control dc motor using lpc2148
A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical rotation in steps. Every revolution of the stepper motor is divided into a discrete number of steps, and for each pulse it receives the motor rotates through one step.
Fig below shows the interface of the Stepper Motor to ARM 7 controller. The stepper motor is connected to Microcontroller using a ULN2003 driver IC. The ULN driver IC is connected to the Port1 pins P1.19 to P1.22 pins. So as the microcontroller gives pulses with a particular frequency to ULN2003, the motor is rotated either in clockwise or anticlockwise.
i'm kasthuri from trichy.i need code for dc motor control using lpc2148 microcontroller.
