1.写源文件

主要完成以下函数实现对硬件资源的控制

XXX_Close (Device Manager)

XXX_Deinit (Device Manager)

XXX_Init (Device Manager)

XXX_IOControl (Device Manager)

XXX_Open (Device Manager)

XXX_PowerDown (Device Manager)

XXX_PowerUp (Device Manager)

XXX_Read (Device Manager)

XXX_Seek (Device Manager)

XXX_Write (Device Manager)

以上函数不必全部实现只跟据需要完成需要的就行了

BOOL WINAPI

DllEntry(HANDLE hinstDLL,

DWORD dwReason,

LPVOID /* lpvReserved */)

{

switch(dwReason)

{

case DLL_PROCESS_ATTACH:

DEBUGREGISTER((HINSTANCE)hinstDLL);

return TRUE;

case DLL_THREAD_ATTACH:

break;

case DLL_THREAD_DETACH:

break;

case DLL_PROCESS_DETACH:

break;

#ifdef UNDER_CE

case DLL_PROCESS_EXITING:

break;

case DLL_SYSTEM_STARTED:

break;

#endif

}

return TRUE;

}

BOOL MY_Deinit(DWORD hDeviceContext)

{

BOOL bRet = TRUE;

RETAILMSG(1,(TEXT("USERMY: MY_Deinit/r/n")));

return TRUE;

BOOL MYGpioInit()

{

RETAILMSG(1,(TEXT("MY_Gpio_Setting----/r/n")));

return TRUE;

}

DWORD MY_Init(DWORD dwContext)

{

RETAILMSG(1,(TEXT("MY_Init----/r/n")));

// 1. Virtual Alloc

Virtual_Alloc();

MYGpioInit();

mInitialized = TRUE;

return TRUE;

}

BOOL MY_IOControl(DWORD hOpenContext,

DWORD dwCode,

PBYTE pBufIn,

DWORD dwLenIn,

PBYTE pBufOut,

DWORD dwLenOut,

PDWORD pdwActualOut)

{

switch(dwCode)

{

Case XXX:

{

  ………………

}

default:

break;

}

RETAILMSG(1,(TEXT("MY:Ioctl code = 0x%x/r/n"), dwCode));

return TRUE;

}

//-----------------------------------------------------------------------------

DWORD MY_Open(DWORD hDeviceContext, DWORD AccessCode, DWORD ShareMode)

{

RETAILMSG(1,(TEXT("USERMY: MY_Open/r/n")));

return true；

}

BOOL MY_Close(DWORD hOpenContext)

{

RETAILMSG(1,(TEXT("USERMY: MY_Close/r/n")));

return TRUE;

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

void MY_PowerDown(DWORD hDeviceContext)

{

RETAILMSG(1,(TEXT("USERMY: MY_PowerDown/r/n")));

//RETAILMSG(1,(TEXT("CAMERA: MY_PowerDown, m_Dx = D%u, init %d /r/n"), m_Dx,

mInitialized));

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

void MY_PowerUp(DWORD hDeviceContext)

{

RETAILMSG(1,(TEXT("USERMY: MY_PowerUp/r/n")));

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

DWORD MY_Read(DWORD hOpenContext, LPVOID pBuffer, DWORD Count)

{

RETAILMSG(1,(TEXT("USERMY: MY_Read/r/n")));

return TRUE;

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

DWORD MY_Seek(DWORD hOpenContext, long Amount, DWORD Type)

{

RETAILMSG(1,(TEXT("USERMY: MY_Seek/r/n")));

return 0;

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

DWORD MY_Write(DWORD hOpenContext, LPCVOID pSourceBytes, DWORD NumberOfBytes)

{

RETAILMSG(1,(TEXT("USERMY: MY_Write/r/n")));

return 0;

}

DWORD MY_Seek(DWORD hOpenContext, long Amount, DWORD Type)

{

RETAILMSG(1,(TEXT("USERMY: MY_Seek/r/n")));

return 0;

}

//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------

DWORD MY_Write(DWORD hOpenContext, LPCVOID pSourceBytes, DWORD NumberOfBytes)

{

RETAILMSG(1,(TEXT("USERMY: MY_Write/r/n")));

return 0;

}

3.makefile文件

#

# DO NOT EDIT THIS FILE!!! Edit ./sources. if you want to add a new source

# file to this component. This file merely indirects to the real make file

# that is shared by all the components of Peg

#

!INCLUDE $(_MAKEENVROOT)/makefile.def

4.def导出文件

;

; Windows CE MY Driver. Written by capbily

LIBRARY userMY

EXPORTS

MY_Close

MY_Deinit

MY_Init

MY_IOControl

MY_Open

5.修改 pb中platfrom.bib文件，加入如下内容

;mydriver

mydriver.dll $(_FLATRELEASEDIR)/mydriver.dll NK SH

6.修改注册表文件，在platform.reg中加入

 [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/MYdriver]

"Prefix"="mydriver"

"Dll"="mydriver.dll"

7.

重新编译内核，点PB5 的主菜单Build OS --> Sysgen 即可，这样就可以生成包含以

上my驱动的内核映象文件NK.bin 和NK.nb0 了。

 

8.evc编写测试应用程序

  要在应用程序中调用驱动程序，Createfile（）打开驱动程序，当调用craetefile时首先调用文件管理器，文件管理器对其进行判断，判断不是文件然后交给设备管理器，设备管理器把驱动程序映射到自己的内存空间。

  HANDLE MYdriver=CreateFile(L"MY1:",GENERIC_READ|GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,NULL );

ReadFile(MYdriver，………………..)

DeviceIoControl(MYdriver,IO_CTL_MY_CLEAR,NULL,0,NULL,0,NULL,NULL);
