This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

In this paper, the authors proposed on I2c protocol following master controller. This controller is connected to a microprocessor or computer and reads 8 bit instructions following I2C protocol. The ...

Inter integrated circuits (I2C) is a multi-master, low-bandwidth, short distance, serial communication protocol. Because of its simplicity and flexibility, I2C and its derivatives are widely employed ...

An Inter-IC bus is often used to communicate across circuit-board distances. Here’s a primer on the protocol. At the low end of the spectrum of communication options for “inside the box” communication ...

Delivers the flexible, multiple-peripherals simplicity of I2C and the faster, lower-latency communication of SPI in a single, efficient, easier-to-use IP core Woodcliff Lake, New Jersey — September 5, ...

The Power Management Bus (PMBus) protocol, a simple and powerful open industry specification, is a step towards unifying communication standards for digital power-management systems and power ...

The digital compensation posts covered all the control aspects of building a switch mode power supply, but did not cover external communication and control. This post will demonstrate how to write ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state potentiometer.
