What is Stepper Motor Interfacing with LPC2148 about?
This document discusses interfacing a stepper motor with an LPC2148 microcontroller. A six-wire unipolar stepper motor is used with a ULN2003 driver chip. The microcontroller outputs control signals to rotate the stepper motor clockwise and counter-clockwise in alternating full and half steps. Program code is provided to output the step sequence from port 0 pins to drive the motor.
