AioSetDemoAoStartExtTrigger

Function

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

Format

Ret = AioSetDemoAoStartExtTrigger ( 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.
18261	Pointer to Data is NULL
28260	The value of Data is outside the designated range of the device being used
28261	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 Output Start by calling AioGetDemoAoStartExtTrigger function.

And also, you can confirm the current AO start condition by calling AioGetAoStartTrigger function.
Please indicate "Rising edge" / "Falling edge" by calling AioSetAoStarTrigger function before you use this function for Analog Output.

Example

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

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