Простое java приложение Raspberry Pi, использующее библиотеку Netbeans и Pi4J, не просыпается после сборки - PullRequest

/ 19 февраля 2020

Есть ли кто-нибудь, кто может помочь мне с этим вопросом? Когда я запускаю приложение Java непосредственно на NetBeans, оно работает на 100% нормально. Я могу контролировать светодиод. Но когда я собираю проект и запускаю встроенный файл jar, приложение появляется, но кажется, что оно не может управлять светодиодом, когда я нажимаю кнопку.

Исходный код:

package pi4j_led;

import com.pi4j.io.gpio.GpioController;
import com.pi4j.io.gpio.GpioFactory;
import com.pi4j.io.gpio.GpioPinDigitalOutput;
import com.pi4j.io.gpio.PinState;
import com.pi4j.io.gpio.RaspiPin;
import java.util.logging.Level;
import java.util.logging.Logger;

public class mainWindow extends javax.swing.JFrame {

    //create GPIO Controller
    final GpioController gpio = GpioFactory.getInstance();

    //provision gpio pin #01 as an output pin and turn on
    final GpioPinDigitalOutput pin = gpio.provisionDigitalOutputPin(RaspiPin.GPIO_01, "My LED", PinState.HIGH);



    public mainWindow() {
        initComponents();
        pin.setShutdownOptions(true);
    }
