M5Dial and graphics and canvas and sprite: why so hard to figure out??

  • U

    I am trying to do sprites or canvas or something in the M5 Dial and had a hell of a time getting it to work. In the end I am not sure I did it right.

    I see things about canvas and sprites but I don't know the relationship, and I can't figure out what is a M5Dial call, M5Canvas or what.

    In the end I did:

    M5GFX display;
    M5Canvas canvas(&display);

    then followed with:
    auto cfg = M5.config();
    M5Dial.begin(cfg, true, true);
    display.begin();

    seems inconsistent but worked.

    In my loop I did:
    display.startWrite();
    canvas.createSprite(240, 240);
    canvas.fillScreen(0xABE1);
    canvas.setTextColor(WHITE);
    canvas.setTextDatum(middle_center);
    canvas.setFont(&fonts::Orbitron_Light_32);
    canvas.setTextSize(1);
    canvas.drawString("The Title", M5Dial.Display.width() / 2, 15);
    canvas.pushSprite(0,0);
    display.endWrite();

    In the rest of my code I always did stuff like:
    M5Dial.Display.drawString("To Print", 30, 90);

    Are there M5Dial.Display equivalents to what I am trying to do?

    The display is silky smooth without flickering now but I don't quite get it.
