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 ...

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

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...

We used the Bus Pirate universal serial interface tool to work with the DAC, but the same basic principals apply to any custom implementation. The connections between the Bus pirate and the LTC2631A ...

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.

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 ...

In my last column [LJ, December 2003], we discussed how I2C bus drivers and I2C algorithm drivers work. We also described how to make a tiny dummy I2C bus driver. This month, we discuss how an I2C ...
