About this course

"Why am I not receiving an acknowledge from my I2C device? Help!"  "I can't write to my I2C Serial EEPROM and I always read 0xFF. What am I doing wrong?" These are some of the questions we receive from customers working with the I2C protocol, and this class will help to answer these questions and many more. We will start with an introduction to  I2C covering key concepts and signals, continue with configuring PIC® Microcontrollers as an I2C primary or secondary device, and end with a demo showing common I2C communications failures and how to troubleshoot them. This class is recommended for anyone already using, planning to use or just wants to learn more about the I2C protocol.
