Meadow.Foundation.RTCs.Ds1307 1.13.0.1-beta

Meadow.Foundation.RTCs.Ds1307

DS1307 I2C real time clock

The Ds1307 library is included in the Meadow.Foundation.RTCs.Ds1307 nuget package and is designed for the Wilderness Labs 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.Ds1307

Usage

private Ds1307 rtc;

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

    rtc = new Ds1307(Device.CreateI2cBus());

    return base.Initialize();
}

public override Task Run()
{
    var dateTime = new DateTimeOffset();
    var running = rtc.IsRunning;

    Resolver.Log.Info($"{(running ? "is running" : "is not running")}");

    if (!running)
    {
        Resolver.Log.Info(" Starting RTC...");
        rtc.IsRunning = true;
    }

    dateTime = rtc.GetTime();
    Resolver.Log.Info($" RTC current time is: {dateTime.ToString("MM/dd/yy HH:mm:ss")}");

    Resolver.Log.Info($" Setting RTC to : {dateTime.ToString("MM/dd/yy HH:mm:ss")}");
    dateTime = new DateTime(2030, 2, 15);
    rtc.SetTime(dateTime);

    dateTime = rtc.GetTime();
    Resolver.Log.Info($" RTC current time is: {dateTime.ToString("MM/dd/yy HH:mm:ss")}");

    var rand = new Random();

    var data = new byte[56];

    for (int i = 0; i < 56; i++)
    {
        data[i] = (byte)rand.Next(256);
    }

    Resolver.Log.Info($" Writing to RTC RAM   : {BitConverter.ToString(data)}");
    rtc.WriteRAM(0, data);
    Resolver.Log.Info($" Reading from RTC RAM : ");
    data = rtc.ReadRAM(0, 56);
    Resolver.Log.Info(BitConverter.ToString(data));

    return base.Run();
}
