C++MFC界面讀寫USBHID設備數(shù)據(jù)程序

1、第一步：列舉所有的HID裝備：m_ctllHIDdevices.ResetContent();/這是MFC里面一個list控件，用來顯示所有的HID裝備的，假如你沒有界面，可以不須要此行UpdateData(FALSE);/更新界面CStringtemp;intCount=0;/TotalnumberofdevicesfoundDWORDstrSize=0,requiredSize=0;BOOLresult1,result2;ULONGDeviceInterfaceDetailDataSize;/界說一些變量，今后會用到SP_DEVINFO_DATADeviceInfoData;SP_DEVI

2、CE_INTERFACE_DATADeviceInterfaceData;PSP_DEVICE_INTERFACE_DETAIL_DATADeviceInterfaceDetailData;/PSP_DEVICE_INTERFACE_DETAIL_DATAest;第一步：獲取deviceIDGUIDdeviceId;HidD_GetHidGuid(&deviceId);/第二步：獲取裝備信息HDEVINFOhandle;handle=SetupDiGetClassDevs(&deviceId,NULL,NULL,DIGCF_DEVICEINTERFACE|DIGCF_PRESE

3、NT);/GetonlyHIDdevices/第三步：對所有的裝備進行列舉SetupDiEnumDeviceInterfaces();result1=false;/界說一些變量result2=false;CStringtemp11=""doDeviceInterfaceData.cbSize=sizeof(SP_DEVICE_INTERFACE_DATA);result1=SetupDiEnumDeviceInterfaces(handle,NULL,/INPSP_DEVINFO_DATADeviceInfoData,OPTIONAL&deviceId,Count,

4、&DeviceInterfaceData);/獲得裝備具體數(shù)據(jù)(初步)SetupDiGetDeviceInterfaceDetail(handle,&DeviceInterfaceData,NULL,0,&strSize,NULL);requiredSize=strSize;DeviceInterfaceDetailData=(PSP_DEVICE_INTERFACE_DETAIL_DATA)malloc(requiredSize);DeviceInterfaceDetailData->cbSize=sizeof(SP_DEVICE_INTERFACE_DETAI

5、L_DATA);DeviceInfoData.cbSize=s第一步：列舉所有的HID裝備：m_ctllHIDdevices.ResetContent();/這是MFC里面一個list控件，用來顯示所有的HID裝備的,假如你沒有界面,可以不須要此行UpdateData(FALSE);/更新界面CStringtemp;intCount=0;/TotalnumberofdevicesfoundDWORDstrSize=0,requiredSize=0;BOOLresult1,result2;ULONGDeviceInterfaceDetailDataSize;/界說一些變量,今后會用到SP_DEV

6、INFO_DATADeviceInfoData;SP_DEVICE_INTERFACE_DATADeviceInterfaceData;PSP_DEVICE_INTERFACE_DETAIL_DATADeviceInterfaceDetailData;/PSP_DEVICE_INTERFACE_DETAIL_DATAtest;/第一步：獲取deviceIDGUIDdeviceId;HidD_GetHidGuid(&deviceId);/第二步：獲取裝備信息HDEVINFOhandle;handle=SetupDiGetClassDevs(&deviceId,NULL,NULL,

7、DIGCF_DEVICEINTERFACE|DIGCF_PRESENT);/GetonlyHIDdevices/第三步：對所有的裝備進行列舉/SetupDiEnumDeviceInterfaces();result1=false;/界說一些變量result2=false;CStringtemp11=""doDeviceInterfaceData.cbSize=sizeof(SP_DEVICE_INTERFACE_DATA);result1=SetupDiEnumDeviceInterfaces(handle,NULL,/INPSP_DEVINFO_DATADeviceInf

8、oData,OPTIONAL&deviceId,Count,&DeviceInterfaceData);/獲得裝備具體數(shù)據(jù)(初步)SetupDiGetDeviceInterfaceDetail(handle,&DeviceInterfaceData,NULL,0,&strSize,NULL);requiredSize=strSize;DeviceInterfaceDetailData=(PSP_DEVICE_INTERFACE_DETAIL_DATA)malloc(requiredSize);DeviceInterfaceDetailData->cbSiz

