- https://www.hackster.io/muhammad-aqib/how-to-use-oled-display-with-arduino-arduino-oled-tutorial-233985
Que faire avec cet écran ?
Mode d'emplois
Installer la bibliothèque esp8266-oled-ssd1306 (depuis croquis -> inclure un bibliothèque -> gérer les bibliothèques puis tapez SSD1306 dans la recherche.
créer ses propres fichiers image à afficher
Faites une image en respectant ces règles :
- monochrome
- format PNG
- taille : 48 X 48 pixels (c'est la taille du logo du Science Hack Day mais l'écran faisant 128X64 pixels, j'imagine qu'on peut aller jusque là ?).
utiliser le site https://www.online-utility.org/image_converter.jsp
choisir "mono - bi-level bitmap in least significant-byte first order"
cliquer sur " select format"
importez votre fichier image et récupérez le fichier que vous utiliserez pour le programme Arduino.
Afficher un logo Science Hack Day défilant
ouvrir une nouvelle fenetre de programme arduino. copiez-collez le programme principal cliquez à droite sur la flèche vers le bas et choisissez "nouvel onglet"
saisissez le nom "image.h"
Copiez-collez le code plus bas ou le code correspondant à votre image
