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! |
