Contrôle de moteur pas à pas sur commande DMX
Contrôleur de moteur pas à pas piloté en DMX, sur ESP32 : la position et la vitesse sont commandées par deux canaux DMX distincts, avec détection d’obstacle par perte de pas.
Clément SAILLANT, pour Hémisphère — création de l’Opéra de Montpellier, 2023
Un canal DMX est utilisé pour la commande de la position du moteur
Un autre canal DMX est utilisé pour la commande de la vitesse du moteur
Une fonction affine est utilisée pour convertir la valeur DMX en position ou vitesse
La position et la vitesse sont stockées dans des variables globales
Une fonction est utilisée pour la sécurité si un obstacle est détecté par la perte de pas du moteur
moteur : 34HS59-6004D-E1000
Angle de pas: 1.8 deg
Résolution de l'encodeur: 1000PPR(4000CPR)

Questions
How big is the DMX ESP Stepper controller PCB?
It measures 88.3 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMX ESP Stepper controller use?
47 parts, built around the ESP32-WROOM-32, SP3485CN-L, PCF8574T and AMS1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DMX ESP Stepper controller KiCad files?
From the electron-rare/DMX_ESP_Stepper-controller repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/Level shifter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMX ESP Stepper controller design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
