[QUESTION] turn specific pixel on or off? about md_parola

[MajicDesigns]

Just use the MD_MAX72xx library setPoint() directly to turn on the pixels.

If you are doing this as a once off testing code, just use MD_MAX72xx. If you are using it in your code always then you get the MD_MAX72xx library pointer used by MD_Parola using the getGraphicObject() method.

thank you for your fast help!
in case there are some other arduino noobs like me out there

MD_Parola Display = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
MD_MAX72XX *pM;

  // use setPoint() to turn on/off a specific pixel
  pM = Display.getGraphicObject();
  pM->setPoint(5, 0, true);
