Read temperature and humidity data through IIC protocol

1. Definition of I2C “I2C” stands for “Inter-Integrated Circuit” and is a commonly used serial communication protocol used to transfer data between different integrated circuits. When using the I2C protocol, there are usually two main implementations, namely “software I2C” and “hardware I2C”. 1. Software I2C: Software I2C is an implementation that simulates the I2C protocol […]
