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 ...

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 ...

Real operating systems on a tiny microcontroller.

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.

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 ...

Direct sensor-to-microcontroller interface techniques enable the conversion of physical measurands into digital signals without dedicated analogue-to-digital converter chips or elaborate conditioning ...

Liquid Crystal Display (LCD) consists of rod-shaped tiny molecules sandwiched between a flat piece of glass and an opaque substrate. These rod-shaped molecules in between the plates align into two ...
