分享CSerialPort串口类初始化Initport（）出错
m_SerialPort.InitPort(this,nPort,9600,"N",8,1,EV_RXFLAG|EV_RXCHAR,512)连接时提示：
error C2664: 'InitPort' : cannot convert parameter 4 from 'char [2]' to 'char'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
请高手指点一下！

提示应该是数据类型转换时的错误，参考一下hCom的设置：
HANDLE hCom =::CreateFile( _T("\\\\.\\COM11"), //打開串口
GENERIC_READ|GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
0,//FILE_FLAG_OVERLAPPED,
0
);
if(hCom ==INVALID_HANDLE_VALUE) //判斷串口是否打開
{
DWORD dwError=::GetLastError();
return false;
}
这边是测试OK!
HANDLE hCom =::CreateFile( _T("\\\\.\\COM11"), //打開串口
GENERIC_READ|GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
0,//FILE_FLAG_OVERLAPPED,
0
);
if(hCom ==INVALID_HANDLE_VALUE) //判斷串口是否打開
{
DWORD dwError=::GetLastError();
return false;
}
这边是测试OK!

"N"改成'N'即可
BOOL CSerialPort::InitPort()第四个参数为char parity

"N"用'N'或者NULL代替

CSerialPort.cpp中是这样的：
m_hComm = CreateFile(szPort, // communication port string (COMX)
GENERIC_READ | GENERIC_WRITE, // read/write types
0, // comm devices must be opened with exclusive access
NULL, // no security attributes
OPEN_EXISTING, // comm devices must use OPEN_EXISTING
FILE_FLAG_OVERLAPPED, // Async I/O
0);
m_hComm = CreateFile(szPort, // communication port string (COMX)
GENERIC_READ | GENERIC_WRITE, // read/write types
0, // comm devices must be opened with exclusive access
NULL, // no security attributes
OPEN_EXISTING, // comm devices must use OPEN_EXISTING
FILE_FLAG_OVERLAPPED, // Async I/O
0);
