求代碼單片機溫室監控管理系統上位機C#程序(VS2008)仿真與源程序設計

ID:430780 · 發表于 2019-3-18 10:06

基于51單片機的溫室控制與管理系統仿真設計（源程序+仿真文件）分享！

實物電路中MAX232與8051的連接方法:
(1) MAX232的11腳(TIN)接8051的P3.1(TXD)
(2) MAX232的12腳(R1OUT)接8051的P3.0(RXD)
通過上位機控制時,設COM3,COM4對連

仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

上位機C#程序(VS2008)源程序如下:

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
