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.
