Schematic 1 (Source Code - 1)

Stepper Motor Driver Schematic with PIC18F4550 Microcontroller PIC


Schematic 1 corresponds to the fist source code mentioned in the main tutorial page where stepper motor is coded to run in a loop continuously in single stepping mode. Please refer the main tutorial projects page for downloading and description of the stepper Motor interface with PIC18F4550.

In second schematic the Stepper motor is running in three different stepping modes. The LED's on RB 0, RB 1 , and RB 2 shown in the schematic indicates the modes the mode in which the stepper Motor is currently operating. Find the necessary code for this schematic in the main project page.
