Examples

This example performs an ultrasonic range sample using a hardware timer and then converts the sample from a timing into a measurement in millimetres, centimeters and inches.

Ultrasound Test

Macro reference

MeasureDistance

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

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

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


WaitForEcho

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


Property reference

Properties
Connections
Control Pin
Pin connected to the emitter of the sensor. 
Measurement
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 Properties
Timer
Timer Peripheral to use to monitor the passage of time. 
Simulation
Discrete Distance
Simulation range used to determine if the sense pin is active or not.
