Digital-to-Analog Conversion or simply DAC, is a device that is used to convert a digital (usually binary) code into an analog signal (current, voltage, or electric charge). Digital-to-analog conversion is the primary means by which digital equipment such as computer-based systems are able to translate digital data into real-world signals that are more understandable to...

Introduction LCD is the most common display devices used in different dedicated applications be it the instrumentation, medical equipment, panels, robotics etc. It is quite easy to interface it with the microprocessors or microcontrollers. We can directly interface a LCD with microcontrollers, however, for interfacing with microprocessors, we need a peripheral device such as 8255....

Interfacing a stepper Motor Definition: These stepper motors are made of permanent magnet rotor with stator field excitation. Unlike the DC motors which move continuously, the stepper motors move in incremental steps. The stepper motor is a type of DC motor with the field placed on the rotor in the form of permanent magnets with...

Generating the Ports for interfacing There are two techniques or methods for interfacing i/o devices, these are: i/o-Mapped I/O- In this method, the i/o device have separate address space and instructions exclusively for inputting or outputting the data from/to the devices. Instructions for reading/writing memory are different than i/o instructions.IN and OUT are used for...
