It’s widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication.

The I 2C is a multi-master, multi-slave, synchronous, bidirectional, half-duplex serial communication bus. I 2C (i-square-c) is an acronym for “Inter-Integrated-Circuit” which was originally created by Philips Semiconductors (now NXP) back in 1982.

Requirements For This Tutorial Prior Knowledge Without further ado, let’s get right into it! It’s something similar to the commonly known Arduino Wire library as we’ll see. Then, we’ll move to the Arduino Core libraries that implement drivers for the ESP32 I2C peripheral and how to use its API functions. ESP8266 UDP Send & Receive Example (Step by Step Arduino Guide)
