 # WiFiLightController
 
+---
+
 基于NodeMcu开发的ESP8266物联网LED灯控制设备，接入SSD1306作为配网以及服务显示功能，后续会增加更多功能
+
+## 1.准备工作🧐
+
+#### 1.1设备清单
+
+`数据线等烧录用不在此列`
+
+| 设备名称        | 数量     | 设备型号                  |
+| ----------- | ------ | --------------------- |
+| ESP8266     | 1      | ESP-12F，其他ESP8266可用型号 |
+| led灯珠       | 4-5个   | 3v3最低耐压               |
+| 电线          | 12-16条 | 常用杜邦线或者其他相似参数         |
+| I2C协议OLED屏幕 | 1      | SSD1306_12864_noname  |
+| USB供电（可选）   | 1      | 3.3v引脚供电&5VUSB供电      |
+
+#### 1.2固件烧录
+
+先从该连接，下载 Flash下载工具(flash_download_tool_3.9.5_0.zip)，如果有新版本可能名称会有所不同。
+
+  [工具 | 乐鑫科技 ](https://www.espressif.com.cn/zh-hans/support/download/other-tools)
+
+下载完之后，将工程下的flash_download_tool_3.9.5.exe打开
+![](DocRes\1_1.jpg)
+
+选择ESP8266
+
+![](DocRes\1_2.jpg)
+
+进入如下界面，点击第一项，选择工程下 Firmware里对应的固件文件，由于程序使用的固件版本为float，但未曾写过使用float类型的程序。int没有测试过，保险起见可以选择float版本，右边填0。选择如下所示，串口检测到后点击对应的串口进行烧录即可。
+
+![](DocRes/1_0.jpg)
+
+烧录的波特率默认为115200，运行以及开发用的波特率同理。
+
+#### 1.3程序烧录
+
+首先去github上下载ESPlorer，右侧release可以下载最新的发布版本，可能需要翻墙。
+
+[ESPlorer](https://github.com/4refr0nt/ESPlorer)
+
+下载完成后运行ESPlorer.bat，即可打开该开发工具，然后打开工程的所有lua文件并保存到ESP8266中。目前还处于手动配置网络的阶段，后续会继续优化该配网功能。
+
+## 2.接线说明🔌
+
+NodeMCU开发板引脚图
+
+![](DocRes/NodeMcu_Pinout.webp)
+
+#### 2.1GPIO-LED接线说明
+
+GPIO控制D0-D4，一共五路GPIO供电开关。
+
+| 接线方式 | LED引脚 | ESP8266引脚 |
+| ---- | ----- | --------- |
+| 直连   | 负极    | GND       |
+| 直连   | 正极    | D0        |
+| 直连   | 正极    | D1        |
+| 直连   | 正极    | D2        |
+| 直连   | 正极    | D3        |
+| 直连   | 正极    | D4        |
+
+#### 2.2SSD1306-12864-I2C接线说明
+
+oled显示屏用于显示配网参数以及连接状态，指示灯状态等信息，方便更快找到设备故障原因。
+
+| 接线方式 | SSD1306-12864-I2C引脚 | ESP8266引脚 |
+| ---- | ------------------- | --------- |
+| 直连   | GND                 | GND       |
+| 直连   | VCC                 | 3v3       |
+| 直连   | SCL                 | D6        |
+| 直连   | SDA                 | D5        |
+
+`如有其他设备需要接线后续补充`
