Splitflap
Split-flap ist ein integriertes System aus Software- und Hardwarespezifikationen für den Betrieb mechanischer Split-Flap-Displays. Es bietet einen Split-Flap-Display-Controller und verteilte Hardware-Treiber, um die Rotation mechanischer Flap-Module mithilfe von Schrittmotoren und Mikrocontrollern zu verwalten.
Das Projekt enthält einen Vektor-Flap-Artwork-Generator für das Erstellen druckbarer SVG-Designdateien für benutzerdefinierte Zeichen und Schriftarten. Es bietet zudem Tools für das Design lasergeschnittener Paneele, um Hardwarekomponenten und kombinierte Modul-Frontplatten zu produzieren.
Das System deckt die verteilte Hardwaresteuerung über eine Daisy-Chain-Controller-Topologie und die Schrittmotor-Bewegungssteuerung unter Verwendung von Beschleunigungsrampen ab. Es umfasst die Hardware-Gerätekalibrierung durch sensorbasierte Home-Positionierung und Hardware-Health-Monitoring mittels Loopback-Fehlerprüfung.
