Splitflap
Split-flap es un sistema integrado de especificaciones de software y hardware para controlar pantallas mecánicas split-flap. Proporciona un controlador de pantalla split-flap y controladores de hardware distribuidos para gestionar la rotación de módulos de solapas mecánicas utilizando motores paso a paso y microcontroladores.
El proyecto incluye un generador de arte vectorial para solapas para crear archivos de diseño SVG imprimibles para caracteres y fuentes personalizados. También cuenta con herramientas para el diseño de paneles cortados con láser para producir componentes de hardware y placas frontales de módulos combinados.
El sistema cubre el control de hardware distribuido a través de una topología de controlador en cadena y control de movimiento de motor paso a paso utilizando rampas de aceleración. Incluye calibración de dispositivos de hardware a través de posicionamiento de inicio basado en sensores y monitoreo de la salud del hardware utilizando comprobación de errores de bucle.
