EXAMPLE CLASS LIBRARY CODE
Below is our example Class Library source code that performs 3 different protocol decodes and displays the results on the waveline. A version that includes an actual NEC IR decoder is installed with the USBee Suite. Use this example to start your own.
Imports System.IO
Public Class CustomUSBeeSuiteDecoder
Declare Function SampleData Lib "usbeeste.dll" Alias _
"?LoggedData@@YGJK@Z" (ByVal Index As Integer) As UInteger
' The SampleData routine returns a 4 byte value that contains a single
' sample of all the signals
' The format of the 32 bits is as follows:
'
' MSB LSB
' XXXXXXXXYYYYYYYYFEDCBA9876543210
'
' where XXXXXXXX is Channel 2 Analog value (0=-10V, 255 = +10V)
' YYYYYYYY is Channel 1 Analog value (0=-10V, 255 = +10V)
' F is logic level (0 or 1) for channel F
' E is logic level (0 or 1) for channel E
' D is logic level (0 or 1) for channel D
' ...
' 0 is logic level (0 or 1) for channel 0

' This is a custom bus decoder Processing Routine

' The passed in variables are as follows:
' OutFile - the file that all of the decoded Entries get
' written to. This is the file that the Suite
' will read to display the data on the waveline.
' RateIndex - Index of the sample rate samples were taken.
' 17=1Msps,27=2Msps,37=3Msps,47=4Msps
' 67=6Msps,87=8Msps,127=12Msps,167=16Msps
' 247=24Msps
' Parameters - User defined string passed from the Suite user
' interface Channel Setting for this waveline.
' Use this string to pass in any parameters that
' your decoder needs to know, such as what
' channels to use in decoding, which protocol if
' you have multiple protocols supported here,
' and how you want the data formatted.
' Below is an example set of Custom Protocol decoders that show
' how to access the sample buffer and how to generate output that
' get sent to the screen.

Ну собственно нет проблем - есть пункт в меню каналов - "custom protocol parameters" и строка в которую надо чАво ето вводить! Так вот и вопрос чаво и как вводить? У мну ничего не получается! Кто пробовал?
