Controlling a Bipolar Stepper Motor
bentejuy Sep 09, 2015 Tags MotorStepper InterfaceGPIO Bipolar

Bipolar stepper motors tend to have just two motor windings; they are called bipolar because these windings must change polarity in a determined order sequence to move with each step. They require more circuitry to be adequately controlled, but in exchange they offer some advantages compared to unipolar motors.

In the previous post, we saw that stepper motor control is relatively simple with Raspybot, although currently it only supports the class InterfaceGPIO as layer of connection with the Raspberry Pi. In this example I'll show how to control a stepper motor in a non-blocking manner.

A Class for Unipolar Motor Stepper - Part I

One of the first classes built in Raspybot was the MotorStepper, which allows me to control stepper motors. I thought it was fascinating to be able to control motors step by step because those are the ones that allow us to interact actively with the Raspberry PI. Here, I detail how to control a motor with MotorStepperUnipolar class.
