DAQmxCfgBurstHandshakingTimingImportClock

int32 DAQmxCfgBurstHandshakingTimingImportClock (TaskHandle taskHandle, int32 sampleMode, uInt64 sampsPerChan, float64 sampleClkRate, const char sampleClkSrc[], int32 sampleClkActiveEdge, int32 pauseWhen, int32 readyEventActiveLevel);

Purpose

Configures when the DAQ device transfers data to a peripheral device, using an imported sample clock to control burst handshaking timing.

Parameters

Input
Name	Type	Description
taskHandle	TaskHandle	The task used in this function.
sampleMode	int32	Specifies whether the task acquires or generates samples continuously or if it acquires or generates a finite number of samples. Value Description DAQmx_Val_FiniteSamps Acquire or generate a finite number of samples. DAQmx_Val_ContSamps Acquire or generate samples until you stop the task. DAQmx_Val_HWTimedSinglePoint Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types.
sampsPerChan	uInt64	The number of samples to acquire from each channel if sampleMode is DAQmx_Val_FiniteSamps. If sampleMode is DAQmx_Val_ContSamps, NI-DAQmx uses this value to determine the buffer size.
sampleClkRate	float64	Specifies the sampling rate in samples per channel per second. If you use an external source for the Sample Clock, set this input to the maximum expected rate of that clock.
sampleClkSrc	const char []	Specifies the terminal of the signal to use as the Sample Clock.
sampleClkActiveEdge	int32	Specifies on which edge of a clock pulse sampling takes place. This property is useful primarily when the signal you use as the Sample Clock is not a periodic clock. Value Description DAQmx_Val_Rising Acquire or generate samples on the rising edges of the Sample Clock. DAQmx_Val_Falling Acquire or generate samples on the falling edges of the Sample Clock.
pauseWhen	int32	Specifies whether the task pauses while the signal is high or low.
readyEventActiveLevel	int32	Specifies the polarity for the Ready for Transfer event.

Return Value

Name	Type	Description
status	int32	The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
