Existe-il une bibliothèque Arduino Modbus RTU RS485 pour le M5Stack Core + module LAN PoE?
-
J'aimerais faire communiquer mon M5Stack core + module LAN PoE avec un Automate Unitronics via le protocole Modbus RTU RS485 (half-duplex: R - => B & R+ => A). Je suis donc à la recherche d'une aide pour le développement du programme sur Arduino. Je n'ai pas trouvé de bibliothèque ou un exemple de programme, je suis donc un peu embêté.
merci pour votre aide.
