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 ...

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 ...
