Esp8266 - beginner level Chapter 1

A column is set here to record ESP8266 introduction

Because the chip I currently have is ESP-07S, The connection method is to use a USB Connect the serial port to the chip for basic testing , Later, it will be transplanted to the project for use

ATK_ESP8266 Module support STA/AP/STA+AP Three working modes .
 STA Pattern ： ESP8266 The module connects to the Internet through a router , The mobile phone or computer realizes the control of the device through the Internet
Remote control .
 AP Pattern ： The default mode ATK_ESP8266 Modules as hot spots , Realize the direct communication between mobile phone or computer and module , real
Current LAN Wireless Control .
 STA+AP Pattern ： The coexistence of the two modes , （STA Pattern ） You can connect to the Internet through a router , and
Control the device via the Internet ;（AP Pattern ） Can also be used as wifi hotspot , other wifi The device is connected to the module . this
It can realize the seamless switching between LAN and WAN , Convenient operation .

First determine what mode we want to work ?

Of course, it's a coexistence model

The first is to download firmware

UART Download mode
GPIO0 and GPIO15： Low level
GPIO2： High level

Download the agreement and view ,

There are usually official pc download software , In this case, we can not write how to use mcu Go download the program .

After the software is opened, the corresponding hardware is set to download mode , The upper computer software is opened and set to developer mode
