Array transfer which performs an initial SPI transmit (MOSI only, no read back) then starts a read stream. This is useful if you need to issue a write to the DUT, then immediately start reading back data, without the USB transfer overhead of approx 150us

Copy

public uint[] WriteReadTransferArray(
	IEnumerable<uint> InitialMOSIData,
	bool InitialDrActive,
	IEnumerable<uint> MOSIReadData,
	uint NumBuffers
)

Public Function WriteReadTransferArray ( 
	InitialMOSIData As IEnumerable(Of UInteger),
	InitialDrActive As Boolean,
	MOSIReadData As IEnumerable(Of UInteger),
	NumBuffers As UInteger
) As UInteger()

public:
array<unsigned int>^ WriteReadTransferArray(
	IEnumerable<unsigned int>^ InitialMOSIData, 
	bool InitialDrActive, 
	IEnumerable<unsigned int>^ MOSIReadData, 
	unsigned int NumBuffers
)

member WriteReadTransferArray : 
        InitialMOSIData : IEnumerable<uint32> * 
        InitialDrActive : bool * 
        MOSIReadData : IEnumerable<uint32> * 
        NumBuffers : uint32 -> uint32[]

Parameters

InitialMOSIData: Type: System.Collections.GenericIEnumerableUInt32
MOSI data to transmit before read (SPI words)
InitialDrActive: Type: SystemBoolean
If the initial transmission is DR active or not
MOSIReadData: Type: System.Collections.GenericIEnumerableUInt32
Data sent over the MOSI line during the transfer
NumBuffers: Type: SystemUInt32
Number of buffers (samples) to read

Return Value

Type: UInt32
MISO data from the DUT during the whole transfer
