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 ...

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 ...

I2C has a seven-bit address space, and you’re thinking “when do I ever need more than 127 devices on a pair of wires?” So you order up some parts only to find that they have one, two, or three ...

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, ...

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 ...
