C# 串口实现空闲接收中断功能

设置接收超时毫秒数ReadTimeout
线程接收，每次读一个字节，添加到列表中
接收超时时，捕获异常，生成一帧数据
啥也不说了，看代码

private void Form1_Load(object sender, EventArgs e)
{
var sList = SerialPort.GetPortNames();
this.serialPort1.PortName = sList.Last();
this.serialPort1.BaudRate = 9600;
this.serialPort1.ReadTimeout = 10;
this.serialPort1.Open();
thread = new Thread(new ThreadStart(ThreadReceive));
thread.Start();
timer1.Start();

}

Queue<List<byte>> queueList = new Queue<List<byte>>();
Thread thread = null;
List<byte> receiveList = new List<byte>();
void ThreadReceive()
{

while (true)
{
try
{
int data = this.serialPort1.ReadByte();
if (data >= 0)
receiveList.Add((byte)data);
}
catch
{
if (receiveList.Count > 0)
{
queueList.Enqueue(receiveList);
receiveList = new List<byte>();
}
}
}
}
