< p > La communauté Arduino nous a déjà fourni de nombreuses bibliothèques qui peuvent être directement utilisées pour rendre cela beaucoup plus simple. J’ ai essayé quelques bibliothèques et trouvé que la bibliothèque < a href = "https://github.com/adafruit/Adafruit_SSD1306" > Adafruit_SSD1306< / a > était très facile à utiliser et comportait une poignée d’ options graphiques, c’ est pourquoi nous allons utiliser la même chose dans ce tutoriel.

< p > Nous avons simplement établi une communication SPI entre le module OLED et Arduino .
Etant donné que l’ OLED fonctionne sur 3V-5V et consomme très peu d’ énergie, il n’ a pas besoin d’ alimentation externe. Vous pouvez simplement utiliser des fils pour établir la connexion ou utiliser une planche à pain comme je l’ ai utilisée pour faciliter l’ expérimentation.

< p > pour afficher une image, les données bitmap doivent être stockées dans la mémoire du programme sous forme de directive PROMGMEM. En termes simples, nous devons indiquer à l’ affichage OLED quoi faire avec chaque pixel en lui transmettant une séquence ou les valeurs d’ un tableau, comme indiqué ci-dessus. Ce tableau contiendra les données bitmap de l’ image.< / p >
< p > Cela peut paraître compliqué, mais à l’ aide d’ un < a href = "http://javl.github.io/image2cpp/" > outil Web< / a > , il est très facile de convertir une image en valeurs bitmap et de la charger dans le tableau ci-dessus.< / p >

< p > Bien qu’ ils soient petits (environ un pouce de taille), ces écrans produisent une belle image nette de 128x32 ou 128x64 pixels. Connecter l’ écran à un Raspberry Pi est également facile grâce au support de 3,3 volts de l’ écran et à l’ interface I2C ou SPI.< / p >
< p > Ce guide vous expliquera comment connecter l’ écran à un Raspberry Pi et comment installer et utiliser la bibliothèque SSD1306 Python. Assurez-vous que votre Raspberry Pi utilise le dernier système d’ exploitation Raspbian.< / p >
< h3 id = "câblage-raspberry-pi" > Câblage Raspberry Pi< / h3 >
< p > Vous pouvez connecter un OLED au Raspberry Pi à l’ aide de l’ interface I2C ou SPI du Pi.

< p > Notez que le câblage ci-dessus utilise le bus matériel SPI du Raspberry Pi pour communiquer avec l’ écran. Si vous ne l’ avez pas déjà fait avec votre Pi, veillez à éditer le fichier blacklist.conf pour commenter la ligne qui désactive SPI. Redémarrez votre Pi et vous devriez voir que les fichiers /dev/spidev0.0 et /dev/spidev0.1 sont maintenant disponibles.< / p >
< p > L’ utilisation du matériel SPI est idéale pour obtenir la réponse la plus rapide de l’ écran. Toutefois, si vous avez besoin de plus de flexibilité dans l’ utilisation des broches, vous pouvez utiliser une implémentation SPI logicielle avec 5 broches GPIO numériques gratuites. Voir l’ exemple d’ utilisation du code à la page suivante pour plus d’ informations sur la configuration du logiciel SPI.< / p >

< p > Sous les valeurs de configuration se trouve la configuration de la classe d’ affichage. Vous pouvez créer deux classes, < strong > SSD1306_128_32< / strong > ou < strong > SSD1306_128_64< / strong > . La classe SSD1306_128_32 représente un affichage 128x32 pixels et la classe SSD1306_128_64 représente un affichage 128x64 pixels.< / p >
< p > En plus de la taille de l’ affichage, vous configurez également l’ interface utilisée par l’ affichage dans ces lignes. Les deux premiers exemples utilisent l’ interface I2C et doivent uniquement spécifier une broche RST. En interne, la bibliothèque SSD1306 recherchera le numéro de bus I2C par défaut pour la plate-forme et l’ utilisera - si vous avez suivi le câblage dans ce guide, vous devez être prêt! Toutefois, si vous devez contrôler explicitement le numéro de bus I2C, le troisième exemple montre comment le spécifier avec un paramètre i2c_bus.< / p >
< p > Les trois derniers exemples montrent comment configurer l’ interface SPI. Pour le SPI basé sur le hardare, vous devez seulement spécifier la broche RST, la broche DC et le périphérique SPI matériel. Utilisez l’ un de ces exemples si vous avez suivi les instructions de ce guide. Toutefois, si vous souhaitez utiliser une interface SPI logicielle, le dernier exemple montre comment spécifier chaque broche SPI pour un Raspberry Pi (pour un BeagleBone Black, il suffit de modifier les valeurs des broches en fonction des broches que vous utilisez).< / p >
< p > Décommentez la ligne d’ affichage appropriée en fonction de la taille de votre affichage et de l’ interface que vous utilisez pour communiquer avec celui-ci. Le code suppose que vous utilisez un écran 128 x 32 pixels communiquant via le matériel I2C. Toutefois, si vous utilisez un écran ou un protocole différent, < strong > décommentez la ligne appropriée< / strong > . Assurez-vous de < strong > commenter toutes les autres lignes< / strong > qui ne sont pas utilisées!< / p >
