Hardware PWM issue

See original GitHub issue

Hi,

I have problem with hardware PWM, cannot run it from .net core application - LED connected to GPIO12. PWM is enabled in /boot/config.txt file (dtoverlay=pwm-2chan) Sample python script works ok.

What I’m missing?

Here is the code sample:

using System;
using System.Device.Pwm;

namespace Sample
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
            var pwm = PwmChannel.Create(0, 0, 100, 1);
            pwm.Start();
            Console.ReadKey();
        }
    }
}

I’m using Raspberry PI 4 with 2GB of ram.

Best regards Fabian

Please try again against the latest dev nuget. This should solve the access violation problem at least.

Run over this issue, so I updated to: <PackageReference Include="System.Device.Gpio" Version="1.1.0-prerelease.20276.1" /> That “System.IO.IOException: Permission denied” bug is fixed.
