Add support for the R & D data collection module in the QT Project

1. Correctly install the analyticdb module ManagementProgramAdvantech Device ManagerAnd install the driver.

  

2. ChangeC: \ Program Files \ advantech \ adsapiPATH (default installation location)Include,LibCopy folderQtUnder the project folder.

  

3.CodeAdd the header file of the function library of the wasu data collection module:

# Include "include \ driver. H"

Add the system header file:

# Include <windef. h>

# Include <stdio. h>

 

4.ProAdd the function library file of the wasu data collection module to the file.

Headers + = include/driver. h

Libs + = lib/adsapi32.lib

 

5. Basic code:

1, Open the driver

DWORD dwerrcde = drv_deviceopen (0, & ldriverhandle );

If (dwerrcde! = Success ){

Qdebug () <"dwerrcde =" <dwerrcde;

Exit (1 );

}

2, ReadIoInput number

Pt_dioreadportword m_ptdioreadportword;

Ushort m_validmask = 0;

Ushort m_divalue = 0;

M_ptdioreadportword.port = 0;

M_ptdioreadportword.validchannelmask = (ushort far *) & m_validmask;

M_ptdioreadportword.value = (ushort far *) & m_divalue;

Lresult m_errcde = drv_dioreadportword (ldriverhandle, (lpt_dioreadportword) & m_ptdioreadportword );

If (m_errcde! = Success ){

Qdebug () <"m_errcde =" <m_errcde;

Exit (1 );

}

 

3, OutputIoNumber

Pt_diowritebit ptdiowritebit;

Ptdiowritebit. Port = 0; // output port: 0

Ptdiowritebit. Bit = 0; // output channel: 0

Ptdiowritebit. State =! (Tmp_bit & current_dataout); // output state

///*

DWORD dwerrcde = drv_diowritebit (ldriverhandle, (lpt_diowritebit) & ptdiowritebit );

If (dwerrcde! = Success ){

Qdebug () <"dwerrcde =" <dwerrcde;

Exit (1 );

}//*/

4Disable the driver

DWORD dwerrcde = drv_deviceclose (& ldriverhandle );

If (dwerrcde! = Success ){

Qdebug () <"dwerrcde =" <dwerrcde;

Exit (1 );

}
