ESP 8266 + Neopixel

Vinchiappetto · September 25, 2023, 8:34am

Bonjour à tous,
j'avais sollicité le forum pour un aide sur une carte ESP 8266 pour faire marcher des leds Neopixel. Grâce à vous j'ai pu bricoler un code pour gérer en temps réel par un autre logiciel (Max Msp) mes Leds. Pour info voici le Code (pas très propre mais fonctionnel à ce jour):



/*
  UDPSendReceive.pde:
  This sketch receives UDP message strings, prints them to the serial port
  and sends an "acknowledge" string back to the sender

  A Processing sketch is included at the end of file that can be used to send
  and received messages for testing with a computer.

J'ai deux petits soucis:

je suis obligé de déconnecter les Leds au démarrage de ma carte car sinon ça ne marche pas et les brancher après avoir mis sous tension mon ESP 8266. Je n'ai pas trouvé d'autres solution à ce jour ...
de temps en temps certains modules se déconnectent. Pour info j'alimente les carte et les Leds avec des batteries de téléphone 5V 2.0A et deux modules directement avec des alimentateur 5V 3A. J'ai environs une dizaine de modules sur des adresses IP séparés. Chaque module a entre 30 et 140 Leds et j'envoie des trames au plus vite tous les 25 ms .

Si vous avez des suggestions je vous remercie d'avance de votre aide.
Claudio

Bonjour, j'utilise Google Translate ici, quelques conseils pour vous.

Le choix de la broche de sortie est ici en cause. Selon la façon dont vous connectez la barrette, GPIO 2 ne peut pas être mis en position BAS au démarrage (pas plus que GPIO 0 et 1) ou le mauvais mode de démarrage sera sélectionné.

Cela est probablement dû à la méthode de sortie. Adafruit_neopixel.h utilise une méthode bit-banged pour créer le signal et désactive même les interruptions, ce qui rend le WiFi instable,
Pour les ESP, je recommande plutôt Makuna Neopixelbus comme bibliothèque, et la méthode I2s (DMA) par défaut en particulier. Celui-ci utilisera GPIO 3 (rx) comme broche de sortie et est 100 % stable en combinaison avec le WiFi.

Merci beaucoup Deva_Rishi,
maintenant pas de souci au démarrage ! Ça marche parfaitement
Je vais travailler sur la nouvelle bibliothèque.
