+# STM32G431-Nucleo BSP Introduction
+
+[中文](README_zh.md) 
+
+## MCU: STM32G474RB @170MHz, 512KB FLASH,  128KB RAM
+
+The STM32G474xB/xC/xE devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security.
+These devices embed high-speed memories (up to 512 Kbytes of Flash memory, and 128 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad-SPI Flash memory interface, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
+The devices also embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, securable memory area and proprietary code readout protection.
+The devices embed peripherals allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions).
+They offer five fast 12-bit ADCs (4 Msps), seven comparators, six operational amplifiers, seven DAC channels (3 external and 4 internal), an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timers, three 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer, and high resolution timer with 184 ps resolution.
+They also feature standard and advanced communication interfaces such as:
+\- Four I2Cs
+\- Four SPIs multiplexed with two half duplex I2Ss
+\- Three USARTs, two UARTs and one low-power UART.
+\- Three FDCANs
+\- One SAI
+\- USB device
+\- UCPD
+The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.
+Some independent power supplies are supported including an analog independent supply input for ADC, DAC, OPAMPs and comparators. A VBAT input allows backup of the RTC and the registers.
+The STM32G474xB/xC/xE family offers 9 packages from 48-pin to 128-pin.

+## 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，通过数据线对开发板供电,下载,调试。
+
+#### 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，黄色的 LD2 以 500MS 周期闪烁。
+
+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
+ / | \     4.0.2 build Oct  5 2019
+ 2006 - 2019 Copyright by rt-thread team
+msh >
+```
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 LPUART1 的功能，如果需使用更多高级功能，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)。
+
+## 注意事项
+
+- 默认终端输出设备是 LPUART1
