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 ...

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 ...

In the June and August 2003 issues of Linux Journal, my column covered the Linux kernel driver model, and the I2C subsystem was used as an example. This month, we discuss what the I2C subsystem does ...

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, ...

We connected the DS1807 to the Bus Pirate universal serial interface tool as shown in the table, the same basic principals apply to any custom configuration. We used the Bus Pirate’s 5volt power ...

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, ...

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 ...
