![]() Ultra Fast-Mode (UFm), with a bit rate of up to 5 Mbit/s.High-speed Mode (Hs-mode), with a bit rate up to 3.4 Mbit/s.Fast-Mode Plus (Fm+), with a bit rate up to 1 Mbit/s.Fast-Mode (Fm), with a bit rate up to 400 kbit/s.Standard-Mode (Sm), with a bit rate up to 100 kbit/s.Standard-mode, Fast-mode (Fm), Fast-mode Plus (Fm+), and High-speed mode (Hs-mode) Over time there have been several additions to the specification so that there are now five operating speed categories. Originally, the I2C-bus was limited to 100 kbit/s operations. Just as external EEPROMs, Digital Temperature Sensors, LCD Controllers, OLED Display, RTC, and much more. 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.

Arduino IDE For ESP32 (Setup Guide) Hardware Components. ![]() 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. Arduino Basic: How to use the Arduino I2C Scanner?
