# NUCLEO-G431RB 开发板 BSP 说明
## 简介
本文档为 NUCLEO-G431RB 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-G431RB 是 ST 公司推出的一款针对 STM32G4 系列设计的 Cortex-M4 Nucleo-64 开发板，支持 mbed，兼容 Arduino、还带有 ST Morpho 扩展接口，可连接微控制器的所有周边外设。
开发板外观如下图所示：
![board](figures/board.jpg)
该开发板常用 **板载资源** 如下：
- MCU：STM32G431RB，主频 170MHz，128KB FLASH ，22KB RAM
- 常用外设
- LED：1个，LD2（黄色，PA5）
- 常用接口：USB 转串口
- 调试接口，标准 ST-LINK/SWD
开发板更多详细信息请参考【NUCLEO-G431RB】 [开发板介绍](https://www.st.com/zh/evaluation-tools/nucleo-g431rb.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 | |
| **片上外设** | **支持情况** | **备注** |
| GPIO | 支持 | |
| UART | 支持 | LPUART1 USART1/3 UART4 |
## 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
