+# NUCLEO-F072RB 开发板 BSP 说明
+
+## 简介
+
+本文档为刘恒为 NUCLEO-F072RB 开发板的 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
+
+NUCLEO-F072RB 是 ST 官方推出的开发板，搭载 STM32F072RBT6 芯片，基于 ARM Cortex-M0 内核，最高主频 48 MHz，具有丰富的板载资源，可以充分发挥 STM32F072RBT6 的芯片性能。
+
+开发板外观如下图所示：
+
+![board](figures/board.jpg)
+
+NUCLEO-F072RB 开发板常用 **板载资源** 如下：
+
+- MCU：STM32F072RBT6，主频 48MHz，128KB FLASH ，16KB RAM
+- 常用外设
+  - LED：3 个，USB communication (LD1), user LED (LD2), power LED (LD3) 。
+  - 按键：2 个，USER and RESET 。
+- 常用接口：USB 转串口、Arduino Uno 和 ST morpho 两类扩展接口
+- 调试接口：板载 ST-LINK/V2-1 调试器。
+
+更多相关信息资料见 ST 官网详情页：[NUCLEO_F072RB_STM32Nucleo-64开发板]https://www.stmcu.com.cn/Designresource/design_resource_detail?file_name=NUCLEO_F072RB_STM32Nucleo-64%E5%BC%80%E5%8F%91%E6%9D%BF&lang=EN&ver=
+
+## 外设支持
+
+本 BSP 目前对外设的支持情况如下：
+
+| **片上外设**   | **支持情况** |               **备注**                 |
+| :------------ | :----------: | :-----------------------------------: |
+| GPIO          |     支持     | PA0, PA1... PH1 ---> PIN: 0, 1...63    |
+| UART          |     支持     |              UART2                     |
+| LED           |     支持     |              LED2                      |
+
+## 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 Type-A to Mini-B 线连接开发板和 PC 供电，红色 LED LD3 (PWR) 和 LD1 (COM) 会点亮。
+
+#### 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 下载程序，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，系统会自动运行，观察开发板上 LED 的运行效果，红色 LD3 和 LD1 常亮、绿色 LD2 会周期性闪烁。
+
+USB 虚拟 COM 端口默认连接串口 2，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:

+msh >
+
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口 2 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)。

+  * @brief   CMSIS Cortex-M0 Device Peripheral Access Layer System Source File.
+  *
+  * 1. This file provides two functions and one global variable to be called from
+  *    user application:
+  *      - SystemInit(): This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f0xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. This file configures the system clock as follows:
