驱动开发起步

驱动开发起步

看了近半个月的书，有了一小点的进步。主要是熟悉了一下驱动开发的环境和配置，USB的协议传输等等。下面是这段时间的体会。以开发一个简单的"hello world"为例。 1、先装VC，然后装DDK，我装的是2000DDK，这个顺序不要弄反。 2、配置好环境（1）在setting->link->libary modules添加ntoskrnl.lib hal.lib usbd.lib wdm.lib 。可能不需要这么多。（2）在setting->C/C++->category选preprocessor->additional include directories中添加c:/NTDDK/inc,c:/NTDDK/inc/ddk（３）在option中添加合适的lib,include路径.option->directories选include files添加C:/NTDDK/INC和C:/NTDDK/INC/DDK，在选library files中添加C:/NTDDK/libchk/i386和C:/NTDDK/libfre/i386。整个环境基本上就搭建好了。 3、然后添加代码。 //1.c #ifdef _cplusplus extern "C" { #endif #include "1.h" #ifdef _cplusplus } #endif NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject,       IN PUNICODE_STRING RegistryPath) {  DriverObject->DriverExtension->AddDevice = WDMAddDevice;  DriverObject->MajorFunction[IRP_MJ_PNP] = WDMPnp;  return STATUS_SUCCESS;   } NTSTATUS WDMAddDevice(IN PDRIVER_OBJECT DriverObject,        IN PDEVICE_OBJECT PhysicalDeviceObject) {  NTSTATUS status;  PDEVICE_OBJECT fdo;  PDEVICE_EXTENSION dx;  status = IoCreateDevice(   DriverObject,   sizeof(DEVICE_EXTENSION),   NULL,   FILE_DEVICE_UNKNOWN,   0,   FALSE,   &fdo);  if(!NT_SUCCESS(status))   return status;  dx = (PDEVICE_EXTENSION)fdo->DeviceExtension;  dx->fdo=fdo;  dx->NextStackDevice = IoAttachDeviceToDeviceStack(fdo,PhysicalDeviceObject);  fdo->Flags |= DO_BUFFERED_IO|DO_POWER_PAGABLE;  fdo->Flags &= ~DO_DEVICE_INITIALIZING;  return STATUS_SUCCESS; } NTSTATUS WDMPnp( IN PDEVICE_OBJECT fdo,     IN PIRP Irp) {  PDEVICE_EXTENSION dx = (PDEVICE_EXTENSION)fdo->DeviceExtension;  PIO_STACK_LOCATION IrpStack = IoGetCurrentIrpStackLocation(Irp);  NTSTATUS status;  ULONG MinorFunction = IrpStack->MinorFunction;  IoSkipCurrentIrpStackLocation(Irp);  status = IoCallDriver(dx->NextStackDevice,Irp);  if( MinorFunction==IRP_MN_REMOVE_DEVICE)  {   IoSetDeviceInterfaceState(&dx->ifSymLinkName,FALSE);   RtlFreeUnicodeString(&dx->ifSymLinkName);   if(dx->NextStackDevice)    IoDetachDevice(dx->NextStackDevice);   IoDeleteDevice(fdo);  }  return status; } 1.h #ifdef _cplusplus extern "C" { #endif #include "ntddk.h" #ifdef _cplusplus } #endif typedef struct _DEVICE_EXTENSION {     PDEVICE_OBJECT    fdo;     PDEVICE_OBJECT    NextStackDevice;     UNICODE_STRING    ifSymLinkName; } DEVICE_EXTENSION, *PDEVICE_EXTENSION; NTSTATUS WDMAddDevice(IN PDRIVER_OBJECT DriverObject,        IN PDEVICE_OBJECT PhysicalDeviceObject); NTSTATUS WDMPnp( IN PDEVICE_OBJECT fdo,     IN PIRP Irp); 4、在文件中添加makefile和source,makefile从其它驱动程序中就可以原封不动的考过来，source需要改一点，我的source是： TARGETNAME=1 TARGETTYPE=DRIVER DRIVERTYPE=WDM TARGETPATH=OBJ INCLUDES=$(BASEDIR)/inc;/          $(BASEDIR)/inc/ddk;/ TARGETLIBS=$(DDKROOT)/libfre/i386/ntoskrnl.lib/            $(DDKROOT)/libfre/i386/hal.lib/            $(DDKROOT)/libfre/i386/wdm.lib           SOURCES=1.c/ makefile为（不用改地）： # # 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 driver components of the Windows NT DDK # !INCLUDE $(NTMAKEENV)/makefile.def 5、编译，用DDK中的checked(free) build environment来编译。进入控制台后执行build -cz，其中如果编译不通可以用nmake来调试。 6、build完成后，就会生成一个1.sys文件。 7、给设备写inf文件，即安装驱动，inf文件可以从其它驱动文件中拷贝过来，做点小改动就可以了。下面是我写的， [Version] Signature="$Chicago$" Class=Unknown Provider=%THU% [Manufacturer] %THU% = WdmDriver [WdmDriver] %WdmDriver%=WdmDriver.Install, *WdmDriver [DestinationDirs] WdmDriver.Files.Driver=10, System32/Drivers WdmDriver.Files.Driver.NT=10, System32/Drivers [SourceDisksNames] 1="WdmDriver directory",,,obj/i386/ [SourceDisksFiles] 1.sys=1 ;; The Win2K DDK documentation contains an excellent INF reference. ;--------- Version Section --------------------------------------------------- [Version] Signature="$CHICAGO$" Provider=LC_Device DriverVer=8/21/2002,3.0.0.3 ; If device fits one of the standard classes, use the name and GUID here, ; otherwise create your own device class and GUID as this example shows.

MfgName="LC Soft" DeviceDesc="Hello World WDM!" DeviceClassName="LC_Device" SvcDesc="???" 对inf文件的一点小注释，：），inf文件是按照部分来划分的，每个部分用[]来标记。分号；表示注释，%表示（%文本%）表示一个字符串。 一个最基本的起步，未来还有很多工作要做，继续努力！
