Processing: Class JSerialSelector – Science To Medicine

今回、Processing 3での、シリアル通信を容易に設定するために、SerialSelectorクラスを作成した。
Processing 3での作動や実行型ファイルへの変換（Application Export）でハングしてしまうControlP5ライブラリの使用は避けて、Java SwingでGUIは構築した。setup()関数内で以下のように、SerialSelectorクラスのインスタンスを生成して、通信条件の初期値をクラス内のインスタンス変数に設定していく。
JSerialSelector.pde

void setup(){
..................
  selector = new JSerialSelector();
  selector.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  selector.combo_port.setSelectedIndex(1);
  selector.combo_baud_rate.setSelectedItem("19200");
  selector.combo_parity.setSelectedItem('N');
  selector.combo_data_bits.setSelectedItem("8");
  selector.combo_stop_bits.setSelectedItem("1");

  selector.setBounds(10, 10, 440, 550);
  selector.setTitle("Serial Port & Mode");
