Interface Description

Burning mouth:

The GND, RX, TX, and 5V of ESP8266 are respectively connected to the GND, TX, and RX of the external TTL serial module,

5V， When downloading, IO0 needs to be connected to GND. After the download is complete, disconnect the connection between IO0 and GND;

Relay output terminal:

NC: normally closed end, short circuited to COM before relay closing, suspended after closing;

COM: Public end;

NO: Constant start, the relay is suspended before closing and short circuited to COM after closing.

Introduction to GPIO Export Ports

ARDUINO development environment setup

ESP8266 supports development tools such as ECLIPSE/ARDUINOIDE, but using ARDUINO requires relative support

Simple, here is the method for setting up the ARDUINO development environment:

1. Install ARDUINO IDE 1.8.9 or the latest version;

2. Open ARDUINO IDE, click on "File" in the menu bar - "Preferences", enter "Preferences", and then go to the "Additional Development Board Manager" website

Click on 'Add URL' in the 'Address' section:

http://arduino.esp8266.com/stable/package_esp8266com_index.json ,

3. Click on "Tools" ->"Development Board" ->"Development Board Manager" in the menu bar, and then search for "ESP8266" to install ARDUINO

ESP8266 support package 2.5.2 or the latest version

Note: Due to the download URL being from overseas, the access speed is relatively slow, and there may be download errors. Please wait for the network to improve

Just try a few more times in this situation.

Program Download

1. Use jumper caps/DuPont wires to connect the IO0 and GND pins, and prepare a TTL serial port module (such as FT232) to plug into the computer

USB， The connection method between the serial module and the development board is as follows:

2. Click on the tools in the menu bar - Development Board, and select ESPINO (ESP-12 MODULE) as the development board

3. Open the program you want to download, click on "Tools" in the menu bar, select "Port" and choose the correct port number

4. After clicking "Upload", the program will automatically compile and download to the development board, as follows:

5. Finally, disconnect the connection between IO0 and GND, and the development board can be powered on again or press the reset button to run the program.
