Java RPi GPIO вопрос во время выполнения

Question

Мой код Это

package me.Andrew.Keypad.Listener; 

import java.util.HashMap; 

import com.pi4j.io.gpio.GpioController; 
import com.pi4j.io.gpio.GpioFactory; 
import com.pi4j.io.gpio.GpioPinDigitalInput; 
import com.pi4j.io.gpio.GpioPinDigitalOutput; 

import me.Andrew.Keypad.Main; 

public class ButtonInput { 
    public boolean isRunning = false; 
    public GpioController gpio = GpioFactory.getInstance(); 
    Main MA = Main.getInstance(); 

    public HashMap<String, GpioPinDigitalInput> ColPins = null; 
    public HashMap<String, GpioPinDigitalOutput> RowPins = null; 

    public void start() { 
     isRunning = true; 
     ButtonListener(); 
    } 

    public void stop() { 
     isRunning = false; 
    } 

    private int ScanRow(int row) { 
     int Col = 0; 
     RowPins.get(String.valueOf(row)).high(); 
     if (ColPins.get("1").isHigh()) { 
      Col = 1; 
     } else if (ColPins.get("2").isHigh()) { 
      Col = 2; 
     } else if (ColPins.get("3").isHigh()) { 
      Col = 3; 
     } else if (ColPins.get("4").isHigh()) { 
      Col = 4; 
     } 
     return Col; 
    } 

    private void ButtonListener() { 

     Main.GPIOMeths.setupPins(); 
     RowPins = Main.store.RowPins; 
     ColPins = Main.store.ColPins; 

     int Response = 0; 

     while (isRunning == true) { 
      if (isRunning) { 
       Response = ScanRow(1); 

       if (Response == 1) { 
        stop(); 
        buttonPressEvent("1"); 
        break; 
       }else if (Response == 2) { 
        stop(); 
        buttonPressEvent("2"); 
        break; 
       }else if (Response == 3) { 
        stop(); 
        buttonPressEvent("3"); 
        break; 
       }else if (Response == 4) { 
        stop(); 
        buttonPressEvent("A"); 
        break; 
       } 

       int Responsee = ScanRow(2); 
       if (Responsee != 0) { 
        stop(); 
        String BP = Main.Meths.getButton(2, Responsee); 
        buttonPressEvent(BP); 
        break; 
       } 

       int Responseee = ScanRow(3); 
       if (Responseee != 0) { 
        stop(); 
        String BP = Main.Meths.getButton(3, Responseee); 
        buttonPressEvent(BP); 
        break; 
       } 

       int Responseeee = ScanRow(4); 
       if (Responseeee != 0) { 
        stop(); 
        String BP = Main.Meths.getButton(4, Responseeee); 
        buttonPressEvent(BP); 
        break; 
       } 
      } 

     } 
    } 

    public void buttonPressEvent(String ButtonPressed) { 
     // String ButtonPressed = Main.Meths.getButton(Row, Col); 
     if (ButtonPressed.equalsIgnoreCase("*")) { 
      System.out.println("Code Logging Started"); 
      Main.store.CodeMode = true; 
      Main.store.CodeEntered = ""; 
     } else if (ButtonPressed.equalsIgnoreCase("#")) { 
      System.out.println("Code Logging Ended"); 
      if (Main.Meths.CompareCodes()) { 
       System.out.println("Code Correct"); 
      } else { 
       System.out.println("Code Incorrect"); 
      } 
      Main.store.CodeMode = false; 
     } else { 
      if (Main.store.CodeMode == false) { 
       System.out.println("Code Logging Not Running: " + ButtonPressed); 
      } else { 
       Main.store.CodeEntered = Main.store.CodeEntered + ButtonPressed; 
       System.out.println("Code Entered: " + Main.store.CodeEntered); 
      } 
     } 
     try { 
      Thread.sleep(500); 
     } catch (InterruptedException e) { 
     } finally { 
      start(); 
     } 

    } 
} 

Но когда я запустить его и нажать 1,2,3, А все из верхней строки я получаю этот ответ

корень @ raspberrypi :/главная/пи # ява -jar /home/pi/keypad.jar код Logging не работает: 7 Код Logging Not Running: 0 Код Logging не работает: 9 Код Logging Not Running: A

Answer 1

Добавлено

RowPins.get(String.valueOf(row)).low(); 

В конце строки развертки
