-# STM32F767 NUCLEO-F767ZI开发板 BSP 说明

-## 简介

-

-本文档为 NUCLEO-F767ZI 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-F767ZI 是st推出的一款基于 ARM Cortex-M7 内核的开发板，最高主频为 216Mhz，该开发板具有丰富的板载资源，可以充分发挥 STM32F767 的芯片性能。

-

-开发板外观如下图所示：

-

-![board](figures/en.high-perf_nucleo-144_mbed.jpg)

-

-该开发板常用 **板载资源** 如下：

-

-- MCU：STM32f767，主频 216MHz，2MB FLASH ，512KB RAM ，16K CACHE

-

-- 常用外设

-  - LED ：3个，LED1 (绿色，PB0),LED2（蓝色，PB7），LED3（红色，PB14）

-## 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)。
