	description
data	MultiChannelData <double>	1	None

Output port

port name	data type	slots	description
events	EventData	1	A stream of events.

Options

port name	data type	default	description
threshold	double	0.0	Threshold (in data units) that needs to be crossed.
event	string	threshold_crossing	The event to emit when the input signal crosses the threshold.
post detect block	unsigned int	2	refractory period after threshold crossing detection (in number of samples )
upslope	bool;	True	Either detect upward (true) or downward (false) threshold crossings.
