• Application: The example code is M480 GPIO control 4-Phase, 8-Beat stepper motor.
• BSP Version: M480 Series BSP CMSIS V3.03.001
• Hardware: NuMaker-PFM-M487 V3.0

This code uses M480 timer to control I/O that can drive stepper motor by Darlington IC(ULN2803). This document includes everything you need to know about controlling a 28BYJ-48 stepper motor with the ULN2003 driver and M480 timer.

The 28BYJ-48 is one of the cheapest stepper motors you can find. Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors.
