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 ...

You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many others, all are a ...

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...

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 ...

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 ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

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 ...
