WIFI weather clock design based on STM32

This project is for the Radio Association Desktop Clock Competition of the School of Physics and Electronic Engineering of Chongqing Normal University.
       WIFI weather clock design based on STM32, using STM32F103ZET6 (Punctual Atomic Elite Board) microcontroller as the main control, which can obtain date, time, week, temperature, wind direction, wind speed and weather information through ESP8266, using a 0.56-inch blue four-digit total The digital tube (with decimal point) displays the time. The driver chip of the digital tube is TM1637. It also uses a 2.8-inch TFTLCD touch screen. The screen can display the name of the current area, the current time, the weather conditions of the current area and the next two days. weather conditions of the day. There are buttons on the back of the circuit board, and you can use the switch to reset, adjust the display brightness of the digital tube, redistribute the network and other functions. This design also has a voice broadcast system, which can set alarm clock and hourly time. More functions are still under development. The source code comes from CSDN user @CodeDog_wang. I have added, modified and optimized some of the code.
