AN906: Stepper Motor Control Application Circuit Using the PIC16F684 MCU

Stepper Motor Control Circuit using the PIC16F684 microcontroller. The Enhanced Capture Compare PWM (ECCP) module is used to implement a Micro-Stepping technique known as high-torque Micro-Stepping. The microcontroller 8 MHz internal oscillator allows the signals generated by the ECCP module to achieve frequencies above the audible range
