Usage

At24Cxx eeprom;

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

    //256kbit = 256*1024 bits = 262144 bits = 262144 / 8 bytes = 32768 bytes
    //if you're using the ZS-042 board, it has an AT24C32 and uses the default value of 8192
    eeprom = new At24Cxx(i2cBus: Device.CreateI2cBus(), memorySize: 32768);

    return base.Initialize();
}

public override Task Run()
