uint64_t GenGetDataLengthMin

(

TpDeviceHandle_t

hDevice

)

Get the minimum length of the waveform buffer.

Parameters

hDevice

A device handle.

Returns

Minimum waveform buffer length in samples.

Since

0.4.2

uint64_t GenGetDataLengthMax

(

TpDeviceHandle_t

hDevice

)

Get the maximum length of the waveform buffer.

Parameters

hDevice

A device handle.

Returns

Maximum waveform buffer length in samples.

Since

0.4.0

uint64_t GenGetDataLength

(

TpDeviceHandle_t

hDevice

)

Get the length of the currently loaded waveform pattern.

Parameters

hDevice

A device handle.

Returns

Waveform pattern length in samples.

Since

0.4.0

void GenSetData	(	TpDeviceHandle_t	hDevice,
		float *	pBuffer,
		uint64_t	qwSampleCount
	)

Load a waveform pattern into the waveform buffer.

Parameters

hDevice	A device handle.
pBuffer	Pointer to buffer with waveform data.
qwSampleCount	Number of samples in the pattern.

Remarks

Signal type must be set to arbitrary mode to load a waveform pattern into the waveform buffer.

When the generator is active, uploading new a waveform pattern will shortly interrupt the output signal.

Since

0.4.0
