CntSetSamplingClockTrigger

Function

Sets sampling clock trigger conditions.

Format

Ret = CntSetSamplingClockTrigger ( Id , ClockTrg )

Parameters

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

ClockTrg [C: short] [Python: ctypes.c_short]
Specify the sampling clock conditions.

Definition	Value	Description
CNTS_CLOCK_CLOCK	1	Internal Clock
CNTS_CLOCK_EXT_TRG	2	External Clock

Return Value

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

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normal Complete
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID is specified.
CNT_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
CNT_ERR_SYS_MEMORY	20000	It failed in memory allocation for the object preparation.
CNT_ERR_SYS_USING_OTHER_PROCESS	20003	Cannot use because another process is using the device.
CNT_ERR_SYS_CLOCK_TRG	21007	The clock condition is out of range.

Initial Value

Internal Clock

Remarks

Must set clock condition in order to make the application operation regular. This function should be executed in the setting stage before sampling starts. Set the internal clock value by the function CntSetSamplingInternalClock if Internal Clock is used.

Example

C	Ret = CntSetSamplingClockTrigger (Id, CNTS_CLOCK_CLOCK);
Python	Ret = ccnt.CntSetSamplingClockTrigger (Id, ccnt.CNTS_CLOCK_CLOCK)
