串口读数据 [英] Serial port reading data

问题描述

我设计了一个应用程序以进行数据交换，我在C＃中开发了一个应用程序，我也可以发送和接收数据，但问题是我将数据作为字符ASCII。我希望逐字节地接收HEX中的数据，我在网上搜索但是我还没有找到解决方案，所以我想如果有人帮助以及如何接收数据IN六进制字节。



这是我接收数据的代码

  String 数据; 
  private   void  serialPort1_DataReceived（ object  sender，SerialDataReceivedEventArgs e）
 {
 data + = serialPort1.ReadExisting（）; 
  this  .Invoke（ new  EventHandler（display_data_event））; 
} 
 
  private   void  display_data_event（ object  sender，EventArgs e）
 {
 textBox2.Text = data; 
} 

解决方案

然后停止以字符串形式读取数据，并将其作为字节读取： SerialPort.Read方法（Byte []，Int32，Int32）（System.IO.Ports） [ ^

Hi, I designed an application in order to make data exchange , I developed an application in C # , I can sent and receive data as well, but the problem is that I get the data as character ASCII . I would like to receive the data in HEX byte by byte , I searched the in the net but I have not found a solution , so I would like if some one help and how to receive the data IN hexa byte .

Here is my piece of code to receive the data

String data;
    private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        data += serialPort1.ReadExisting();
        this.Invoke(new EventHandler(display_data_event));
    }
 
    private void display_data_event(object sender, EventArgs e)
    {
        textBox2.Text = data;
    }

解决方案

Then stop reading the data as a string, and read it as bytes: SerialPort.Read Method (Byte[], Int32, Int32) (System.IO.Ports)[^]
