AioSetAoStopTrigger


Function

Sets the conversion stop condition.

Format

Ret = AioSetAoStopTrigger ( Id , AoStopTrigger )

Parameters

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

AoStopTrigger [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the conversion stop condition from the following range. 
The available value differs by the device.

0

Stop conversion by the specified times

1

External trigger rising edge

2

External trigger falling edge

10

Event controller output

Return value

Ret [ C, C++ : long ] [ 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.

13260

The value of AoStopTrigger 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 output 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.

23260

The value of AoStopTrigger is outside the designated range of the device being used

Initial value

"Stop conversion by the specified times" for all devices

Remarks

When AoStopTrigger = 0 (Stop conversion by the specified times), the following operation is performed.
- FIFO memory: Conversion stops when all data set in memory is output
- RING memory: Conversion stops when output for the set number of repeat times is completed

If more than one channel are converted, when the stop condition is satisfied, the sampling stops after the conversion of the all channels completes.

If you only perform this function, the connection of the event controller isn't changed. This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.
