7.3.2. SPI Console-Anwendung VB.NET
Das folgende Programmierbeispiel für VB.NET zeigt, wie eine Verbindung mit dem
AnaGate SPI aufgebaut wird und Daten auf den SPI-Bus gesendet bzw. empfangen
werden.
Anmerkung
Der vollständige Quellcode des vorliegenden Beispiels ist auf der jedem
Gerät beiliegenden CD-ROM im Verzeichnispfad Samples/SPI-VB.NET zu
finden.
Sub Main()
Dim hHandle As Int32, nIndex As Integer
Dim BufferWrite(100) As Byte, BufferRead(100) As Byte
Dim nBaudrate As Int32 = 5000000 ' 500kBit
Dim nSigLevel As Byte = 2
Dim nAuxVoltage As Byte = 0 ' support voltage is +3.3V.
Dim nClockMode As Byte = 3
Dim nRC = SPIOpenDevice(hHandle, "192.168.1.254", 5000)
If nRC <> 0 Then
