This application note describes the operation of a general- purpose, microcontroller-based Serial Port Interface (SPI) boot circuit. This is a low cost solution for users who need to modify some 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 ...

Local Interconnect Network (LIN) automotive bus systems are mainly placed in the body domain and we experience a constantly increasing number of nodes in the car. This article introduces the concept ...

As many as half of all embedded designs have an FPGA next to a microcontroller. The FPGA can be used to implement anything from glue logic, to custom IP, to accelerators for computationally intensive ...

Hack a Day’s very own (and very prolific contributor) [Mike Szczys] put up a great tutorial on how to drive shift registers with an SPI interface. [Mike]’s earlier tutorial of the 595 shift register ...

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 ...

Electronic enthusiasts, makers and hobbyists searching for a small three or five megapixel camera to use with their next microcontroller project may be interested in the Arducam Mega. Designed to ...

This file type includes high resolution graphics and schematics. When discussing displays, seven-segment displays and LCDs are among the first that come to mind. Each type has its pros and cons. But ...

The new laser diode driver iC-HT permits microcontroller-based activation of laser diodes in CW mode. With this device laser diodes can be driven by either the optical output power (using APC), the ...

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 ...
