Detailed Description

the PWM function used to measure time during which the signal on the channel B as input is HI.

Constructor & Destructor Documentation

PWMgatedMeasure()

PWMgatedMeasure::PWMgatedMeasure	(	uint	pin_gate,
		uint	resolution_ns,
		uint	measure_duration_us )

Construct a new PWMgatedMeasure object.

Parameters

pin_gate	must be the channel B of a slice
resolution_ns	the minimum time slot as measure LSB. min = 8ns < step_ns < max = 256 * 8ns = ca 2us
measure_duration_us	the observation duration
