Quiero codificar la animación del efecto dominó como se ve en los primeros 7 segundos de este video .

Así es como funciona mi código ahora. Utiliza 9 registros de desplazamiento (74HC595); 8 para las 64 columnas y 1 para las 8 capas.

¿Cómo debería hacer esto? Apenas entiendo el código de abajo. Dibuja un cubo en expansión.

  by 64 columns(anodes) and 8 layers(cathodes).

Básicamente, para usar el flujo del programa en este código, debe dividir lo que ve allí en marcos distintos. Luego reemplace el bucle con llamadas a cada función de cuadro seguida de dibujar(). Los marcos son instantáneas del cubo espaciados uniformemente en el tiempo. Cuantos más fotogramas tenga, más "suave" se verá la animación, pero más memoria flash ocupará el programa.

En las funciones de cuadro (p. ej., caja, caja2, caja3) de su ejemplo, los bits que se establecen en "1" en el búfer de cuadro (es decir, la variable de matriz de cubo) son los LED que están encendidos en ese cuadro, y los que están establecidos en "0" están desactivados en ese cuadro. Cada capa tiene 8 LED, por lo que hay un bit por LED. Solo tiene que trazar un mapa y su patrón de LED por cuadro.

La creación de las funciones de cuadro codificadas de forma rígida se puede hacer a mano de esta manera, escribiendo la secuencia de cuadros. Creo que hay ejemplos de personas que han delegado esta parte a una PC que envía cuadros al Arduino a través del puerto serie para obtener animaciones más elaboradas y fluidas sin tener que almacenar todas las funciones de los cuadros en el flash.
