This application note describes how to drive a bipolar
stepping motor with the PIC16F684. The Enhanced
Capture Compare PWM (ECCP) module is used to
implement a microstepping technique known as high-
torque microstepping. The microcontroller’s 8 MHz
internal oscillator allows the signals generated by the
ECCP module to achieve frequencies above the
audible range.

MICROSTEPPING
Microchip Technology Inc. Single stepping, or turning a stepping motor at its rated
step size, results in less than smooth movement.
Microstepping is a technique used to smooth the
INTRODUCTION motor’s movement between full steps and to improve
