感谢 发烧友学院以及广东比派科技 为我和孩子提供此产品 Banana PI Leaf S3开发板。感谢 大佬们的支持指导。

BPI-Leaf-S3是一款板载ESP32-S3芯片的小巧型开发板，支持2.4 GHz Wi-Fi 和低功耗蓝牙 (Bluetooth® LE) 双模无线通信，可直接应用于物联网低功耗项目，其外观如图1所示

处理器简介

以下是ESP32-S3芯片重要功能的描述。

·

**支持****Wi-Fi +

Bluetooth 5 (LE) ** 无线连接 : ESP32-S3 集成 2.4 GHz Wi-Fi (802.11 b/g/n)，支持 40 MHz 带宽；其低功耗蓝牙子系统支持 Bluetooth 5(LE) 和 Bluetooth Mesh，可通过 Coded PHY 与广播扩展实现远距离通信。它还支持 2 Mbps PHY，用于提高传输速度和数据吞吐量。ESP32-S3 的 Wi-Fi 和 Bluetooth LE 射频性能优越，在高温下也能稳定工作。

·

支持 ** AI ** 加速 : ESP32-S3 MCU 增加了用于加速神经网络计算和信号处理等工作的向量指令 (vector instructions)。AI 开发者们通过 ESP-DSP 和 ESP-NN 库使用这些向量指令，可以实现高性能的图像识别、语音唤醒和识别等应用。

·

丰富的 ** IO ** 接口 : ESP32-S3 拥有 45 个可编程 GPIO 以及 SPI、I2S、I2C、PWM、RMT、ADC、UART、SD/MMC 主机控制器和 TWAITM 控制器等常用外设接口。其中的 14 个 GPIO 可被配置为 HMI 交互的电容触摸输入端。此外，ESP32-S3 搭载了超低功耗协处理器 (ULP)，支持多种低功耗模式，广泛适用于各类低功耗应用场景。

完善的安全机制 : ESP32-S3 为物联网设备提供了完善的安全机制和保护措施，防止各类恶意攻击和威胁。它支持基于 AES-XTS 算法的 flash 加密、基于 RSA 算法的安全启动、数字签名和 HMAC。ESP32-S3 还新增了一个“世界控制器 (World Controller)”模块，提供了两个互不干扰的执行环境，实现可信执行环境或权限分离机制。

准备操作系统（win10)

MicroPython运行环境搭建

安装Python环境

Python官网

对于Windows系统来说，最便捷的安装包下载方法就是在官网首页点击如下图所示的图标进行下载。

如果连接Python官网太慢可以在这下

Python 3.10.7

开始安装python-3.10.7-amd64.exe，注意勾选Add Python 3.10 to PATH，这样可以避免后期再进行手动添加路径。

按照安装提示逐步操作即可顺利完成安装。

安装Thonny IDE

以Windows PowerShell的具体操作步骤为例。

右键Windows开始菜单找到运行（或者按快捷win+R）。

通过Python包管理工具pip来安装Thonny IDE。

首先确认pip是否是最新版，使用以下命令升级pip：

pip install -U pip

PS C:\Users\Administrator> pip install -U pip

  DEPRECATION: thonnyapp is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

用Windows搜索即可快速找到Thonny，也可以在开始菜单栏里找到它。

连接开发板至电脑

将开发板通过USB数据线连接至电脑。

正确连接时开发板的电源指示灯会亮起。

我们需要知道开发板是否被电脑识别，并找出连接到了哪一个COM口。

击“此电脑”，右键“属性”，左侧找到打开设备管理器，点开端口。

此时会在列表中新加入一个COM口。

给开发板烧录MicroPython固件

开发板已经预安装MicroPython固件

如果没有从下面地方找 Micropython 固件下载与烧录方法

MicroPython固件

配置Thonny IDE

打开Thonny，选择语言方式，单击let`s go运行

单击运行，点击配置解释器：

将解释器设置为MicroPython(ESP32):

选择开发板的COM口：

REPL启动并输出信息即意味着MicroPython固件烧录成功，可以开始正常使用了。

MicroPython v1.19.1-dirty on 2022-08-17; BPI-Leaf-S3 with ESP32-S3

Type "help()" for more information.

单击视图，勾选文件，即可看到本地文件目录和开发板上的文件目录：

其他视图窗口也可按需设置使用。

在工具选项设置中可以选择个人喜欢的主题风格。

有了开发环境的支持，后面就可以进入正常使用状态了。

在BPI-Leaf-S3开发板上载有一个全彩LED灯珠，该灯珠的引脚同GPIO48相连，通过例程的下载则可产生3基色循环变化效果。

另存为

选择MicroPython设备

将代码保存为main.py

点击Thonny IDE的运行按钮，即可使全彩LED灯珠产生3基色循环变化效果闪烁。

具体例程开发厂家代码可以参考这里

****板正常，达到预期状态。环境搭建并初步测试 结束
