We learn to use the I2C protocol.

ALMOST ALL THE PROTOCOL I2C

Introduction

I think now will be a few people not to have heard at least once in the I2C protocol. Suppose further that all will know that this system allows the transfer of data between two or more electronic devices in a serial fashion, with just two wires and in both directions. This means that within a more or less complex circuitry, two or more devices can communicate with each other, moving large amounts of data with a complexity ardware greatly simplified. Generally in an electronic circuit thus conceived there is a "master" and the "slave". The first and always a microprocessor or microcontroller that has devolved the task of organizing and directing the data traffic or directed, or by the "slave". [Read more →]
