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 ...

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 ...

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 ...

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.

Serial buses dot the landscape of embedded design. From displays to storage to peripherals, serial interfaces make communications possible. Many serial communication interfaces compete for use in ...

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 ...

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 ...
