C# WPF读写STM32/GD32单片机Flash数据

1.安装jlink

下载你需要的Jlink版本

JLink-Windows-V792k-x86-64

JLink-Windows-V810k-x86-64

https://download.csdn.net/download/hmxm6/90178195

2.Visual Studio创建WPF项目

如果没有这个选项请看

https://blog.csdn.net/hmxm6/article/details/132914337

创建完成后

添加一些界面

MainWindow.xaml

<Window x:Class="Jlink_Demo.Views.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:prism="http://prismlibrary.com/"prism:ViewModelLocator.AutoWireViewModel="True"Title="{Binding Title}" Height="350" Width="525" ><Grid><StackPanel Width="525" Height="350" HorizontalAlignment="Left"><Button Width="100"  Height="30"  Command="{Binding connectJlink}">连接Jlink</Button><Button  Width="100"  Height="30"  Command="{Binding closeJlink}">关闭Jlink连接</Button><TextBlock Width="200" Text="{Binding JLINKVersion}" FontSize="20"></TextBlock><Button Width="100" Height="30" Command="{Binding connectMCU}">连接MCU</Button><TextBlock Width="200" Text="{Binding HardwareId}" FontSize="20"></TextBlock><Button Width="100" Height="30" Command="{Binding resetMCU}">复位单片机</Button><Button Width="100" Height="30" Command="{Binding readFlash}">读取Flash</Button><Button Width="100" Height="30" Command="{Binding writeFlash}">写入Flash</Button><TextBox  Width="100" FontSize="20" Text="{Binding FlashData}"></TextBox></StackPanel></Grid>
</Window>

添加MVVM变量

MainWindowViewModel.cs

using Prism.Mvvm;namespace Jlink_Demo.ViewModels
{public class MainWindowViewModel : BindableBase{// 标题 MVVMprivate string _title = "Prism Application";public string Title{get { return _title; }set { SetProperty(ref _title, value); }}// Jlink版本 MVVMprivate string _JLINKVersion = "Jlink版本:";public string JLINKVersion{get { return _JLINKVersion; }set { SetProperty(ref _JLINKVersion, value); }}// 硬件ID MVVMprivate string _HardwareId = "硬件ID:";public string HardwareId{get { return _HardwareId; }set { SetProperty(ref _HardwareId, value); }}// Flash数据 MVVMprivate int _FlashData = 0;public int FlashData{get { return _FlashData; }set { SetProperty(ref _FlashData, value); }}public MainWindowViewModel(){}}
}

3.加入jlink dll

在Jlink安装目录下有两个dll文件,请选择对应dll文件

把文件放入项目

文件属性中，选择始终复制

4.添加jlink工具类

}

5.编写按钮事件

MainWindowViewModel.cs

连接c并读取JLink版本号

private DelegateCommand _connectJlink;
public DelegateCommand connectJlink => _connectJlink ?? (_connectJlink = new DelegateCommand(ExecuteConnectJlink));void ExecuteConnectJlink()
{// 1.打开jlinkJLink.JLINKARM_Open();// 读取jlink版本号var dllVersion = JLink.JLINKARM_GetDLLVersion();var hardVersion = JLink.JLINKARM_GetHardwareVersion();this.JLINKVersion = "JLink版本号:" + hardVersion;
}

关闭连接JLink

private DelegateCommand _closeJlink;
public DelegateCommand closeJlink => _closeJlink ?? (_closeJlink = new DelegateCommand(ExecuteCloseJlink));void ExecuteCloseJlink()
{JLink.JLINKARM_Close();// 关闭jlinkthis.JLINKVersion = "";this.HardwareId = "";
}

连接单片机

private DelegateCommand _connectMCU;
public DelegateCommand connectMCU => _connectMCU ?? (_connectMCU = new DelegateCommand(ExecuteConnectMCU));void ExecuteConnectMCU()
{if (JLink.JLINKARM_IsOpen() == true){JLink.JLINKARM_TIF_Select(1);// SWD连接方式// 连接STM32F407VGJLink.JLINKARM_ExecCommand(System.Text.Encoding.UTF8.GetBytes("device = STM32F407VG"), 0, 0);JLink.JLINKARM_SetSpeed(4000);Thread.Sleep(100);//休眠时间var id = JLink.JLINKARM_GetId();// 判断单片机连接状态if (JLink.JLINKARM_IsConnected() == true){// 通过MVVM设置界面上的单片机IDthis.HardwareId = "SUCCESS id:" + id;}else{this.HardwareId = "ERROR";}}else{MessageBox.Show("请先打开烧录器");}
}

复位单片机

private DelegateCommand _resetMCU;
public DelegateCommand resetMCU => _resetMCU ?? (_resetMCU = new DelegateCommand(ExecuteResetMCU));void ExecuteResetMCU()
{JLink.JLINKARM_Reset();JLink.JLINKARM_Go();
}

读取Flash数据

private DelegateCommand _readFlash;
public DelegateCommand readFlash => _readFlash ?? (_readFlash = new DelegateCommand(ExecuteReadFlash));void ExecuteReadFlash()
{UInt32 dataBuff = 0;byte status = 0;if (JLink.JLINKARM_IsConnected() == true){// 读取Flash数据JLink.JLINKARM_ReadMemU32(0x080F0000, 1, ref dataBuff, ref status);// 判断读取状态if (status == 0){// 通过MVVM设置界面上的值this.FlashData = (int)dataBuff;}else{this.FlashData = 0;}}}

写入Flash数据

private DelegateCommand _writeFlash;
public DelegateCommand writeFlash => _writeFlash ?? (_writeFlash = new DelegateCommand(ExecuteWriteFlash));void ExecuteWriteFlash()
{if (JLink.JLINKARM_IsConnected() == true){JLink.JLINKARM_WriteU32(0x080D0000, (uint)this.FlashData);}
}
