+# STM32F723E-disco 开发板 BSP 说明
+
+## 简介
+
+本文档是 STM32F723E-disco 开发板提供的 BSP (板级支持包) 说明。
+
+主要内容如下：
+
+- 开发板资源介绍
+- BSP 快速上手
+- 进阶使用方法
+
+通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。在进阶使用指南章节，将会介绍更多高级功能，帮助开发者利用 RT-Thread 驱动更多板载资源。
+
+## 开发板介绍
+
+STM32F723E-disco 是 ST 推出的一款基于 ARM Cortex-M7 内核的开发板，最高主频为 216Mhz，该开发板具有丰富的板载资源，可以充分发挥 STM32F723 的芯片性能。
+
+开发板外观如下图所示：
+
+![board](figures/board.png)
+
+该开发板常用 **板载资源** 如下：
+
+- MCU：STM32f723，主频 216MHz，512MB FLASH ，256KB RAM
+- 常用外设
+  - 按键：2个，Reset 和 User。
+- 调试接口，ST-LINK/V2-1
+
+开发板更多详细信息请参考官网 [STM32F723E-disco 开发板介绍](https://www.st.com/en/evaluation-tools/32f723ediscovery.html)。
+
+主芯片更多详细信息请参考官网 [STM32f723 芯片资料](https://www.st.com/zh/microcontrollers-microprocessors/stm32f723ie.html)。
+
+## 外设支持
+
+本 BSP 目前对外设的支持情况如下：
+
+| **板载外设**      | **支持情况** | **备注**                              |
+| :----------------- | :----------: | :------------------------------------- |
+| USB 转串口   |     支持     |              UART6                  |
+
+
+## 使用说明
+
+使用说明分为如下两个章节：
+
+- 快速上手
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+- 进阶使用
+
+    本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
+
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 工程默认配置使用 st-link 仿真器下载程序，在通过 st-link 连接开发板的基础上，点击下载按钮即可下载程序到开发板
+
+#### 运行结果
+
+下载程序成功之后，LED 闪烁。
+
+连接开发板对应串口到 PC ，在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     5.0.0 build Mar  1 2023 16:20:11
+ 2006 - 2022 Copyright by RT-Thread team
+msh >
+```
+
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口6 的功能，更多高级功能，需要利用 ENV 工具对 BSP 进行配置，步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+
+2. 输入 `menuconfig` 命令配置工程，配置好之后保存退出。
+
+3. 输入 `pkgs --update` 命令更新软件包。
+
+4. 输入 `scons --target=mdk4/mdk5/iar` 命令重新生成工程。
+
+本章节更多详细的介绍请参考 [STM32 系列 BSP 外设驱动使用教程](../docs/STM32系列BSP外设驱动使用教程.md)。
