#### 硬件架构

##### 概要

![输入图片说明](screenshot-arduino-esp8266.readthedocs.io-2024.09.29-19_36_41.png)

部件 一块esp-12-f 和 usb烧写板，三线连接GND ，RXD ，TXD 

买的烧写板的TXD和RXD 相反。

#### 软件架构

##### 1.开发环境搭建

 **选择windows 10 下编译** 

> （不用arduino本身的开发管理器），因为不容易下载

按照下面步骤，没用 git，直接去下载*.zip. 使用arduino-3.1.2.zip 
```
Instructions - Windows 10

First, make sure you don’t already have an ESP8266 core version installed using the Board Manager (see above). If you do, uninstall it from the Board Manager before proceeding. It is also advisable to erase the Arduino15 contents.

Install git for Windows (if not already; see https://git-scm.com/download/win)

Open a command prompt (cmd) and go to Arduino default directory. This is typically the sketchbook directory (usually C:\users\{username}\Documents\Arduino where the environment variable %USERPROFILE% usually contains C:\users\{username})

Clone this repository into hardware/esp8266com/esp8266 directory.

cd %USERPROFILE%\Documents\Arduino\
if not exist hardware mkdir hardware
cd hardware
if not exist esp8266com mkdir esp8266com
cd esp8266com
git clone https://github.com/esp8266/Arduino.git esp8266
You should end up with the following directory structure in

C:\Users\{your username}\Documents\

Arduino
|
--- libraries
--- hardware
    |
    --- esp8266com
        |
        --- esp8266
            |
            --- bootloaders
            --- cores
            --- doc
            --- libraries
            --- package
            --- tests
            --- tools
            --- variants
            --- platform.txt
            --- programmers.txt
            --- README.md
            --- boards.txt
            --- LICENSE
Initialize the submodules

cd %USERPROFILE%\Documents\Arduino\hardware\esp8266com\esp8266
git submodule update --init
If error messages about missing files related to SoftwareSerial are encountered during the build process, it should be because this step was missed and is required.

Download binary tools

cd tools
python3 get.py
Restart Arduino

If using the Arduino IDE for Visual Studio (https://www.visualmicro.com/), be sure to click Tools - Visual Micro - Rescan Toolchains and Libraries

When later updating your local library, goto the esp8266 directory and do a git pull

cd %USERPROFILE%\Documents\Arduino\hardware\esp8266com\esp8266
git status
git pull
Note that you could, in theory install in C:\Program Files (x86)\Arduino\hardware however this has security implications, not to mention the directory often gets blown away when re-installing Arduino IDE. It does have the benefit (or drawback, depending on your perspective) - of being available to all users on your PC that use Arduino.

```

说明一下，

（a） esp8266 的源码放在arduino中，arduino中工具栏-开发板-esp8266 的选项 

（b） python3 get.py 下载tooschain 和 python3.7 

（c） 没用git submodule update --init ，直接下载里面的包，放到指定目录


##### 2.编译和上传


重新打开arduino 

工具-esp8266（3.1.2）- ESPino

编译

##### 3.样例程序

（1） GPIO 读写 和 串口读写 

------

#### 问题

##### 1.关于开发环境搭建的问题


###### (a). python3 get.py 下载太慢

下载地址： https://github.com/earlephilhower/esp-quick-toolchain/releases/

下载合适版本查看下面

C:\Arduino\hardware\esp8266com\esp8266\package\package_esp8266com_index.template.json

根据上面的json 

下载四个文件

> ESP8266 Quick Toolchain for 3.1.0-gcc10.3 下：

```
python3-3.7.2.post1-embed-win32v2a (2).zip

x86_64-w64-mingw32.esptool-f80ae31.220621.zip     19.3 KB   Jun 22, 2022

x86_64-w64-mingw32.mklittlefs-30b7fc1.220621.zip  339 KB    Jun 22, 2022

```

###### (b).  git submodle init 问题直接下载*.zip

太慢   手动下载

最好下载3.0,存放指定的文件夹中

##### 2. 关于编译和烧写的问题

烧写中上传问题

pyserial or esptool directories not found next to this upload.py tool

更换esptool
