# STM32G431-Nucleo BSP Introduction

## 简介
|
||||
[中文](README_zh.md)
|
||||
|
||||
本文档为 NUCLEO-G431RB 开发板的 BSP (板级支持包) 说明。
|
||||
## MCU: STM32G431RB @170MHz, 128KB FLASH, 32KB RAM
|
||||
|
||||
主要内容如下：
|
||||
The STM32G431x6/x8/xB devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz.
|
||||
|
||||

|
||||
- BSP 快速上手
|
||||
- 进阶使用方法
|
||||
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 (128 Kbytes of Flash memory, and 32 Kbytes of SRAM), 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 two fast 12-bit ADCs (5 Msps), four comparators, three operational amplifiers, four DAC channels (2 external and 2 internal), an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer.
|
||||
They also feature standard and advanced communication interfaces such as:
|
||||
\- Three I2Cs
|
||||
\- Three SPIs multiplexed with two half duplex I2Ss
|
||||
\- Three USARTs, one UART and one low-power UART.
|
||||
\- One FDCAN
|
||||
\- 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 STM32G431x6/x8/xB family offers 9 packages from 32-pin to 100-pin.
|
||||
|
||||
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。

||||
|
||||
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。
