ActivateDevice This function loads a device driver. HANDLE ActivateDevice( LPCWSTR lpszDevKey, DWORD dwClientInfo ); ActivateDeviceEx This function loads a driver and adds its registry values to the Active key in the registry. HANDLE ActivateDeviceEx( LPCWSTR lpszDevKey, LPCVOID lpRegEnts, DWORD cRegEnts, LPVOID lpvParam ); Loading Device Drivers Developing a Device Driver

Stream Interface is appropriate for any I/O device that produces or consumes streams of data. A good example: Serial port device, bad example: Display device Stream Driver is a DLL and has 12 standard Entry Points(函式/介面) (Init 、Deinit、I OControl、PowerDown、PowerUp、Open、 Read、 Write、 Seek、 Close..etc ) 怎麼判斷是否為Stream Driver ？ ？ public\common\oak\drivers下 的 def 檔，通常會使用 CreateFile("XXXN:", FILES_EXIST, ....) DeviceIoControl 操作的 Driver 都是 Stream Driver，即將 Driver 模擬成檔案來操作 Several ways to implement the stream driver: 1. With only Init and Deinit entry points and no device prefix. ==>You cannot access this driver using CreateFile. (e.g. %_WINCEROOT%\Public\Common\OAK\Drivers\RegEnum) 2.With device prefix in driver entry points. ==> DWORD DEM_ Init( LPCTSTR pContext, LPCVOID lpvBusContext) { OutputDebugString(L"DEM_DRIVER - DEM_Init - Context: "); OutputDebugString(pContext); OutputDebugString(L"\n"); OutputDebugString(L"DEM_DRIVER - Exit DEM_In...

DllMain Callback Function ---Windows架構下呼叫dll的主程式結構 BOOL WINAPI DllMain( __in HINSTANCE hinstDLL , __in DWORD fdwReason , __in LPVOID lpvReserved ); XXX_IOControl (Device Manager) This function sends a command to a device. BOOL XXX_IOControl( DWORD hOpenContext, DWORD dwCode, PBYTE pBufIn, DWORD dwLenIn, PBYTE pBufOut, DWORD dwLenOut, PDWORD pdwActualOut ); Parameters hOpenContext [in] Handle to the open context of the device. The XXX_Open (Device Manager) function creates and returns this identifier. dwCode [in] I/O control operation to perform. These codes are device-specific and are usually exposed to developers through a header file. pBufIn [in] Pointer to the buffer containing data to transfer to the device. dwLenIn [in] Number of bytes of data in the buffer specified for pBufIn. pBufOut [out] Pointer to the buffer used to transfer the output data from the device. dwLenOut [in] Maximum number of bytes in the buffer specified by pBufOut. pdwActualOut [out] Pointer to the DWORD bu...

SOURCES文件是WINCE底层开发中最重要的文件之一,主要的配置项如下: TARGETNAME,定义模块名称. TARGETTYPE,模块的种类,可以是DYNLINK, LIBRARY,EXE. 如果TARGETTYPE是DLL,则可以定义DLLENTRY,将Dll入口定义成别的不是DLLMain的函数,如果DLL的入口是DllMain，则不需要别的定义。 如果TARGETTYPE是EXE,则可以定义EXEENTRY,用于指定EXE的入口函数. 如果TARGETTYPE是LIBRARY,则不需要定义入口函数。 INCLUDES，如果一个模块需要使用非标准路径下的头文件时,需要定义INCLUDES,用于包含更多的头文件路径,用法如下: INCLUDES=$(INCLUDES);\new directory\...,注意定义新的INCLUDES时,需要包含INCLUDES原来的值，否则就需要包含所有可能的目录。 TARGETLIBS,SOURCELIBS用于定义该模块需要链接哪些库文件. TARGETLIBS，如果一个库以DLL的形式提供给调用者，就需要用TARGETLIBS，它只链接一个函数地址，系统执行时会将被链接的库加载。比如coredll.lib就是这样的库文件。即动态链接。 SOURCELIBS，将库中的函数实体链接进来。即静态链接，用到的函数会在我们的文件中形成一份拷贝。 注意，内核这个执行文件是没有TARGETLIBS的，GIISR.DLL也不能有TARGETLIBS。 WINCECOD,如果将其定义为1,则编译器会为每一个文件生成.cod文件,它是一个汇编文件，调试时查看汇编代码也是一种很好的办法。 SOURCES,定义该模块需要哪些源文件. 文章轉載自 WINCE Driver and BSP Develop Blog
