At L-3 Communications, we use PLLs (phase-locked loops) in many of our products to generate precise, stable signals. To program these parts, we must load several control registers with digital words ...

Introduction: Serial to Peripheral Interface (SPI) is a hardware/firmware communications protocol developed by Motorola and later adopted by others in the industry. Microwire of National Semiconductor ...

Electronics are everywhere. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care that there is a ...

Analog-to-Digital Converter (ADC) is used for the conversion of analog signals such as voltage to digital form so that they can be read and processed by a microcontroller or microprocessor. The user ...

The serial peripheral interface (SPI) bus is a synchronous, full-duplex, serial data link commonly used for the short-distance data exchange between a master device, such as a microcontroller unit ...

I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...

We covered SparkFun’s new RGB button pad controller a few weeks ago. This is a full-color clone of the monome interface; a 4×4 grid of buttons with tri-color LEDs underneath. Each LED has 24bits of ...

Electronics is everywhere, especially these days. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care ...
