-- 进阶使用方法
+STM32F412xE/G devices belong to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing even more power consumption saving during data batching.
+STM32F412xE/G devices incorporate high-speed embedded memories (up to 1 Mbyte of Flash memory, 256 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
+All devices offer one 12-bit ADC, a low-power RTC, twelve general-purpose 16-bit timers, two PWM timers for motor control and two general-purpose 32-bit timers.
+They also feature standard and advanced communication interfaces:
+In addition, STM32F412xE/G devices embed advanced peripherals:
+STM32F412xE/G devices are offered in 7 packages ranging from 48 to 144 pins. The set of available peripherals depends on the selected package.
+The STM32F412xE/G operates in the -40 to +125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
+These features make the STM32F412xE/G microcontrollers suitable for a wide range of applications.

-
-### 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 Micro-B 线连接开发板和 PC 供电，黄色 LED LD6 (PWR) 和 LD4 (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 板载ST-LINK 仿真器下载程序，在通过 Micro USB线 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，在JP5跳帽连接时，观察开发板上LD1的运行效果，黄色LED会周期性闪烁。

+## 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 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，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
+ / | \     4.0.0 build Jan  9 2019
+ 2006 - 2018 Copyright by rt-thread team
+msh >
+```
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口3 的功能，如果需使用 Ethernet 等更多高级功能，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)。
