Distinct between close and open event

[adopilot]

First at all thanks a lot on effort, it is really easy to listen events.

I am trying to listen GIPO on Raspberry pi 4 b

Following your examples I do get event raised on connecting GPIO with GND.

But I do not know how to make distinct between closing and opening circuit.
Whenever circuit is closed or open I do get event.
Perhaps I am missing something, can you please help me to find distinct between open and close event.

Here is my code so far

 class Program
    {
        static async Task Main(string[] args)
        {
            Console.WriteLine("Staring app");
            using var controller = new GpioController();
            var clock = 0L;
            var paused = false;
            var collection = new SubscriptionCollection
            {
                ClockEnabled = true, // Optional, defaults false
                ClockRate = TimeSpan.FromMilliseconds(500) // Optional, defaults to 500ms
            };
            collection.Subscribe(6, PinMode.InputPullUp, PinEventTypes.Falling);
            var subscriptionService = collection.Build();

            await foreach (var subEvent in subscriptionService.Run(controller, CancellationToken.None))
            {
                if (subEvent.IsClock && !paused)
                {
                    clock += subEvent.Delta;
                    Console.WriteLine($"Tick {clock}");
                }
                else
                {
                    Console.WriteLine($"Pin is {subEvent?.PinNumber ?? 0}");
                    clock = 0L;
                }
            }
           
        }
    }

Hello @adopilot !

You can use controller.Read(subEvent.PinNumber) and check that against PinValue.Low or PinValue.High

Keep in mind if this means open vs close depends on if you choose InputPullUp or InputPullDown when subscribing, as this choice "flips" the meaning of High vs Low.
