Meadow.Foundation.RTCs.Ds323x

Ds323x I2C family of real time clocks (DS3231, DS3231M, DS3232)

The Ds323x library is included in the Meadow.Foundation.RTCs.Ds323x nuget package and is designed for the Meadow .NET IoT platform.

This driver is part of the Meadow.Foundation peripherals library, an open-source repository of drivers and libraries that streamline and simplify adding hardware to your C# .NET Meadow IoT applications.

Installation

You can install the library from within Visual studio using the the NuGet Package Manager or from the command line using the .NET CLI:

dotnet add package Meadow.Foundation.RTCs.Ds323x

Usage

Ds3231 sensor;

readonly TimeSpan timezoneOffset = new TimeSpan(-7, 0, 0);

public override Task Initialize()
{
 Resolver.Log.Info("Initialize...");

 sensor = new Ds3231(Device.CreateI2cBus(), Device.Pins.D06);
 sensor.OnAlarm1Raised += Sensor_OnAlarm1Raised;

 return base.Initialize();
}

public override Task Run()
{
 sensor.CurrentDateTime = new DateTimeOffset(new DateTime(2024, 1, 1), timezoneOffset);

 Resolver.Log.Info($"Current time: {sensor.CurrentDateTime}");
 Resolver.Log.Info($"Temperature: {sensor.Temperature}");

 sensor.ClearInterrupt(Ds3231.Alarm.BothAlarmsRaised);

 sensor.SetAlarm(Ds3231.Alarm.Alarm1Raised,
 new DateTimeOffset(new DateTime(2024, 1, 1, 1, 0, 0), timezoneOffset),
 Ds3231.AlarmType.WhenSecondsMatch);

 sensor.DisplayRegisters();

 return base.Run();
}

private void Sensor_OnAlarm1Raised(object sender)
{
 var rtc = (Ds3231)sender;
 Resolver.Log.Info("Alarm 1 has been activated: " + rtc.CurrentDateTime.ToString("dd MMM yyyy HH:mm:ss"));
 rtc.ClearInterrupt(Ds323x.Alarm.Alarm1Raised);
}
