AioSetDemoAiStartExtTrigger

Function

This is a function that sets the analog input start trigger of the demo device.

Format

Ret = AioSetDemoAiStartExtTrigger ( Id , Data )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the device ID retrieved from AioInit.

Data [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the data to be set.

0	OFF
1	ON

Return values

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
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.
18141	Pointer to Data is NULL
28140	The value of Data is outside the designated range of the device being used
28141	A driver inner error occurred

Remarks

This is a function dedicated to the demo device.

The initial value is 0 (OFF).
You can confirm the external trigger level for Analog Input Start by calling AioGetDemoAiStartExtTrigger function.

And also, you can confirm the current AI start condition by calling AioGetAiStartTrigger function.
Please indicate "Rising edge" / "Falling edge" by calling AioSetAiStarTrigger function before you use this function for Analog Input.

Example

Sets the analog input start trigger to 1 (high level).

C, C++	long Ret; Ret = AioSetDemoAiStartExtTrigger ( Id , 1 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSetDemoAiStartExtTrigger ( Id , 1 )
