return;

instance = this;
DontDestroyOnLoad(this.gameObject);

#region 创建串口，并打开串口

}`
这个串口是向USB发送串口相关信号的
项目中也用到了分屏，实际上就是弄出来2个Camera来，然后
我自己写了1个类来区分分屏
public class ActiveDisplay : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
//Screen.SetResolution(1920, 1080, true);
Display.displays[0].Activate();
Display.displays[0].SetRenderingResolution(1920, 1080);
if (Display.displays[1] != null)
{
Display.displays[1].Activate();
Display.displays[1].SetRenderingResolution(1920, 1080);
}
}
}
读写Json文件里边的一个自己写的一个类
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System.Text;
using LitJson;
using UnityEngine.UI;
public class JsonObjectModel
{
public List infoList{get;set;}
}
public class JsonArrayModel
{
public string Signal{get;set;}
public double Time{get;set;}
public byte[] Signalbyte { get; set; }
}
public class LoadJson : MonoBehaviour
{
public Button ButtonSend;
// Start is called before the first frame update
void Start()
{
StreamReader streamreader = new StreamReader(Application.dataPath + "/StreamingAssets/Info.json");
JsonReader js = new JsonReader(streamreader);//再转换成json数据
JsonObjectModel jsonObject=JsonMapper.ToObject<JsonObjectModel>(js);
foreach (var info in jsonObject.infoList)
{
Debug.Log(info.Signal + " " + info.Time + " ") ;
}
InitSendMsg(jsonObject);
// byte[] bytes = new byte[] { 0xA1 };
//StartCoroutine(SendMsgByTime(5.0, bytes));
for(int i=0;i<jsonObject.infoList.Count;i++)
{
int k = i;
StartCoroutine(SendMsgByTime(jsonObject.infoList[k].Time, jsonObject.infoList[k].Signalbyte));
}
}
IEnumerator SendMsgByTime(double deltaTime,byte[] bytes)
{
yield return new WaitForSeconds((float)deltaTime);
PortControl.Instance.WriteOneByte(bytes);
}
private void InitSendMsg(JsonObjectModel model)
{
for (int i = 0; i < model.infoList.Count; i++)
{
if (model.infoList[i].Signal == "A1")
model.infoList[i].Signalbyte = new byte[] { 0xA1 };
else if (model.infoList[i].Signal == "B1")
model.infoList[i].Signalbyte = new byte[] { 0xB1 };
else if (model.infoList[i].Signal == "C1")
model.infoList[i].Signalbyte = new byte[] { 0xC1 };
else if (model.infoList[i].Signal == "D1")
model.infoList[i].Signalbyte = new byte[] { 0xD1 };
else if (model.infoList[i].Signal == "A2")
model.infoList[i].Signalbyte = new byte[] { 0xA2 };
else if (model.infoList[i].Signal == "B2")
model.infoList[i].Signalbyte = new byte[] { 0xB2 };
else if (model.infoList[i].Signal == "C2")
model.infoList[i].Signalbyte = new byte[] { 0xC2 };
else if (model.infoList[i].Signal == "D2")
model.infoList[i].Signalbyte = new byte[] { 0xD2 };
}
}
// Update is called once per frame
void Update()
{
}
}
总结就差不多到这里了
