If you’re reading these pages, odds are good that you’ve worked with I²C devices before. You might even be the proud owner of a couple dozen sensors pre-loaded on breakout boards, ready for ...

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 ...

In the world of slower communications, the most popular protocols by far are I²C (for ‘Inter-Integrated Circuit’ protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well suited ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

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 ...

The I2C bus is a set of hardware and software rules that allows communication between multiple devices over a shared, two-wire interface. In operation the bus uses one line (SDA) for data and the ...
