I2C, also written as I 2 C, and pronounced I-squared-C, is a method for communicating between devices such as sensors, displays and other peripherals and a microcontroller like the Photon or Electron.

In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has ...

Comparing I2C (Inter Integrated Circuits) in STM32F103C8 Blue Pill board with Arduino Uno, then we will see that Arduino has ATMEGA328 microcontroller in it, and STM32F103C8 has ARM Cortex- M3 in it.

This document/repository is intended to act as a skeleton & lesson for creating simple userspace I2C device drivers in Linux. While some of the information below will be specific to the OPT4048, much ...
