The I2C bus was designed by Philips in the early '80s to allow easy communication between components which reside on the same circuit board. Philips Semiconductors migrated to NXP in 2006. The name I2C translates into "Inter IC".

The next tutorial will focus on Timers and Interrupts. Happy Coding! Next post by Enrico Garante: MSP430 Launchpad Tutorial - Part 2 - Interrupts and timers. In this tutorial you will learn how to use an I2C LCD 16x2 display (and 20x4, e.t.c.) with Arduino uno. With I2C module you will be able to connect the LCD with Arduino board with only two cables! The i2c module has a built in potentiometer for contrast a Alternatively I?C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C). Since October 10, 2006, no licensing fees are required to implement the I?C protocol. However, fees are required to obtain I?C slave addresses allocated by NXP. Learn PIC Microcontroller the quick and easy way! The lessons in this tutorial is designed to easily grasp the concept of microcontroller programming. Raspberry Pi SPI and I2C Tutorial; This tutorial will walk you through getting the I2C and SPI interfaces of your Raspberry Pi working. These interfaces aren't enabled by default, and need some extra configuration before you can use them. I2C & SPI Tutorial SPI - Serial Peripheral Interface The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard which opererate in a full duplex mode. i About the Tutorial Arduino is a prototype platform (open-source) based on an easy-to-use hardware and software. It consists of a circuit board, which can be programed (referred to as I2C-bus specification and user manual • Serial, 8-bit oriented, unidirectional data transfers up to 5 Mbit/s in Ultra Fast-mode • On-chip filtering rejects spikes on the bus data line to preserve data integrity.
