C＃中的串口转换器进程 [英] Serial Port Converter Process in C#

问题描述

我正在研究串口转换器进程。如何将串口转换器连接到C＃编码。任何人都可以给我一个解决方案。

您需要创建并打开连接到机器的SerialPort实例，并从中读取数据 - 然后您可以将其转换为您的班级可以返回的权重。



查看MSDN页面：SerialPort类 [ ^ ] - 它包含一个基本的通信示例。

使用System;

使用System.Linq;

使用System.Data;

使用System.Text;

使用System.Drawing;

使用System.IO.Ports;

使用System.Windows.Forms;

使用System.ComponentModel;

使用System.Collections.Generic;

使用Converter.Properties;

使用System .Threading;

使用System.IO;

使用System.Data.OleDb;

Hi,
I''m working on Serial Port Converter Process.How to connect serial port converter to C# coding.Can any one give me a solution for this.

You need to create and open a SerialPort instance connected to the machine, and read the data from it - you can then convert that into weights which your class can return.

Look at the MSDN page: SerialPort Class[^] - it includes a basic example of communications.
