[Tuya Smart] Thermohygrometer based on Tuya Smart

Overview

This project is designed based on the WB3S module of Tuya Smart. The main control chip is STM32L071, and the USART2 of the MCU is used to communicate with the Tuya module. The indoor temperature and humidity meter in this design uses the high-precision digital temperature and humidity sensor SHT30 and uses the MINI-USB port for power supply. After the board is powered on, each hardware is initialized. When the WB3S module is successfully configured, the LED light on the right side is always on. The MCU transmits temperature and humidity data to the WB3S module and USART1 port.

I2C Library Functions
Dear experts, I use STM32F103VBT and 24C08 to communicate via I2C, using the library (V2.03) function to write data first and then read. During the reading process, SR1 at EV6 becomes 0x0044, while th
