PWM usage in custom class

Hello,

 

I have a Netduino plus 2 and I am making a motor controller with it

 

I have a class with the folowing constructor:

 

# region MotorControl Constructor        public MotorControl(Cpu.PWMChannel pwmpinleft ,Cpu.PWMChannel pwmpinright, Cpu.Pin releasecontroller, Cpu.AnalogChannel analogpin, Cpu.Pin rpmpin, int mvToma, string name)        {                        Debug.Print("New controller motor instance created.");            PWMspeedFwd = new PWM(pwmpinleft, PWMFrequency, CurrentPWMFwd, false);            PWMspeedRev = new PWM(pwmpinright, PWMFrequency, CurrentPWMRev, false);            ReleaseController = new OutputPort(releasecontroller,true);            Debug.Print("PWM and release ports created.");

 

 

The class is created using the following line:

 

 /// <summary>        /// Left UGV motor        /// </summary>        public static MotorControl motorleft = new MotorControl(PWMChannels.PWM_PIN_D5, PWMChannels.PWM_PIN_D6, Pins.GPIO_PIN_D0, Cpu.AnalogChannel.ANALOG_0, Cpu.Pin.GPIO_Pin15, 20, "Motorleft");

 

However, it looks like the pwm pins are not initialized? When I want to measure the signal using a scope I get no signal.

 

Do I initialize the PWM pins the correct way?

 

I set PWM values using the following code:

 

PWMspeedFwd.DutyCycle = i;

 

With i varying between 0 and 1. Is this correct or should it be between 0 and 100 %?

 

Thanks in advance and with best regards,

 

Jeroen.

Haven't used PWM much myself but I remember reading something lately about issues with initializers of static variables - are you seeing the dubug messages?

Thanks, that solved the problem
