Ich möchte die Ripple-Effekt-Animation codieren, wie sie in den ersten 7 Sekunden dieses Videos zu sehen ist .

So funktioniert mein Code jetzt. Es verwendet 9 Schieberegister (74HC595); 8 für die 64 Spalten und 1 für die 8 Schichten.

Wie soll ich das machen? Ich verstehe den folgenden Code kaum. Es zeichnet einen expandierenden Würfel.

/* Voxel Shield Sketch
  Controls a Light Emitting Diode(LED) Cube of 8x8x8 voxels arranged
  by 64 columns(anodes) and 8 layers(cathodes).

Code für Welleneffekt eines 8x8x8 LED-Würfels Arduino

Vicatcu · Answer 1

Um den Programmfluss in diesem Code zu verwenden, müssen Sie im Grunde das, was Sie dort sehen, in verschiedene Frames aufteilen. Ersetzen Sie dann die Schleife durch Aufrufe jeder Frame-Funktion, gefolgt von draw(). Frames sind Momentaufnahmen des Würfels mit gleichmäßigen zeitlichen Abständen. Je mehr Frames Sie haben, desto "flüssiger" sieht die Animation aus, aber desto mehr Flash-Speicher benötigt das Programm.

In den Frame-Funktionen (z. B. box, box2, box3) Ihres Beispiels sind die Bits, die im Frame-Puffer (dh der Würfel-Array-Variablen) auf "1" gesetzt sind, die LEDs, die in diesem Frame eingeschaltet sind, und diejenigen, die es sind auf "0" gesetzt sind in diesem Rahmen ausgeschaltet. Jede Schicht hat 8 LEDs, also gibt es ein Bit pro LED. Sie müssen nur Ihr LED-Muster pro Rahmen abbilden.

Das Erstellen der fest codierten Rahmenfunktionen kann auf diese Weise von Hand erfolgen, indem die Rahmensequenz per Skript erstellt wird. Ich denke, es gibt Beispiele von Leuten, die diesen Teil an einen PC delegiert haben, der Frames über die serielle Schnittstelle an den Arduino sendet, um aufwändigere / flüssigere Animationen zu erhalten, ohne alle Frame-Funktionen im Flash speichern zu müssen.
