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)
 {
 // read time
 DateTime dt = rtc.DateTime;
 Console.WriteLine(dt.ToString("yyyy/MM/dd HH:mm:ss"));
 Thread.Sleep(5000);
 }
