OME-PIO-DA Software Manual [Win 95/98/NT/2000]

1. Introduction

The software is a collection of digital I/O subroutines for the OME-PIO­DIO series add-on cards for Windows 95/98/NT/2000 applications. These
subroutines are written with C language and perform a variety of digital I/O
operations.

The subroutines in PIODA.DLL are user friendly. It provides powerful,
easy-to-use subroutine for developing your data acquisition application. Your
program can call these DLL functions by VC++, VB, Delphi, and BORLAND
C++ Builder easily. To speed-up your developing process, some
demonstration source program are provided.

Please refer to the following user manuals:

• PnPInstall.pdf:

To install the PnP (Plug and Play) driver for PCI card under Windows

95/98.

• SoftInst.pdf:

To install the software package under Windows 95/98/NT/2000.

• CallDll.pdf:

To call the DLL functions with VC++5, VB5, Delphi3 and Borland C++

Builder 3.

• ResCheck.pdf:

To check the resources I/O Port address, IRQ number and DMA

number for add-on cards under Windows 95/98/NT/2000.

• OME-PIO-DAHW.pdf:

OME-PIO-DA16/DA8/DA4 Hardware manual.

4.6.5 Architecture of Interrupt mode

Please refer to the following Windows API functions:

The following description of these functions was extracted from MSDN.

For the detailed and completely information, please refer to MSDN.

CreateEvent( )

The CreateEvent function creates or opens a named or unnamed

event object.

HANDLE CreateEvent(
// pointer to security attributes

LPSECURITY_ATTRIBUTES lpEventAttributes,
BOOL bManualReset, // flag for manual-reset event
BOOL bInitialState, // flag for initial state
LPCTSTR lpName // pointer to event-object name

);

Date Mar-15-2000 Ver 2.10.00 Page 47

OME-PIO-DA Software Manual [Win 95/98/NT/2000]

CreateThread( )

The CreateThread function creates a thread to execute within the

virtual address space of the calling process.

To create a thread that runs in the virtual address space of another

process, use the CreateRemoteThread function.

HANDLE CreateThread(

// pointer to security attributes
LPSECURITY_ATTRIBUTES lpThreadAttributes,
DWORD dwStackSize, // initial thread stack size
// pointer to thread function
LPTHREAD_START_ROUTINE lpStartAddress,
LPVOID lpParameter, // argument for new thread
DWORD dwCreationFlags, // creation flags
LPDWORD lpThreadId // pointer to receive thread ID

);

WaitForSingleObject( )

The WaitForSingleObject function returns when one of the following

occurs:

• The specified object is in the signaled state.

• The time-out interval elapses.

To enter an alertable wait state, use the WaitForSingleObjectEx

function. To wait for multiple objects, use the WaitForMultipleObjects.

DWORD WaitForSingleObject(

HANDLE hHandle, // handle to object to wait for
DWORD dwMilliseconds // time-out interval in

milliseconds

);
