I am working on a project to make a Netduino Plus 2 control the drive hydraulics on a small tractor and I stumbled over some trouble using the PWM class. In the simple example below I have marked in bold where the compiler does not recognize the PWM class.

 

I have noticed that the list of usings contains the NetduinoPlus using where as all the code examples I have seen on-line all use the ..Netduino; using.

 

I hope that some body can find a moment to comment on this - thank you.

 

using System;

using System.Net;

using System.Net.Sockets;

using System.Threading;

using Microsoft.SPOT;

using Microsoft.SPOT.Hardware;

using SecretLabs.NETMF.Hardware;

using SecretLabs.NETMF.Hardware.NetduinoPlus;

 

 

namespace RGB_Led

{

    public class Program

    {

        public static void Main()

        {

            PWM redLed = new PWM(PWMChannels.PWM_PIN_D9, 200, 60, false);

            

            redLed.DutyCycle = 60;

 

            Thread.Sleep(Timeout.Infinite);

        }

    }

}

Hi Henrik,

Sorry for the troubles. Newer versions of .NET MF introduced a new integrated PWM class--and so Visual Studio is presumably seeing the integrated PWM class (which has a different set of constructor parameters, etc.)

You can still use the old class though. Just add SecretLabs.NETMF.Hardware.PWM.dll as a reference to your project and then add "SecretLabs.NETMF.Hardware." in front of your PWM declaration/constructor.

Like this:

SecretLabs.NETMF.Hardware.PWM redLed = new SecretLabs.NETMF.Hardware.PWM(PWMChannels.PWM_PIN_D9, 200, 60, false);

Does that get you up and running?

Welcome to the Netduino community!
