二、核心代码实现

1. 主程序入口 (Program.cs)

using System;
using System.Windows.Forms;

namespace SerialFlashTool
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            
            // 检查管理员权限
            if (!IsAdministrator())
            {
                MessageBox.Show("建议以管理员权限运行此程序，以确保串口访问正常。", 
                    "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            
            Application.Run(new MainForm());
        }
        
        private static bool IsAdministrator()
        {
            try
            {
                var identity = System.Security.Principal.WindowsIdentity.GetCurrent();
                var principal = new System.Security.Principal.WindowsPrincipal(identity);
                return principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator);
            }
            catch
            {
                return false;
            }
        }
    }
}

三、使用说明

1. 硬件连接

将开发板的串口连接到电脑
确保开发板进入Bootloader模式
- STM32: BOOT0拉高，复位
- ESP32: GPIO0拉低，复位
连接电源

2. 软件操作

运行SerialFlashTool.exe
选择串口和波特率
选择协议类型
点击"浏览"选择Bin文件
设置烧写参数
点击"开始烧写"

3. 支持的芯片

STM32系列: F0/F1/F2/F3/F4/F7/H7
ESP32系列: ESP32/ESP32-C3/ESP32-S3

4. 常见问题

问题	解决方法
无法打开串口	检查串口是否被占用，以管理员身份运行
检测不到芯片	检查Boot模式，确认硬件连接
烧写失败	降低波特率，检查电源电压
校验失败	检查Flash大小，重新编译固件
