DioGetPulseMeasurementSetting

Function

Retrieves the pulse measurement settings for the specified channel.

Format

Ret = DioGetPulseMeasurementSetting( Id , ChNo , ChNum , MeasurementTarget , PulsePeriod )

Parameters

Id [ VB.NET： Short ] [ C, C++： short ] [ C#： short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved from DioInit.

ChNo [ VB.NET： Short ] [ C, C++： short * ] [ C#： out short ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the start address of the array that stores the channel numbers for which settings are to be retrieved.

ChNum [ VB.NET： Short ] [ C, C++： short ] [ C#： short ] [ Python: ctypes.c_short ]
Specify the number of channels specified in ChNo.

MeasurementTarget [ VB.NET： UShort ] [ C, C++： unsigned short * ] [ C#： out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Specify the start address of the array that stores the pulse measurement time settings.

PulsePeriod [ VB.NET： UShort ] [ C, C++： unsigned short * ] [ C#： out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Specify the start address of the array that stores the pulse measurement period. 

Return Value

Ret [ VB.NET： Integer ] [ C, C++： long ] [ C#： int ] [ Python: ctypes.c_long ]

Remarks

Retrieves the pulse measurement settings for the specified channel.

Example

Get the pulse measurement settings for channel 0 and channel 1.

VB.NET

Dim Ret As Integer
Dim ChNo(1) As Short
Dim MeasurementTarget(1) As UShort
Dim PulsePeriod(1) As UShort

ChNo(0) = 0
ChNo(1) = 1
Ret = DioGetPulseMeasurementSetting( Id , ChNo , 2 , MeasurementTarget , PulsePeriod )
 

C, C++

long Ret;
short ChNo[2];
unsigned short MeasurementTarget[2];
unsigned short PulsePeriod[2];

ChNo[0] = 0;
ChNo[1] = 1;
Ret = DioGetPulseMeasurementSetting( Id , &ChNo[0] , 2 , &MeasurementTarget[0] , &PulsePeriod[0] );
 

C#

int Ret;
short[] ChNo = new short[2];
ulong[] MeasurementTarget = new ushort[2];
ushort[] PulsePeriod = new ushort[2];

ChNo[0] = 0;
ChNo[1] = 1;
Ret = dio.GetPulseMeasurementSetting( Id , out ChNo , 2 , out MeasurementTarget , out PulsePeriod );
 

Python

Ret = ctypes.c_long()
ChNoType = ctypes.c_short * 2
ChNo = ChNoType()
MeasurementTargetType = ctypes.c_ushort * 2
MeasurementTarget = MeasurementTargetType()
PulsePeriodType = ctypes.c_ushort * 2
PulsePeriod = PulsePeriodType()

ChNo[0] = 0
ChNo[1] = 1
Ret.value = cdio.DioGetPulseMeasurementSetting( Id , ChNo , 2 , MeasurementTarget , PulsePeriod )
