SampleDIO.exe


Update
We recommend using the graphical C# version of this app, which is posted at topic 2164. The C# app is easier to use and includes features not found in this app.

This sample command line application demonstrates basic use of the Digital I/O (DIO) driver. It can also be used to interactively control the DIO lines for test purposes.

The application presents the user with a console menu of DIO operations (read, write, get and set direction and mask) to execute, as well as a simple bit walking test.

Key APIs Used


CreateFile
ReadFile
WriteFile
DeviceIoControl

Lines of Code: ~350

Rev 2 Update

We've updated the sample to include interrupts. The sample will attached to the first available and supported interrupt for the device and outputs text to the console on either rising or falling edge interrupts.

You can make this code a little bit more friendly by updating the header file to prevent name mangling and add a couple method definitions:


#ifndef _DIO_H
#define _DIO_H


#ifdef __cplusplus
extern "C"
{
#endif

BOOL GetMask(HANDLE hDioPort, DWORD *pdwMask);
BOOL SetMask(HANDLE hDioPort, DWORD dwMask);
BOOL ReadDio(HANDLE hDioPort, DWORD *pdwDio);
BOOL WriteDio(HANDLE hDioPort, DWORD dwDio);
BOOL SetDirection(HANDLE hDioPort, DWORD dwDir);
BOOL GetDirection(HANDLE hDioPort, DWORD *pdwDir);
DWORD GetUserDword(const char *szStr);
HANDLE OpenDIO();
BOOL CloseDIO(HANDLE hDioPort);

#ifdef __cplusplus
}
#endif
#endif // _DIO_H


And then add these to the implementation file:

HANDLE OpenDIO()
{
	return CreateFile(_T("DIO1:"), GENERIC_WRITE | GENERIC_READ, 
		FILE_SHARE_READ | FILE_SHARE_WRITE, 
		NULL, OPEN_EXISTING, 0, NULL);
}

BOOL CloseDIO(HANDLE hDioPort)
{
	return CloseHandle(hDioPort);
}
