How to make a web configuration with ESP8266 [Copy link]

 Preparation Prepare an ESP-F module from Shenzhen Sibo Zhilian Technology Co., Ltd. Or a NODEMCU from Sibo Zhilian Technology When we get the ESP-F module, we can test it according to the following wiring: VCC, EN connect to 3.3v, GPIO15 GND connect to ground, TX, RX of the module connect to the RX, TX, RST pins of the serial port tool for low-level reset, unnecessary IO pins can be left floating, if you want to download the firmware in the module, please pull GPIO0 down (warm reminder: if you buy ESP-01S/M/F1/F2, you only need to connect VCC GND RX TX to work normally). If you buy an ESP-01 module, you only need to connect CH-PD to VCC. Other wiring can be done according to the figure below (IO ports that are not available can be left unconnected). The wiring is as follows: Figure 1.1 Test After completing the wiring according to 1.1, please check the circuit in detail. To confirm that there is no problem, please open the serial port debugging assistant and select the corresponding COM port. The configuration mode is baud rate: 115200, data bit: 8 parity bit: none stop bit: 1 flow control: none. The configuration information is as follows: To confirm that there is no problem, please press the K1 button RST reset button (a low level of about 300m). The print information is as follows: Display ready proves that the startup is normal. Common tool download link: http://pan.baidu.com/s/1geBkYDd Common problems: 1. The button does not respond (1) Please check whether the module power supply is 3.3V/800ma; (2) Please check whether TX and RX are connected in the wrong position; (3) Check whether the port number is selected correctly and whether the port of the serial port debugging assistant is closed. 2. The buttons are all garbled (1) Please confirm the module's baud rate with the module manufacturer; (2) Please check whether the USB to TTL converter that communicates with the module is a compatibility issue. It is recommended to use the USB to TTL converter made of CH340 and CP2102 chips. (3) Please confirm whether there is a problem with the program in the module. Burning program Open ESPFlashDownloadTool_v3.4.1, download tool, select the corresponding chip model Note: The selection information above the picture. Instructions for use 1. Open the serial port debugging assistant to power on the module again and print the information as follows. Note the output information of the serial port: 2. Connect the computer or mobile phone to the module's AP hotspot link ESP's WIFI name. Open the browser and enter 192.168.4.1. Enter the account and password: the account and password are unified as admin. The display interface is as follows: Port setting: client UDP/TCP transparent transmission: server UDP/TCP setting: You can set the module's hotspot directly in the web page, and you can also link to routers and other module program download link: WEB.bin (4 MB, download times: 14) Author: Mirror Flower_d049 Link: https://www.jianshu.com/p/927c0c86260a Source: Jianshu The copyright of Jianshu belongs to the author.
