+## FAQ
+
+###  GCC环境如何调试使用
+
+第一步，需要配置arm-none-eabi-gcc路径到系統环境变量中去或者在rtconfig.py中EXEC_PATH  修改路径
+
+第二步，添加openocd的路径，如果你安装了eclipse，添加以下路径到系统环境变量中
+
+`C:\Maxim\Toolchain\bin`
+
+完成这两部就可以用vscode打开bsp目录了。
+
+快捷键ctrl+shift+b可以执行scons编译命令
+
+快捷键F5可以进入调试命令
+
+如果需要调试之前执行build命令，在luanch.json里面打开注释
+
+```
+            //"preLaunchTask": "build"
+```

-# STM32F103C8T6最小系统板 BSP 说明
-
-## 简介
-
-本文档为 STM32F103C8T6最小系统板 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
-
-STM32F103C8T6最小系统，采用SWD调试接口，可以用3个接口就能完成调试下载的任务，采用了官方建议的负载RTC晶振方案，小体积高频率的STM32实验板
-
-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：STM32F103C8T6，主频 72MHz，64KB FLASH ，20KB RAM
- 外部 RAM：无
- 外部 FLASH：无
- 常用外设
-  - LED：1个，DS0（黄色，PC13）
- 常用接口：无
- 调试接口，SWD调试接口
-
-开发板更多详细信息请参考[STM32F103C8T6最小系统板介绍]
-
-## 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**                              |
-| :----------------- | :----------: | :------------------------------------- |
-| 	黄色LED		    |     支持      |       PC13                          |
-| **片上外设**      | **支持情况** | **备注**                              |
-| GPIO              |     支持     | PA0, PA1... PC15 ---> PIN: 0, 1...47 |
-| UART              |     支持     | UART1                                |
-| **扩展模块**      | **支持情况** | **备注**                              |
-|     		       |              |                                      |
-
-## 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 J-Link 仿真器下载程序，在通过 J-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，系统会自动运行，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
- / | \     4.0.1 build Mar 10 2019
- 2006 - 2019 Copyright by rt-thread team
-msh >
-```
-### 进阶使用
-
-此 BSP 默认只开启了 GPIO 和 串口1 的功能，如果需使用 ADC、PWM等更多高级功能，再用 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)。
-
-## 注意事项
-
- 只能用USB转TTL连接PC机 ;

-  * @file    system_stm32f1xx.c
-  * @author  MCD Application Team
-  * @version V4.2.0
-  * @date    31-March-2017
-  * @brief   CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
-  * 
-  * 1.  This file provides two functions and one global variable to be called from 
-  *     user application:
-  *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
-  *                      factors, AHB/APBx prescalers and Flash settings). 
-  *                      This function is called at startup just after reset and 
-  *                      before branch to main program. This call is made inside
-  *                      the "startup_stm32f1xx_xx.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_stm32f1xx_xx.s" file, to
-  *    configure the system clock before to branch to main program.
-  *
-  * 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depending on
-  *    the product used), refer to "HSE_VALUE". 
-  *    When HSE is used as system clock source, directly or through PLL, and you
-  *    are using different crystal you have to adapt the HSE value to your own
-  *    configuration.

-  *

-  *         (*) HSI_VALUE is a constant defined in stm32f1xx.h file (default value
