STM32开发板使用说明1、开发板使用到的软件及安装说明在开始学习开发板之前需要安装的软件有：1、KEIL3.80A，2、PL-2303HX驱动，3、串口调试助手，4、下载器MCUISP。
这些软件在课件文件下面的软件文件里。
具体安装步骤如下：1．KEIL3.80A的安装，打开路径：课件\软件\KEIL3.80A\MDK3.80A安装手册，根据上面的步骤安装软件。
2．PL-2303HX驱动的安装，打开路径：课件\软件\PL-2303HX新版驱动，可根据使用电脑的操作系统来选择安装的软件，如选择安装XP驱动，可打开XP驱动，根据里面的安装说明来安装软件。
一般只要运行PL-2303 Driver Installer。
exe就可以了。
3．串口调试助手的安装，打开路径：课件\软件\串口调试助手，点击sscom33。
exe即可，也可以创建快捷方式在桌面。
4．下载器MCUISP的安装，打开路径：课件\软件\下载器MCUISP，点击mcuisp。
exe 即可，也可以创建快捷方式在桌面。
2、开发环境介绍及使用说明首先是我们之前安装的keil3.80a。
再点击Project->New uVision Project如下图所示：弹出create new project 对话框，新建一个文件夹TEST，然后把工程名字设为test。
点击保存。
弹出选择器件的对话框，因为我们的开发板使用的是STM32F103RBT6 ，所以在这里我们选择STMicroelectronics 下面的STM32F103RB( 如果使用的是其他系列的芯片，选择相应的型号就可以了)。
如下图所示:点击OK，MDK会弹出一个对话框，问你是否加载启动代码到当前工程下面，这里我们选择是。
启动代码是一段和硬件相关的汇编代码。
是必不可少的!在上面点击了是以后，MDK 就把启动代码STM32F10x。
s 加入到了我们的工程下面。
如下图所示:到这里，我们就可以开始编写自己的代码了。

STM32的几种烧写方法STM32是意法半导体（STMicroelectronics）推出的一系列32位ARM Cortex-M微控制器。
在开发STM32项目时，常常需要通过烧写程序将代码加载到芯片中。
以下是几种常见的STM32烧写方法。
1. ST-Link/V2烧写器ST-Link/V2是STM32系列芯片的官方烧写器。
它是通过USB接口与开发主机连接，并通过调试线与目标芯片连接。
ST-Link/V2支持多种烧写方式，如JTAG、SWD和SWIM。
它可以与STM32编程工具（如ST-Link Utility和STM32CubeProg）结合使用，实现快速、可靠的编程。
2.UART烧写一些STM32系列芯片（如STM32F10x系列）集成了UART引导加载程序（Bootloader），可以通过串口通信进行烧写。
首先，需要将芯片的BOOT0引脚设置为高电平，然后通过串口线将开发主机与芯片连接。
最后，在开发主机上运行特定的烧写工具（如ST Flash Loader Demonstrator），上传并烧写程序到芯片中。
BDFU烧写USB Device Firmware Upgrade（DFU）是一种用于通过USB接口更新固件的标准协议。
STM32系列芯片中的USB DFU引导加载程序可以使设备进入DFU模式，并使用特定的DFU烧写工具（如DfuSe、dfu-util）通过USB接口加载新的固件。
4. IAP烧写（In-Application Programming）IAP是一种在应用程序运行时更新固件的方法。
通过使用IAP库函数，应用程序可以擦除、编程和读取闪存中的数据。
具体实现方式是将新的固件数据传输到目标芯片的特定存储区域，然后由应用程序将固件写入闪存。
5.SD卡烧写一些STM32系列芯片（如STM32F7系列）支持通过SD卡加载程序。
在SD卡上存储已编译的二进制文件，然后将SD卡插入与芯片相连的卡槽，在芯片上电时，引导加载程序将自动读取SD卡上的固件并烧写到存储器中。

STM32F407VET6基于FreeRTOS实时操作系统和LAN8720⽹卡移植LwIP协议栈本次实验是在STM32F407VET6单⽚机上实现FreeRTOS实时操作系统加LwIP协议栈驱动LAN8720⽹卡，板⼦是购买的最⼩系统开发板，⽹卡是购买的LAN8720模块。
使⽤的LwIP内核版本为 lwip-1.4.1，FreeRTOS内核版本为 FreeRTOSv10.2.1。
使⽤上⼀篇博客中移植好的FreeRTOS⼯程。
1、STM32F407VET6单⽚机引脚与LAN8720⽹卡的物理连接如下： a、ETH_RMII_REF_CLK-------> PA1--------->nINT/RETCLK b、ETH_MDIO --------------------> PA2--------->MDIO c、ETH_RMII_CRS_DV --------> PA7--------->CRS d、ETH_RMII_TX_EN ----------> PB11------->TX_EN e、ETH_RMII_TXD0 ------------> PB12------->TX0 f、ETH_RMII_TXD1 -------------> PB13------->TX1 g、ETH_RESET-------------------> PC0-------->NC h、ETH_MDC ---------------------> PC1-------->MDC i、ETH_RMII_RXD0 -------------> PC4-------->RX0 j、ETH_RMII_RXD1 -------------> PC5-------->RX1 注：在⽹卡模块上RESET引脚为NC，未连接，但在实际项⽬中把RESET引脚连接起来使⽤效果更好，LAN8720⽹卡的电源建议加⼀个电源控制，如：三极管或MOS管，在复位前先断⼀下电源，再复位，因为实际中我遇到过软复位不成功的情况。
