Как исправить проблему с Unity для последовательной связи Arduino через последовательный порт

0 голосов
/ 15 апреля 2019

Добрый день. У меня проблема с использованием единства с Arduino, я использую последовательный порт в качестве средства связи единства с Arduino. Я просто посылаю строки из единицы в Arduino.

После первого хода игрока происходит исключение IOException: Доступ запрещен ?. Я не могу играть во втором ходу игроков, потому что единство прекратилось после первого хода игрока. Затем выдает IOException: доступ запрещен

КОД ЕДИНСТВА 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using System.IO.Ports;

public class SceneManagement : MonoBehaviour
{

    SerialPort sp = new SerialPort("COM3", 9600);

    // Use this for initialization
    public void CountPlayer()
    {
        SceneManager.LoadScene("CountPlayer");
    }

    public void RandomSubject()
    {
        SceneManager.LoadScene("RandomSubject");
    }

    public void Game()
    {
        if (!sp.IsOpen)
        {
            sp.Open();
            sp.WriteTimeout = 100;
            Debug.Log("Port successfully opened");
        }
        sp.Write("green");
        SceneManager.LoadScene("Game1");
    }
}

Только один процесс может одновременно использовать определенный последовательный порт.

COM3 уже открыт SceneManagement , поэтому, когда другие запрашивают доступ к COM3, произойдет отказ в доступе.

Используйте класс менеджера для обработки объекта SerialPort или просто вызовите GetComponent<SceneManagement>().GetSP() чтобы получить существующий последовательный порт в других скриптах.
