Splitflap
Split-flap est un système intégré de spécifications logicielles et matérielles pour piloter des affichages mécaniques à volets (split-flap). Il fournit un contrôleur d'affichage à volets et des pilotes matériels distribués pour gérer la rotation des modules de volets mécaniques en utilisant des moteurs pas à pas et des microcontrôleurs.
Le projet inclut un générateur d'illustrations de volets vectoriels pour créer des fichiers de design SVG imprimables pour des caractères et polices personnalisés. Il propose également des outils pour le design de panneaux découpés au laser pour produire des composants matériels et des façades de modules combinées.
Le système couvre le contrôle matériel distribué via une topologie de contrôleur en guirlande (daisy-chain) et le contrôle de mouvement de moteur pas à pas utilisant des rampes d'accélération. Il inclut l'étalonnage des appareils matériels via un positionnement d'origine basé sur des capteurs et la surveillance de la santé du matériel utilisant la vérification d'erreur en boucle (loopback).
