Ultrasonic component

This board has both an ultrasonic transmitter and receiver. The transmitter is driven by an on-board 40KHz oscillator which is enabled by the host microprocessor. The receiving sensor signal is amplified and provided as an analogue signal to be processed by a single channel ADC of the microprocessor. By measuring the time delay between enabling a transmit pulse and receiving an echo the distance of objects in a range of around 3cm to 3m can be determined.

EBM019 Example

Macro reference

GetDistance

	GetDistance
Sends a pulse and processes the echo. Returns a object distance in cm
- UINT	Return

Initialise

	Initialise
Setup the device. This sets the control output to logic 0
- VOID	Return

SetDelayTime

	SetDelayTime
Set the delay time before sampling for the echo, in microseconds
- UINT	delay
delay time in microseconds
- VOID	Return

SetDetectionValue

	SetDetectionValue
Set the delta value for echo detection
- BYTE	value
trigger point for echo detection
- VOID	Return

SetPulseWidth

	SetPulseWidth
Set the output pulse width, in microsecond (0-255uS)
- BYTE	pulse
width of pulse in microseconds
- VOID	Return

Property reference

	Properties
	Output Pulse Pin
Pin used for controlling the output pulse
	Echo ADC channel
ADC channel used to monitor the echo
	Pulse Width (uS)
Output ultrasonic pulse width in microseconds
	Read Delay (uS)
Time delay in microseconds before sampling for echo
	Pulse Detection Value
Detection ADC delta trigger value A lower value is more sensitive
