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 ...

The project illustrates the serial interfacing of Hitachi compatible 2×16 LCD modules with PIC16F84 or PIC16F628 microcontroller unit. Before doing serial interfacing LCD with PIC microcontroller, it ...

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 ...

There are plenty of SPI interface screens on the market, but few of them have the charm of the good old Nixie tube. [Tony] decided to whip up a simple three-Nixie module that could be addressed via ...

Voltage-to-current converters that feed grounded loads are common in industrial measurement and control applications. The conventional "textbook" circuit uses both positive and negative supply rails.

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 ...

In the relentless pursuit of higher performance at a system level, Integrated Device Manufacturers (IDMs) have become well versed in developing digital interfaces that are able to operate at high ...
