\"I2C<\/p>\n

 <\/p>\n

In this article, we’ll deep dive into I2<\/sup>C serial communication protocol. What is I2<\/sup>C communication? And how I2<\/sup>C works? And where I2<\/sup>C bus is used? And much more questions will be answered. This article will start by defining the I2<\/sup>C communication basics and show you the I2<\/sup>C bus specifications and standards as published by NXP the originator of I2<\/sup>CTM<\/sup>. Then we’ll discuss specifically the I2<\/sup>C hardware in Microchip PIC microcontrollers, and see how it works and how to configure it. We’ll then develop a simple driver code to test it out. And finally, do a couple of LAB projects to put it all together and get it to work practically.<\/span><\/p>\n

It’s going to be a very long read, so stick around and let’s get started!<\/span><\/p>\n