9、e=sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA);DeviceInfoData.cbSize=sizeof(SP_DEVINFO_DATA)/再次獲得具體數(shù)據(jù)result2=SetupDiGetDeviceInterfaceDetail(handle,&DeviceInterfaceData,DeviceInterfaceDetailData,strSize,&requiredSize,&DeviceInfoData);/獲得裝備路徑(最主要的部分)temp=DeviceInterfaceDetailData->DevicePat

10、h;UpdateData(FALSE);m_ctllHIDdevices.AddString(temp);Count+;while(result1);UpdateData(false);izeof(SP_DEVINFO_DATA/再次獲得具體數(shù)據(jù)result2=SetupDiGetDeviceInterfaceDetail(handle,&DeviceInterfaceData,DeviceInterfaceDetailData,strSize,&requiredSize,&DeviceInfoData);/獲得裝備路徑(最主要的部分)temp=DeviceInterf

11、aceDetailData->DevicePath;UpdateData(FALSE);m_ctllHIDdevices.AddString(temp);Count+;while(result1);UpdateData(false);第二步：輪回讀取HID裝備數(shù)據(jù)(依據(jù)用戶供給的HID的vendorlD和productID),并且把字節(jié)解碼成二進制，在MFCF面上用LED展現(xiàn)：為了不影響主線程的運行，我把讀取數(shù)據(jù)的操縱，放在一個子線程里！每隔50ms去讀取一次數(shù)據(jù)！起首創(chuàng)建一個線程：HANDLEhThread1;bStopHID=false;/這個變量，今后用來停滯線程UpdateDat

12、a(true);/更新界面，獲取變量UpdateData(false);hThread1=CreateThread(NULL,0,Thread_Enable_Read,(LPVOID)this,NULL,NULL);在線程的程序里：CusbhidDlg*p=(CusbhidDlg*)pvParam;獲取主窗口的指針，用來挪用主窗口的變量和函數(shù)p->UpdateData(true);p->bStopHID=false;CStringtemp;CStringDevicePath;temp=""intCount=0;/Totalnumberofdevicesfound

13、DWORDstrSize=0,requiredSize=0;BOOLresult1,result2;ULONGDeviceInterfaceDetailDataSize;SP_DEVINFO_DATADeviceInfoData;SP_DEVICE_INTERFACE_DATADeviceInterfaceData;PSP_DEVICE_INTERFACE_DETAIL_DATADeviceInterfaceDetailData;PSP_DEVICE_INTERFACE_DETAIL_DATAtest;/1GUIDdeviceId;HidD_GetHidGuid(&deviceId);

14、intvenderID=p->v_eVendorID;/從窗口里獲取用戶輸入的VendorlDintproductID=p->v_eProductID;/從窗口里獲取用戶輸入的ProductIDunsignedcharinbuffer2;/用來存放讀取的數(shù)據(jù)，請在這里界說你本身須要的長度，我每次讀一個字節(jié)進來unsignedlongnumBytesReturned;HIDD_ATTRIBUTESdevAttr;PHIDP_PREPARSED_DATAPreparsedData;HIDP_CAPSCapabilities;intreadValue;boolLED;intflag=0;

19、BytesReturned,0);temp=inbuffer;p->m_eDataRead=CString(inbuffer);p->UpdateData(false);if(!result1)AfxMessageBox("CannotReadData)return0;readValue=inbuffer1;p->m_eDataRead.Format("%d",readValue);/下面是我把數(shù)據(jù)從10進制轉(zhuǎn)換成二進制，并且點亮LED(一個字節(jié)有8個bits,可以點亮8個LEDor(intk=0;k<8;k+)flag=readValue

20、%2;readValue=readValue/2;if(k=0)if(flag=0)p->m_sDynLED0.SwitchOff();elsep->m_sDynLED0.SwitchOn();elseif(k=1)if(flag=0)p->m_sDynLED1.SwitchOff();elsep->m_sDynLED1.SwitchOn();elseif(k=2)if(flag=0)p->m_sDynLED2.SwitchOff();elsep->m_sDynLED2.SwitchOn();elseif(k=3)if(flag=0)p->m_sDyn
