Usage

Connect sensor to the microcontroller.

static void GetTimeFromDs1302()
{
    GpioController controller = new GpioController(PinNumberingScheme.Logical);
    using Ds1302 rtc = new(13, 12, 14, controller);

    if (rtc.IsHalted())
    {
        Console.WriteLine("RTC is halted!");
    }
    else
    {
        rtc.Halt();
        Console.WriteLine("RTC was halted now!");
    }

    var currentTime = new DateTime(2022, 8, 5, 18, 31, 0);
    Console.WriteLine(currentTime.ToString());
    rtc.DateTime = currentTime;

    while (true)
