开发板WDM驱动程序说明及开发流程

PCI开发板WINDOWS驱动程序说明及开发流程PCI开发板的WINDOWS驱动程序采用DRIVERWORKS提供的WDM驱动程序框架构造支持IO内存和DMA及中断操作采用稳定的DRIVERWORKS2.5版本完全支持PCI结构用户可以在网上下载我们也可以提供以下是DRIVERWORKS的驱动产生向导流程说明在插入PCI开发板前请首先安装DRIVERWORKS2.5和NTDDK安装完成后再正确安装PCI开发板开机进入WINDOWS98界面后系统会自动找到PCI开发板如图选择下一步指定驱动程序的路径后显示系统找到后显示单击下一步系统完成驱动程序安装驱动程序安装完成后在我电脑里的系统属性里会出现表示开发板使用的中断和IO范围及内存范围以下为DRIVERWORKS的驱动程序构造向导流程说明单击DRIVER WIZARD图标显示选择产生一个新的驱动程序输入工程名字和目录,显示点击下一步显示选择WDM驱动程序模式,用户也可以选择NT4.0的驱动模式选择下一步,显示:选择PCI设备,VENDOR ID 1100,DEVICE ID 4252,选择下一步选择下一步:选择驱动属性,选择下一步:选择是否队列化IO请求,用户根据自己需要确定选择是否REGISTRY选择添加一个IO端口,添加中断,如果使用了DMA数据传送,选择添加DMA代码选择设备类的操作函数,用户根据自己需要添加选择是否生成一个应用程序和选项点击FINISH,完成驱动生成向导以下介绍开发板自带测试驱动程序的使用说明执行EXE里的程序后显示程序首先检测是否存在PCI开发板其次检测开发板上的SRAM是否读写正常检查SRAM也是执行IO操作的例子DMA模式选择输入0选择DMA读测试输入1选择DMA 写测试操作选择后开始DMA及中断测试以下是驱动程序的源代码注释及说明用户双击PCIWDM.DSW”文件进入VC6.0编辑状态中如图工程包含两个项目,一个是驱动程序,一个是测试程序PCIWDM是驱动程序,TEST_PCIWDM是测试应用程序注意编译使用前需要设置DRIVERWORKS和NTDDK,选择菜单里面的WRIVERSTUDIO中的DRIVER BUILDING SETTING设置NTDDK路径和CPU类型,类型选择I386,如图编译选择批构件,不要编译IA64的项目,如图编译后生成SYS文件和EXE文件以下是源代码分析:NTSTATUS NewfpgaDevice::NEWFPGA_IOCTL_800_Handler(KIrp I) {NTSTATUS status = STATUS_SUCCESS;//LED灯显示程序long j;m_IoPortRange0.outd(0x48,0x1);//灯1亮//DELAY 1秒for (j=0;j<2000000;j++) {m_IoPortRange0.outd(0xf0,0x0);}m_IoPortRange0.outd(0x48,0x2);//灯2亮//DELAY 1秒for (j=0;j<2000000;j++) {m_IoPortRange0.outd(0xf0,0x0);}m_IoPortRange0.outd(0x48,0x3);//灯1,2亮//DELAY 1秒for (j=0;j<2000000;j++) {m_IoPortRange0.outd(0xf0,0x0);}m_IoPortRange0.outd(0x48,0x0);//灯1,2熄rmation() = 0;status;return}NTSTATUS NewfpgaDevice::NEWFPGA_IOCTL_801_Handler(KIrp I) { //7段数码管显示程序NTSTATUS status = STATUS_SUCCESS;int i=0;j=0;longdo {//7段数码管从0至F显示if (i==0) m_IoPortRange0.outd(0x40,0x808);if (i==1) m_IoPortRange0.outd(0x40,0x3e3e);if (i==2) m_IoPortRange0.outd(0x40,0x4444);if (i==3) m_IoPortRange0.outd(0x40,0x1414);if (i==4) m_IoPortRange0.outd(0x40,0x3232);if (i==5) m_IoPortRange0.outd(0x40,0x1111);if (i==6) m_IoPortRange0.outd(0x40,0x101);if (i==7) m_IoPortRange0.outd(0x40,0x3c3c);if (i==8) m_IoPortRange0.outd(0x40,0x0);if (i==9) m_IoPortRange0.outd(0x40,0x1010);if (i==0xa) m_IoPortRange0.outd(0x40,0x2020);if (i==0xb) m_IoPortRange0.outd(0x40,0x303);if (i==0xc) m_IoPortRange0.outd(0x40,0x4949);if (i==0xd) m_IoPortRange0.outd(0x40,0x606);if (i==0xe) m_IoPortRange0.outd(0x40,0x4141);if (i==0xf) m_IoPortRange0.outd(0x40,0x6161);i++;for (j=0;j<2000000;j++) {m_IoPortRange0.outd(0xf0,0x0);}}(i<16);whilem_IoPortRange0.outd(0x40,0xffff);rmation() = 0;returnstatus;}NTSTATUS NewfpgaDevice::NEWFPGA_IOCTL_802_Handler(KIrp I){NTSTATUS status = STATUS_SUCCESS;//按键输入测试程序PTEST_MESSAGE pInput = static_cast<PTEST_MESSAGE>(I.IoctlBuffer());
