Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95. The latest breakout board ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

I2C is a two-wire communication protocol known for its simplicity. Despite this reputation, I2C does have its challenges: a limited number of bits for a unique address can create address conflicts, or ...

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...

I had one of those why-didn’t-I-think-of-it moments this week, reading this article about multiplexing I2C on the ESP32 microcontroller. The idea is so good, and so simple, that it’s almost silly that ...

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 ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...
