Any one know how my program should be like when i need to pass in information for example "a" and display it in a display box... through serial communication.
erm... i did the codings... its like this...
void CSerialComm::Send(HANDLE *pComm, CString str) { unsigned char StopByte=0x1; unsigned long int n_out; str = "0x80"; WriteFile(*pComm, str, str.GetLength(),&n_out , NULL); WriteFile(*pComm, &StopByte, 1, &n_out, NULL); } void CSerialComm::Receive(HANDLE *pComm, CString str1) { char cRxByte; DWORD dwRead; while(cRxByte!=0x1) { ReadFile(*pComm, &cRxByte, 1, &dwRead, NULL); str1+=cRxByte; } MessageBox("Acknowledge Received"); // MessageBox(str1); } void CSerialComm::initComm(HANDLE *pComm) { // HANDLE hComm; // hComm = CreateFile( "COM1:", // GENERIC_READ | GENERIC_WRITE, // 0, // 0, // OPEN_EXISTING, // FILE_FLAG_OVERLAPPED, // 0); // if (hComm == INVALID_HANDLE_VALUE) // { // } // error opening port; abort *pComm = CreateFile("COM1:", GENERIC_WRITE|GENERIC_READ, 0, NULL, OPEN_EXISTING, 0, NULL); if (*pComm ==INVALID_HANDLE_VALUE) { //MessageBox("Please input value !"); } //FillMemory(&dcb, sizeof(dcb), 0); dcb.DCBlength = sizeof(dcb); dcb.BaudRate = CBR_9600; dcb.fBinary = TRUE; dcb.fDtrControl = DTR_CONTROL_DISABLE; dcb.fRtsControl = RTS_CONTROL_DISABLE; dcb.ByteSize = 8; dcb.Parity = NOPARITY; dcb.StopBits = ONESTOPBIT; if (!SetCommState(*pComm, &dcb)) { //MessageBox("Wrong Port"); } }
"tell me wats wrong..." You're asking in the wrong forum, that's what's wrong! That's PC code - so you need to ask about it in a PC forum! What have you done to debug it? MSVC includes a debugger!
Yes indeed it's the wrong forum. However I could send you a functionnal sample so at least you could try to solve your micro-controller communications problems with people sharing there knowledge on this forum (however HyperTerminal is enough for this purpose...). For this I need an e-mail. Jean-Pierre
