Dim DeviceHandle As IntPtr
Dim DelimitedStyle As Integer
Dim DeviceNumber As Integer
Dim BoardType As String
Dim SamplingRate As String
Dim FirmwareVersion As String
Dim ChannelNumber As Byte
Dim value As String
 
value = instance.Fast_Data_Request(DeviceHandle, DelimitedStyle, DeviceNumber, BoardType, SamplingRate, FirmwareVersion, ChannelNumber)

public string Fast_Data_Request( 
   IntPtr DeviceHandle,
   int DelimitedStyle,
   int DeviceNumber,
   string BoardType,
   string SamplingRate,
   string FirmwareVersion,
   byte ChannelNumber
)

Parameters

DeviceHandle: Type: System.IntPtr
The handle associated with the USB device.
DelimitedStyle: Type: System.Int32
The delimited style including the delimiter and terminator characters.
DeviceNumber: Type: System.Int32
The device number associated with the USB device.
BoardType: Type: System.String
The type of board associated with the USB device.
SamplingRate: Type: System.String
The sampling rate associated with the USB device.
FirmwareVersion: Type: System.String
The firmware version associated with the USB device.
ChannelNumber: Type: System.Byte
The channel number associated with the USB device.

Return Value

Type: System.String
A string of samples contained in the buffer; otherwise Error

Remarks

The returned value should be a string of data which will vary in size depending on how many samples are in the buffer.
If there are no ADC Values in the buffer, then the response will be an empty string.

Example

If the is zero, then the return value will have the following format:
Counter [,] Number of Samples [,] ADC Value [,] Place Holder [,] Place Holder [,] Place Holder [,] Date [,] Time
