Windows IOT - Stepper, Servo and DC motors

Windows IOT motor drivers and demo for PCA9695, ULN2003 and L298N chipsets controlling Servo, Stepper and DC motors respectively.

After working on numerous motors within various projects over the years, I decided it was time to create libraries for chip-sets, for ease of use. In the following post we will look into controlling Servo, Stepper and DC motors.
 

It is now available in Nuget

 

 Install-Package IOTMotorDrivers -Version 1.0.0-Pre

 

Please note all these libraries will build under any platform but it requires the Platform to be in "ARM->Remote device" to Debug (I will make it work with all platforms eventually)

  
DC Motors
 
Upon research, L298N H Bridge happens to be the best driver for a DC motor and it is great for controlling wheels. Based on my experience with PCA9685 and its reliable PWM output, I decided to extend golaat's library to support the H Bridge as follows:

// DC Motor Pins private const int PCA9685_DC1_Pin = 15, DCInputAPin = 17, DCInputBPin = 27; private const int PCA9685_DC2_Pin = 14, DCInputCPin = 23, DCInputDPin = 24; 
// Driver for PCA9685 
pwmDriver = new PCA9685(); 
pwmDriver.SetDesiredFrequency(60); 
// Driver for L298N 
dcMotorDriver = new L298N(new L298NMotors { 
    ENPin = PCA9685_DC1_Pin, 
    INAPin = DCInputAPin, 
    INBPin = DCInputBPin 
}, new L298NMotors 
{ 
    ENPin = PCA9685_DC2_Pin, 
    INAPin = DCInputCPin, 
    INBPin = DCInputDPin 
}, pwmDriver); 
// Start and control Motor 1
dcMotorDriver.Start(motorSelection: L298NMotorSelection.Motor1, speedPercent1:
 
 
Stepper Motor
 
When you usually buy a 28BYJ-48 step motor, it comes with a ULN2003 driver containing loads of python libraries. Below is a simple library to control the motor, get real-time updates and simulate LEDs on board for fun :D

// Step Motor Pins 
private const int Step_IN1 = 6, Step_IN2 = 13, Step_IN3 = 19, Step_IN4 = 26; 
// Driver for ULN2003 
stepMotorDriver = new ULN2003(Step_IN1, Step_IN2, Step_IN3, Step_IN4);
// Its an async function so could await it until completes the task
await stepMotorDriver.Start(revolutions: 1, isClockwise: false, progress: null);
