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 ...

A few weeks back, we talked about the no-nos of running I²C over long wires. For prototyping? Yes! But for a bulletproof production environment, this practice just won’t make the cut. This month I ...

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 ...
