Examples

This example performs an ultrasonic range sample and then converts the sample from a timing into a measurement in millimetres.

UltraSound Test

Downloadable macro reference

	WaitForEcho
Waits until the echo has been received from the Ping macro allowing you to perform your own timing.
- VOID	Return

	MeasureDistance
Converts a micro second time from the ultrasonic range sensor and returns the range in mm, cm or inches.
- UINT	TimeDelay
Microsecond reading from Ultrasound module
- BYTE	Scale
0=MM / 1=CM / 2=Inch
- UINT	Return

	Ping
Performs a transmit ping allowing you to monitor the incoming signal and perform your own timings maybe using a rising edge interrupt and a timer.
- VOID	Return

	SampleSensor
Sends out an ultrasonic ping and times how long it takes to receive the echo. Returns the time in microseconds. Performs the timing using software so depending on the speed of the micro will be an approximation. For better results use the Ping macro.
- UINT	Return

Property reference

	Properties
	Time Measurement
Controls how the sensors ultrasonic ping is timed, Either using single microsecond delays or using timer hardware. On slower devices e.g. PIC it is advisable to use the Timer method.
	Timer
Timer Peripheral to use to monitor the passage of time.
	Connections
	Control Pin
Pin connected to the emitter of the sensor.
	Simulations
	Discrete Distance
Simulation range used to determine if the sense pin is active or not.
