Strange Serial Input
I seem to be getting very weird serial input for Dashboard3D. For example, when the robot/control board is not on/connected, I get 48 for the packet number, 176 for p2wheel, 48 for ctrl-A, etc. I don't understand... Also, when everything is connected and running, I seem to get very odd numbers. I might be doing something wrong but I don't know...
Here is the serial init code (keep in mind that it is in a bool function in a class structure): HANDLE hfSerial; COMMTIMEOUTS m_CommTimeouts; hfSerial=CreateFile(Comm,GENERIC_READ,0,0,OPEN_EXI STING,FILE_ATTRIBUTE_NORMAL,0); if(hfSerial==INVALID_HANDLE_VALUE) { if(GetLastError()==ERROR_FILE_NOT_FOUND){return false;} } SetupComm(hfSerial,128,128); DCB dcbSerialParams; ZeroMemory(&dcbSerialParams,sizeof(dcbSerialParams )); dcbSerialParams.DCBlength=sizeof(dcbSerialParams); if(!GetCommState(hfSerial,&dcbSerialParams))return false; dcbSerialParams.BaudRate=CBR_19200; dcbSerialParams.ByteSize=8; dcbSerialParams.StopBits=ONESTOPBIT; dcbSerialParams.Parity=NOPARITY; if(!SetCommState(hfSerial,&dcbSerialParams))return false; if(!GetCommTimeouts(hfSerial, &m_CommTimeouts))return false; m_CommTimeouts.ReadIntervalTimeout = 50; m_CommTimeouts.ReadTotalTimeoutConstant = 50; m_CommTimeouts.ReadTotalTimeoutMultiplier = 10; m_CommTimeouts.WriteTotalTimeoutConstant = 50; m_CommTimeouts.WriteTotalTimeoutMultiplier = 10; if(!SetCommTimeouts(hfSerial, &m_CommTimeouts))return false; hSerial=hfSerial; strcpy(cComm,Comm); bConnected=true; _beginthread(SerialThread,0,NULL); return true; |
