unity脑电游戏的制作-脑电的获取步骤三
作者:互联网
在unity中的代码
在unity工程中新建一个脚本,脚本中的代码如下:
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO.Ports;
using System.Threading;
using UnityEngine;
using UnityEngine.UI;
public class connect : MonoBehaviour
{
public SerialPort COM = new SerialPort();//初始化serialport类的新实例,用于获取串行端口资源
public Text PoorSignal;
public Text Attention;
public Text Meditation;
void Start()
{
COM.BaudRate = 9600;//波特率
COM.PortName = "COM3";//端口名
COM.DataBits = 8;//数据位
COM.ReadTimeout = 5000;
COM.Open();//打开一个新的串行端口连接
StartCoroutine(DataReceived());
// COM.DataReceived += new SerialDataReceivedEventHandler(COM_DataReceived);
}
IEnumerator DataReceived()
{
while(true)
{
Rec();
yield return new WaitForSeconds(0.5f);
}
}
/// <summary>
/// 脑电的获取
/// </summary>
private void Rec()
{
try
{
int n = COM.BytesToRead;
byte[] numArray = new byte[this.COM.BytesToRead];
COM.Read(numArray, 0, n);
if (numArray.Length == 0)
return;
else
{
Debug.Log("numarry长度是:" + numArray.Length);
}
if (numArray[0] == (byte)170 && numArray[1] == (byte)170)
{
Debug.Log("进入");
if(numArray.Length==36)
{
int num = 0;
num = Convert.ToInt32(numArray[4]);
Debug.Log("信号值是:" + num);
PoorSignal.text= num.ToString();
int attention = 0;
attention = Convert.ToInt32(numArray[32]);
Debug.Log("专注值是:" + attention);
Attention.text = attention.ToString();
int meditation = 0;
meditation= Convert.ToInt32(numArray[34]);
Debug.Log("放松值是:" + meditation);
Meditation.text = meditation.ToString();
else
{
return;
}
}
COM.DiscardInBuffer();
}
catch (Exception ex)
{
throw ex;
}
}
public void ClosePort()
{
try
{
COM.Close();
}
catch(Exception ex)
{
Debug.Log(ex.Message);
}
}
private void OnApplicationQuit()
{
ClosePort();
}
}
运行时会出现的问题:
1.命名空间的引入:
在下面界面中选择程序包,安装using System.IO.Ports程序包。
2.unity中需要进行相关的设置:
将Api Compatibility Level设置为4.0,相对应的命名空间才能正确引入。
完成以上步骤,就可以从脑电设备中获取数据,并在unity中进行使用开发。
