usb上位機(jī)開發(fā)筆記

的MFC上位機(jī)開發(fā)，挺長的，沒學(xué)完，學(xué)了一點(diǎn)皮毛，然后今年開工，前前后后經(jīng)過2個(gè)多星期的折騰，終于開發(fā)了一個(gè)最基本的USB上位機(jī)。開發(fā)過程中一直是迷迷糊糊，開發(fā)完了一總結(jié)，發(fā)現(xiàn)也就那么回事， 了非常多的時(shí)間去調(diào)試，去進(jìn)行面向的編程，最后迫不得已，還花錢請了USBCypressFX3開發(fā)套件里面提供的源碼，絕對是安全可靠的，里面具體用到了哪些知說明手冊才能理解。這部分內(nèi)容，小梅哥也會(huì)在后期以短片的形式和大家一起學(xué)習(xí)。 FX3SDK\1.3\library下的cpp拷貝到工程 下并改名為USBLIB假設(shè)工程名為XLH_USB_Console.vcxproj路徑為：D:\XLH_USB\XLH_USB_Console\路徑為:則包 為：..\附加依賴項(xiàng)：..\ USBLIB\lib\x86\CyAPI.lib“..\” ?！?\”則 CButtonm_StartBtn;CButtonm_FindDevBtn;CComboBoxm_cboDevices;CButtonm_StartBtn;CButtonm_FindDevBtn;CComboBoxm_cboDevices;CComboBoxDDX_Control(pDX,IDC_START,m_StartBtn);DDX_Control(pDX,IDC_FINDDEV,m_FindDevBtn);DDX_Control(pDX,IDC_DEV_LIST,m_cboDevices);DDX_Control(pDX,IDC_START,m_StartBtn);DDX_Control(pDX,IDC_FINDDEV,m_FindDevBtn);DDX_Control(pDX,IDC_DEV_LIST,m_cboDevices);xxxxDlg.h中,添加 ludexxxxDlg.h中,CCyUSBDevice*m_selectedUSBDevice;//USB設(shè)備CCyUSBEndPoint*OutEndpt;//USB m_selectedUSBDevicem_selectedUSBDevicenewCCyUSBDevice(this->m_hWnd,CYUSBDRV_GUID,true);//創(chuàng)建USB設(shè)BOOL{CCyUSBDeviceUSBDevice=newCCyUSBDevice(this->m_hWnd,CYUSBDRV_GUID,true);CStringstrDevice(L"");intnCboIndex=-if(m_cboDevices.GetCount()>0)m_cboDevices.GetWindowText(strDevice);if(USBDevice!={intnInsertionCount=intnDeviceCount=USBDevice-for(intnCount=0;nCount<nDeviceCount;{CStringstrDeviceData;strDeviceData.Format("(0x%04X-0x%04X)%s",USBDevice->VendorID,USBDevice->ProductID,CString(USBDevice->FriendlyName));if(USBDevice->bHighSpeed)strDeviceData+="(HighSpeed)";elseif(USBDevice->bSuperSpeed)strDeviceDataelseif(USBDevice->bSuperSpeed)strDeviceData+="(SuperSpeed)";if(nCboIndex==-1&&strDevice.IsEmpty()==FALSE&&strDevice==nCboIndex=}deleteif(m_cboDevices.GetCount()>={if(nCboIndex!=-1)m_cboDevices.SetCurSel(nCboIndex);elsem_cboDevices.SetCurSel(0);}}elsereturnreturn}BOOL{intnDeviceIndex=if((nDeviceIndex=m_cboDevices.GetCurSel())==-1||m_selectedUSBDevice==NULL)returnFALSE;intinterfaces=this->m_selectedUSBDevice->AltIntfcCount()+for(intnDeviceInterfaces=0;nDeviceInterfaces<interfaces;{ tm_selectedUSBDevice 點(diǎn) for(intendPoint=1;endPoint t;{ //INTR,BULKandISOendpointsaresupported.if(ept->Attributes==2){CStringstrData(L""),strData+=((ept->Attributes==1)?"ISOC":((ept->Attributes==2)?"BULK":"INTR"));strData+=(ept->bIn?"IN,":"OUT,strTemp.Format("%dBytes,",ept->MaxPktSize);strData+=strTemp;{strTemp.Format("%dMaxBurst,",ept->ssmaxburst);strData+=strTemp;}strTemp.Format("AltInt-%dandEpAddr-0x%02X",nDeviceInterfaces,ept->Address);strData+=if(ept->bIn)this->m_cboEndpointIN.AddString(strData);elsethis->m_cboEndpointOUT.AddString(strData);}}}if(m_cboEndpointOUT.GetCount()>0)if(m_cboEndpointIN.GetCount()>return}#defineUSB30voidvoid{}voidvoid{}基于USBCWinThread*XferThread; CWinThread*XferThread; boolbLoo {#defineXFEROVERLAPPEDoutOvLap,CXLH_USB_ConsoleDlg*dlg=(CXLH_USB_ConsoleDlgPUCHARinData=newUCHAR[XFER]; ZeroMemory(inData,XFER);inOvLap.hEvent=CreateEvent(NULL,false,false,dlg->OutEndpt->TimeOut=boolsuccess,success1;HANDLEhFile=CreateFile("usb_data.bin",GENERIC_WRITE,NULL,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL); t=LONGDATA_SIZE=dlg->GetDlgItemInt(IDC_RCVLEN);for(;dlg->bLoo ;){LONGoutlen,inlen,len;outlen=inlen=len=XFER;DWORDdwret=UCHARUCHAR ontext=dlg->InEndpt->BeginDataXfer(inData,inlen,success1=dlg->InEndpt->FinishDataXfer(inData,inlen, if(success1){DWORDdwret=0;t= t+inlen;WriteFile(hFile,inData,len,&dwret,NULL);if(dwret!=XFER){ =}if{t>= =}}}delete[]inData;dlg->XferThread=NULL;return}voidvoid{if{bLoo }}elseintn=m_selectedUSBDevice-intDeviceIndex=m_cboDevices.GetCurSel();if(DeviceIndex==0xffffffff)if(n!={CStringstrINData,strOutData;char*pEnd;strINData=strINData.Right(4);strOutData=strOutData.Right(4);inAddr=(BYTE)strtoul(strINData.GetBuffer(0),&pEnd,16);outAddr=(BYTE)strtoul(strOutData.GetBuffer(0),&pEnd,16);InEndpt=m_selectedUSBDevice->EndPointOf(inAddr);{ =XferThread=}}}}始傳輸，速度很快，幾乎看不到任何延遲，在工程根下就已經(jīng)出現(xiàn)了一個(gè)名為
