Sets the source waveform settings required for parallel sourcing. Settings apply across all sites if multiple sites are configured in the pin map. You cannot reconfigure settings after waveforms are created.

C Function Prototype: ViStatus niDigital_CreateSourceWaveformParallel (ViSession vi, ViConstString pinList, ViconstString waveformName, ViInt32 dataMapping)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
pinList	Source pins for the waveform. The pinList must match the source pins in the pattern that references the waveform. The pin order in the pinList determines the bit positions of the data written by the niDigital_WriteSourceWaveform function.
waveformName	The name to assign to the waveform. Use the waveformName with source_start opcode in your pattern.
dataMapping	Parameter that specifies how to map data on multiple sites. - NIDIGITAL_VAL_BROADCAST (2600): Broadcasts the waveform you specify to all sites. - NIDIGITAL_VAL_SITE_UNIQUE (2601): Sources unique waveform data to each site.

Return value: Reports the status of the operation.

Sets the source waveform settings required for serial sourcing. Settings apply across all sites if multiple sites are configured in the pin map. You cannot reconfigure settings after waveforms are created.

C Function Prototype: ViStatus niDigital_CreateSourceWaveformSerial (ViSession vi, ViConstString pinList, ViConstString waveformName, ViInt32 dataMapping, ViUInt32 sampleWidth, ViInt32 bitOrder)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
pinList	Source pins for the waveform. The pinList must match the source pins in the pattern that references the waveform. The pin order in the pinList determines the bit positions of the data written by the niDigital_WriteSourceWaveform function.
waveformName	The name to assign to the waveform. Use the waveformName with source_start opcode in your pattern.
dataMapping	Parameter that specifies how to map data on multiple sites. - NIDIGITAL_VAL_BROADCAST (2600): Broadcasts the waveform you specify to all sites. - NIDIGITAL_VAL_SITE_UNIQUE (2601): Sources unique waveform data to each site.
sampleWidth	Width in bits of each serial sample. Valid values are between 1 and 32.
bitOrder	Order in which to shift the bits. - NIDIGITAL_VAL_MSB_FIRST (2500): Specifies the bit order by most significant bit first. - NIDIGITAL_VAL_LSB_FIRST (2501): Specifies the bit order by least significant bit first.

Return value: Reports the status of the operation.

Creates a source waveform with configuration information from a TDMS file generated by the Digital Pattern Editor. It also optionally writes waveform data from the file.

C Function Prototype: ViStatus niDigital_CreateSourceWaveformFromFileTDMS (ViSession vi, ViConstString waveformName, ViConstString waveformFilePath, ViBoolean writeWaveformData)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
waveformName	The waveform name you want to use from the file. You must specify waveformName if the file contains multiple waveforms. Use the waveformName with the source_start opcode in your pattern.
waveformFilePath	Absolute file path to the load source waveform file (.tdms).
writeWaveformData	A Boolean that writes waveform data to source memory if True and the waveform data is in the file.

Return value: Reports the status of the operation.

Writes the same waveform data to all sites. Use this write function if you set the dataMapping parameter of the create source waveform function to Broadcast.

C Function Prototype: ViStatus niDigital_WriteSourceWaveformBroadcastU32 (ViSession vi, ViConstString waveformName, ViInt32 waveformSize, ViUInt32[] waveformData)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
waveformName	The name to assign to the waveform. Use the waveformName with source_start opcode in your pattern.
waveformSize	Size of the data array.
waveformData	1D array of samples to use as source data to apply to all sites.

Return value: Reports the status of the operation.

Writes one waveform per site. Use this write function if you set the parameter of the create source waveform function to Site Unique.

C Function Prototype: ViStatus niDigital_WriteSourceWaveformSiteUniqueU32 (ViSession vi, ViConstString siteList, ViConstString waveformName, ViInt32 numWaveforms, ViInt32 samplesPerWaveform, ViUInt32[] waveformData)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
siteList	Site numbers listed as a comma-delimited list of strings of form siteN, where N is the site number.
waveformName	The name to assign to the waveform. Use the waveformName with source_start opcode in your pattern.
numWaveforms	Number of waveforms.
samplesPerWaveform	Number of samples per waveform.
waveformData	An array of samples to use as source data. Data for each site must be appended sequentially in the array (non-interleaved).

Return value: Reports the status of the operation.

Writes a source waveform based on the waveform data and configuration information the file contains.

C Function Prototype: ViStatus niDigital_WriteSourceWaveformDataFromFileTDMS (ViSession vi, ViConstString waveformName, ViConstString waveformFilePath)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
waveformName	The name to assign to the waveform. Use the waveformName with source_start opcode in your pattern.
waveformFilePath	Absolute file path to the load source waveform file (.tdms).

Return value: Reports the status of the operation.
