Usage

Max7219 display;

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

    display = new Max7219(Device.CreateSpiBus(), Device.Pins.D01, 1, Max7219.Max7219Mode.Character);

    return base.Initialize();
}

void TestCharacterMode()
{
    display.SetMode(Max7219.Max7219Mode.Character);
    //show every supported character 
    for (int i = 0; i < (int)Max7219.CharacterType.Count; i++)
    {
        for (int digit = 0; digit < 8; digit++)
        {
            display.SetCharacter((Max7219.CharacterType)i, digit, i % 2 == 0);
        }
        display.Show();
    }
}

void TestDigitalMode()
{
    Resolver.Log.Info("Digital test");

    display.SetMode(Max7219.Max7219Mode.Digital);
    //control indivial LEDs - for 8x8 matrix configurations - use the Meadow graphics library
    for (byte i = 0; i < 64; i++)
    {
        for (int d = 0; d < 8; d++)
        {
