LsCommDemo(for vc6)演示了多线程串口类CComPort的使用

How to use LsComm LsComm is a multiThread Com class that is written by me(Liu_sir). Main idea of me is to write a Easy to Use Com class. You can write a little Code and finish the Communication with high Efficency,It is what I want to do. there are three Receiving modes of LsComm: 1.ManualReceiveByQuery 2.ManualReceiveByConst 3.AutoReceiveBySignal 4.AutoReceiveByBreak I have writen a Demo Program for the usage of the 4 types of mode; there are some Examples: 1.ManualReceiveByQuery #include "ComPort.h" LsComm::CComPort m_ComPort;//LsComm is namespace in c++ m_ComPort.Open(2,LsComm::CComPort::AutoReceiveByquery); //ReCeive Com Data: DWORD InBufferCount; byte pbuffer[2048]; InBufferCount = m_ComPort.GetInBufferCount(); if(InBufferCount>0) { m_ComPort.GetInput(pbuffer,InBufferCount); } //Write Com Data: char a[10]; CString c; for(int i=0;i<10;i++) { a[i]='b'; c+=a[i]; c+=" "; } this->m_ComPort.Output(a,sizeof(a)); 2.ManualReceiveByConst(it is a ASsync mode) #include "ComPort.h" LsComm::CComPort m_ComPort;//LsComm is namespace in c++ m_ComPort.Open(2,LsComm::CComPort::AutoReceiveByConst); //ReCeive Com Data: DWORD InBufferCount=0; byte pbuffer[2048]; InBufferCount=this->m_ComPort.GetInput(pbuffer,10,1000); //above ,I want to Get 10 Bytes in 1 Second //Certainly You Can modify these Params;for example //InBufferCount=this->m_ComPort.GetInput(pbuffer,100,2000); //InBufferCount return the real bytes in Com Receiving Buffer you have Got; if(InBufferCount==0) return; CString c; char a[4]; for(int i=0;i<(int)InBufferCount;i++) { ::sprintf(a,"%2.2X",pbuffer[i]); c+=a; c+=" "; } c="接收(Receive):"+c; //Write Com Data: char a[10]; CString c; for(int i=0;i<10;i++) { a[i]='b'; c+=a[i]; c+=" "; } this->m_ComPort.Output(a,sizeof(a)); /*before use the 3,4 mode,You must write a receive a Funcion witch will be called back in Lscomm. */ void OnReceiveData(LPVOID pSender,void* pBuf,DWORD InBufferCount) { CString c; byte a[100]; char b[4]=""; memcpy(a,pBuf,InBufferCount); CLsCommDemoDlg* pDlg = (CLsCommDemoDlg*) pSender; CListBox*pList =(CListBox*)pDlg->GetDlgItem(IDC_LIST1); for(int i=0;i<(int)InBufferCount;i++) { ::sprintf(b,"%2.2X",a[i]); c+=" "; c+=b; } c="接收(Receive):"+c; pList->AddString(c); } 3.AutoReceiveBySignal #include "ComPort.h" LsComm::CComPort m_ComPort;//LsComm is namespace in c++ m_ComPort.Open(2,LsComm::CComPort::AutoReceiveBySignal ); m_ComPort.SetReceiveFunc((FOnReceiveData)OnReceiveData,this); m_ComPort.SetBreakHandleFunc(OnComBreak); //ReCeive Com Data: in OnReceiveData(LPVOID pSender,void* pBuf,DWORD InBufferCount) //above //write data the same as the first mode; 4.AutoReceiveByBreak #include "ComPort.h" LsComm::CComPort m_ComPort;//LsComm is namespace in c++ m_ComPort.Open(2,LsComm::CComPort::AutoReceiveByBreak ); m_ComPort.SetReceiveFunc((FOnReceiveData)OnReceiveData,this); m_ComPort.SetBreakHandleFunc(OnComBreak); //ReCeive Com Data: in OnReceiveData(LPVOID pSender,void* pBuf,DWORD InBufferCount) //above //write data the same as the first mode; You can add Break deal function in each mode but you can remove it if it is no use: void OnComBreak(LPVOID pSender,DWORD dwMask,COMSTAT stat) { //deal with the break of com here } Extra: I am a chinese,and My English is Poor.I am very sorry I can,t write fluent illumination for you. Special Thanks: for PJ Naughter ,He write a Excellent Com CLass:CSerialPort witch I have used in my Program. liu_sir 2003.5
