Version History & Bug list

The oIRPD1 Object is a Hardware Object that uses one I/O line to read the reflection state of an IR LED contained within an IR Proximity Detector.

It is used to detect if an object is in front of the sensor.

The following table lists the size and availability of the oIRPD1 Object.

	Object	Size	Description	A1	A2	B1	B2	C1
	oIRPD1	1 Byte	Reads a Lynxmotion IR Proximity Detector.	x	x	x	x	x

Operation:

The oIRPD1 Object monitors the I/O line specified by the IOLine property and updates the Position property with the current state. The I/O line is expected to be connected to the output of an IR Proximity Detector.

Properties:

The following table lists the properties of the oIRPD1 Object:

Property
Description

Position

A value that indicates the position of the item the detector sees.

Object Class: oLogic Value Range: 0 - 1

Data Type: Numeric Default Value: 0

Position Description

0 The IRPD does not see an object in front of it.

1 The IRPD sees an object in front of it.

IOLine

A value that specifies which I/O Line is connected to the Detector.

Object Class: oIOLine Value Range: 0 - 31

Data Type: Numeric Default Value: 0

Some I/O Lines have special purposes. Be sure to see oIOLine help file for details.

DIO

The I/O function object used to read the IRPD.

Object Class: oDIO1 Value Range: 0 - 1

Data Type: Numeric Default Value: 0

Address

Returns a pointer to the address of the oCounter Object instance.

Object Class: oAddress Value Range: 0 - 127

Data Type: Pointer (Read Only) Default Value: Address of Object

Examples:

In the following example, the oIRPD1 Object is used to read a Lynxmotion IRPD.

Visual Basic Syntax

C and Java Syntax

' This program reads a Lynxmotion 
' IRPD1 and displays the 
' results on I/O line 7

Dim A As New oIRPD1
Dim B As New oDIO1

Sub Main()
  A.IOLine = 9
  B.IOLine = 8
  B.Direction = cvOutput
  Do
    B.Value = A.Value
  Loop
End Sub

// This program reads a Lynxmotion
// IRPD1 and displays the
// results on I/O line 7

oIRPD1 A = New oIRPD1;
oDIO1 B = New oDIO1;

Void Main(Void){
  A.IOLine = 9;
  B.IOLine = 8;
  B.Direction = cvOutput;
  Do{
    B.Value = A.Value;
  } While (1);
}

Basic Syntax

' This program reads a Lynxmotion 
' IRPD1 and displays the 
' results on I/O line 7

A As oIRPD1(9)
B As oDIO1(8,cvOutput)
