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

Several of the Mid-Range Enhanced Core PIC16 microcontroller devices have a Master Synchronous Serial Port (MSSP). The MSSP module can be used to implement either I2CTM or SPI communications protocol.

The goal of this application note is to present an practical example of communication using the I2C peripheral of the ST7. It shows a basic single master communication between a ST7 microcontroller ...

It’s not much of a stretch to assume that the majority of Hackaday readers are at least familiar with I2C. In fact, there’s an excellent chance that anyone who’s ever done more with an Arduino than ...

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a ...

It’s probably fair to say that anyone reading these words understands conceptually how physically connected devices communicate with each other. In the most basic configuration, one wire establishes a ...
