[openCV] 連結Arduino using Visual C++

要用CLR主控台應用程式，非Win32主控台應用程式，這樣才可以用System命名空間

• using namespace System;
• using namespace System::IO::Ports;

宣告comport，並指定portName與baudrate

• int baudRate = 9600;
• String^ portName = "COM5";
• SerialPort^ arduino;
• arduino = gcnew SerialPort(portName, baudRate);

用try catch處理Serialport

1. try
2. {
3. ....
4. }
5. catch (IO::IOException^ e  ) 
6. { 
7. Console::WriteLine(e->GetType()->Name+": Port is not ready");
8. }
9. catch (ArgumentException^ e)
10. {
11. Console::WriteLine(e->GetType()->Name+": incorrect port name syntax, must start with COM/com");
12. }

打開SerialPort

• arduino->Open();

傳送字串

• arduino->WriteLine(String);

關閉SerialPort

• arduino->Close();
