STM32F103C8T6核心板 如何上载程序

一、焊接好下载好后

二、连接ST-LINK V2

ST-LINK V2 STM32

3.3V 3V3

SWDIO SWIO

SWCLK SWCLK

GND GND

三、下载好keil5 MDK 版

计算机的，下载的软件应该很简单吧

四、安装驱动

先下载驱动

插上你的调试器，下载好打开下图这个，一直next就好，然后打开设备管理器

五、打开一个现成的工程昌弯塌

出现什么乱七八糟的先不要理他，后面我们慢慢调

六、配置

点击小魔术棒，找到debug，先找flash downlode

也可以去官网下载。

下载好后

file------------>import-------------------->找到刚刚下载的东西

一直next就好，前提你得安装好MDK版的keil5

Flash文件夹下就会多了很多东西

重新打开keil5，小魔术棒找到debug,进入setting，再选择debug，跟着选择这几个，闹宏点确定和OK，之后，如耐圆果出现，这是因为目标板的芯片处于休眠的状态，按复位键（板子上的小红色按键），再重新编译和下载就好，这样就是成功了的，现在可以看到板子一闪一闪的了。

1、 首先安装ST官方串口下丛斗载软件，

Flash_Loader_Demonstrator_v2.2.0_Setup.exe

2、 用交叉串口渗含磨线连接开发板和电脑，

BOOT0选择为1，BOOT1选择为0，

接老此上开发板电源，SW1切换到ON打开电源开关。

3、 从开始程序菜单打开Flash Loader Demo程序，所有程序->STMicroelectronics->Flash

Loader Demonstrator->Flash Loader Demo
