简单的流驱动

具体链接如下：

这个链接我看到学到了一种测试方法！因为学习三星的内容并没有提供详细的方法写应用程序去测试流驱动。

先将方法整个流驱动和测试代码方法写出来：

一、流驱动部分

1.新建一个目录 %/WINCE500/PLATFORM/SMDK2450/Src/Drivers/driver_test（该目录是BSP包驱动程序的存放位置）

2.修改:/WINCE500/PLATFORM/SMDK2450/Src/Drivers/dir文件

DIRS=ceddk     /

     Display_2450  /

   Display_2443  /

     touch     /

     wavedev /

     cs8900eboot /

     iic   /

     camera   /

     PowerButton /

     Usb /

     Keybd  /

     Serial /

     HSMMC  /

     CF_ATAPI  /

     SDBUS /

     SDMEMORY /

     SDHC /

     POST  /

     hspi  /

     NLED /

     driver_test/

3.用文本编辑器建立 4个文本文件，文件名分别为 driver_test.cpp，driver_test.h，

driver_test.def和 source,makefile目录下的文件如图所示

4.编写def文件

library driver_test

EXPORTS

  STR_Init

  STR_Open

  STR_Close

  STR_Deinit

  STR_Powerup

  STR_Powerdown

  STR_IOControl

  STR_Read

  STR_Write

5.编写source文件

SYNCHRONIZE_DRAIN=1

 

RELEASETYPE=PLATFORM

TARGETNAME=driver_test

DEFFILE=driver_test.def

TARGETTYPE=DYNLINK

DLLENTRY=_DllMainCRTStartup

TARGETLIBS= /

   

$(_COMMONSDKROOT)/lib/$(_CPUINDPATH)/coredll.lib /

 

SOURCELIBS=

INCLUDES=$(INCLUDES);$(_TARGETPLATROOT)/src/inc;

SOURCES= /

  driver_test.cpp   /

6.修改注册表

[HKEY_LOCAL_MACHINE/Drivers/BuiltIn/STR]

"Prefix"="STR"

"Dll"="driver_test.dll" 

 "Index"=dword:0;端口为0，写测试程序的时候记得哦，本人因为没注意到所以郁闷了一天下午

"Order"=dword:0

7.修改映象文件

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

8、增加makefile文件内容

!if 0

#

!INCLUDE $(_MAKEENVROOT)/makefile.def

 

9、driver_test.cpp代码

#include <windows.h>
#include <pm.h>
#include <bsp.h>
#include "driver_test.h"
#include <oal.h>
#include <s3c2450.h>
#include <s3c2450_intr.h>
#include <intr.h>
#include <bsp_cfg.h>
#include <ceddk.h>
#include <nkintr.h>
#define sizebf 256
int Tmp,Count;

TCHAR buffer[sizebf];

DWORD STR_Init(DWORD dwContext)
{
 UINT32 sysIntr, irq;
 ULONG value;
 DWORD dwErr;
 Tmp=0;
 Count=0;
 RETAILMSG(1,(TEXT("---――--driver test : STR_Init---------

/r/n")));
 return 1;
}

DWORD STR_Deinit(DWORD dwContext)
{
 RETAILMSG(1,(TEXT("-------driver test : STR_Deinit----------

/r/n")));
 return 1;
}

DWORD STR_Open(DWORD dwData, DWORD dwAccess, DWORD dwShareMode)
{
 RETAILMSG(1,(TEXT("---------driver test : STR_Open-----------

/r/n")));
 Tmp++;
 return Tmp;
}

DWORD STR_Close(DWORD dwContext)
{
 RETAILMSG(1,(TEXT("---------driver test : STR_close-----------

/r/n")));
 if(Count!=0)
  Count--;
 return 1;
}

DWORD STR_Read(DWORD hOpencontext,LPVOID pBuffer,DWORD Count)
{

 RETAILMSG(1,(TEXT("---------driver test : STR_Read-----------

/r/n")));
 uchar *pReadBuffer;
 if((pBuffer==NULL)||(Count<=0))
 {
  RETAILMSG(1,(TEXT("-----driver test : STR_Read error-

----- /r/n")));
  return 0;
 }
 pReadBuffer=(uchar *)MapPtrToProcess(pBuffer,GetCallerProcess

());
 *pReadBuffer=Tmp;
 wcsncpy((LPWSTR)pBuffer,buffer,Count);
 RETAILMSG(1,(TEXT("Lanshuguang---STR_Read:---%s---

/r/n"),pBuffer));
 return 1;
}

DWORD STR_Write(DWORD hOpencontext,LPVOID pBuffer,DWORD Count){
 uchar *pWriteBuffer;
 wcsncpy(buffer,(LPWSTR)pBuffer,Count);
 if((pBuffer==NULL)||(Count<=0)){
  RETAILMSG(1,(TEXT("----driver test : STR_Write error-

----- /r/n")));
  return 0;
 }
 RETAILMSG(1,(TEXT("Lanshuguang---SSTR_Write:---%s---

/r/n"),pBuffer));
 pWriteBuffer=(uchar *)MapPtrToProcess

(pBuffer,GetCallerProcess());
 Tmp=*pWriteBuffer;
 RETAILMSG(1,(TEXT("---driver test : STR_Writeaaa---%x-----

/r/n"),Tmp));
 return 1;
}

BOOL
WINAPI
DllMain(
  HANDLE  hinstDll,
  DWORD   dwReason,
  LPVOID  lpReserved
  )
{
 switch(dwReason)
 {
 case DLL_PROCESS_ATTACH:
  RETAILMSG(1,(TEXT("LanShuGuang-----driver test :

STR_attach----- /r/n /r/n /r/n")));
  break;
 case DLL_PROCESS_DETACH:
  RETAILMSG(1,(TEXT("LanShuGuang-----driver test :

STR_detach------ /r/n")));
  break;
 }
return TRUE;
}

 10、将driver_test文件夹编译，后sysgen，至此一个名为STR的流驱动就写好了

二、测试部分

请参考GOOGLEMAN的测试代码就行了

在dnw可以看到打印信息

---------driver test : STR_Open-----------
Lanshuguang---SSTR_Write:---This is a TEST of TTT Driver---
---driver test : STR_Writeaaa---54-----
---------driver test : STR_Read-----------
Lanshuguang---STR_Read:---This is a TEST of TTT Driver---
---------driver test : STR_close-----------
