Interfacing a Stepper Motor with ARM Controller LPC2148

Another useful machine interfaced to the computer system is the Stepper motor. A Stepper motor is a digital motor because each input pulse results in discrete output or discrete steps as it traverses through 3600 which means the shaft rotation by definite angle called step angle. Stepper motors are DC motors that move in discrete steps. They possess multiple coils that are organized in groups referred to as phases. By energizing each phase in sequence, the motor will rotate one step at a time. Stepper motors are available in various sizes and styles as well as electrical characteristics. Nowadays, the use of ARM controllers is in limelight. The ARM controllers are basically designed to target the 32 bit microcontrollers. These controllers provide excellent performance and are available with latest and enhanced features. The ARM controllers are suitable for 32 bit embedded applications. The state of the art presented in this paper is the interfacing of Stepper motor with ARM controller LPC 2148
