ELEKTOR FORUMS

Hi all

In the elektor magazine of NOV 2007 , there is an article of USB DATA ACQUISITION CARD , I read the code but on the PC side .NET FRAMEWORK is used for communicating with the DAQ card.

Is there any way to use that same code of PIC18f4550 to communicate with LABVIEW on the PC side instead of .NET FRAMEWORK?

I want to use labview to communicate with that USB DAQ card, please send me labview file which is compatibe with that code.

Any help greatly appreciated

mek_controlyea there is away to do that but u must first know the function and paramters of dll file so if any one could explain these things it will be easy to interface with labview

Functions and parameters can be found in the C++ code.

These are from the C# code:

    [DllImport("mpusbapi.dll")]
    static extern int _MPUSBGetDeviceCount(string pVID_PID);

    [DllImport("mpusbapi.dll")]
    static extern int _MPUSBOpen(int iInstance, string pVID_PID, string pEP, int dwDir, int dwReserved);

    [DllImport("mpusbapi.dll")]
    static extern int _MPUSBRead(int iHandle, byte[] pData, int dwLen, ref int pLength, int dwMilliseconds);

    [DllImport("mpusbapi.dll")]
    static extern int _MPUSBWrite(int iHandle, byte[] pData, int dwLen, ref int pLength, int dwMilliseconds);

    [DllImport("mpusbapi.dll")]
    static extern int _MPUSBReadInt(int iHandle, byte[] pData, int dwLen, ref int pLength, int dwMilliseconds);

    [DllImport("mpusbapi.dll")]
    static extern Boolean _MPUSBClose(int iHandle);

Please see this thread.

"mek_control"but first dose any body assemble this card correctly
