WriteAperiodicStreamOut [LJM User's Guide]
Requires LJM 1.2100 or later.
Writes data to a buffer for the aperiodic stream-out at the specified index.This function can be called before starting stream (after calling LJM_InitializeAperiodicStreamOut) to preemptively queue up data for the device stream out buffer.
Syntax
LJM_ERROR_RETURN LJM_WriteAperiodicStreamOut( int Handle, int StreamOutIndex, int NumValues, const double * aWriteData int * LJMBufferStatus)
Parameters
Handle[in]
A device handle. The handle is a connection ID for an active device. Generate a handle with LJM_Open or LJM_OpenS.
StreamOutIndex[in]
The number assigned to this stream-out. See the Stream Out section of the T-series datasheet for more information.
NumValues[in]
The number of values to write to the stream-out buffer.
aWriteData[in]
The data array to be written to the stream-out buffer.
LJMBufferStatus[out]
the number of samples that can be written to the stream-out queue.
Returns
LJM errorcodes or 0 for no error.
Remarks
See LJM_InitializeAperiodicStreamOut for usage.
Configuration
This function writes to the following registers. When using LJM_WriteAperiodicStreamOut for a given stream index, they should not be set manually:
STREAM_OUT#(0:3)_BUFFER_U16STREAM_OUT#(0:3)_SET_LOOP
Example
See LJM_InitializeAperiodicStreamOut for an example.
