AioSetAiClockEdge

Function

Sets the timing of external clock input.

Format

Ret = AioSetAiClockEdge ( Id , AiClockEdge )

Parameters

Id [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Specifies the ID retrieved from AioInit function.

AiClockEdge [ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short ]
Sets the timing of external input from the following range.

0

External input falling edge

1

External input rising edge

Return value

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

Return values

Content

0

Normality completion

7

Execute AioResetDevice function because the device has recovered from standby mode

10001

Invalid Id was specified
Use the Id retrieved from AioInit to specify the Id in this function.

10002

AIO driver can't be called
At first, perform AioInit function.

12310

The value of AiClockEdge is outside the designated range of the function

20001

This function can't be used by this device

20002

Can not use while by another device works
To use this function, analog input operation must be stopped.

20003

Can not use because another process is using the device
When another process is using the device, all functions except for those that support multi-process can not be performed.

Initial value

External input falling edge is used for all devices. *

Remarks

If the external clock is set by AioSetAiClockType function, it is possible to set external trigger falling edge or rising edge.
When internal clock is being used, the setting by this function is invalid.

This function cannot be used on devices without the analog input function.
If the device is in operation, the function cannot be performed.

DEMO DEVICE do not support external clock function.

Remarks

* In case of using ADA16-8/2(LPCI)L and AD16-16(LPCI)L
For these devices, whether AioSetAiClockEdge function can be used or not depends on manufacturer's serial version.
This function returns 20001 error as unsupported version of hardware is being used.

Example

Uses the external input rising edge as the clock.

VB.NET

Dim Ret As Integer
Ret = AioSetAiClockEdge ( Id , 1 )
 

C, C++

long Ret;
Ret = AioSetAiClockEdge ( Id , 1 );
 

C#

int Ret;
Ret = aio.SetAiClockEdge ( Id , 1 );
 

Python

Ret = ctypes.c_long()
Ret.value = caio.AioSetAiClockEdge ( Id , 1 )
