Bonjour à tous,
J'utilise un afficheur oled NHD-0420CW-AY3 donc de la marque Newhaven Display, l'afficheur est composé de 4 lignes de 20 caractères. Doc : https://www.newhavendisplay.com/spec...0420CW-AY3.pdf
Le nom du driver utilisé pour mon afficheur est US2066. Doc : http://www.newhavendisplay.com/app_notes/US2066.pdf
Le microcontrôleur que j'utilise dans mon code est un STM32F107RC. Doc : http://www.st.com/content/ccc/resour...CD00220364.pdf
Je dois réaliser un affichage de différents éléments sur mon afficheur selon ce que je choisi de faire avec les boutons.
J'ai 4 boutons, 1 bouton ENTER/MENU, 1 bouton UP/NEXT, 1 bouton DOWN/PREV et 1 bouton CLEAR/BACK.
mon afficheur ressemble à ceci (l'afficheur ne comporte aucun bouton je les gère ailleurs) :
Voici l'énoncer du travail que je dois réaliser :
Interface locale
L’interface locale permettra d’afficher plusieurs informations :
· L’avancement et le résultat de l’envoi des messages aux afficheurs durant le rafraîchissement de ceux-ci
· L’état des zones pendant le reste du temps
· Un menu de configuration accessible avec la touche « ENTER / MENU »
Le menu de configuration devra permettre l’accès à un maximum de paramètres du module. Seuls les paramètres trop complexes à configurer avec cette interface (messages par exemple) n’y seront pas disponibles.
Il faudra, pour ça, disposer de plusieurs types de menus :
· Une liste déroulante permettant d’accéder à des sous-menus
· Une liste à choix simple
· Une liste à choix multiples
· Un menu de saisie d’adresse IP
· Un menu de saisie d’adresse MAC
· Un menu de saisie de nombre (positif / relatif)
· Un menu de saisie de date
· Un menu de saisie d’heure
· Un menu de confirmation
Au début je voulais partir sur un affichage simple des différentes possibilités de ce qui se passe lors de l'appuie sur un bouton. Cependant on peut voir que l'on me demande de pouvoir modifier une adresse IP etc... tous ce que je dois réaliser doit être fait de manière dynamique, c'est à dire que je ne peut pas afficher ce que je souhaite sous forme de variable directement. Je ne sais pas du tout comment m'y prendre pour faire en sorte que ce qui est affiché soit réalisé de manière dynamique avec un rafraichissement permanent notamment par exemple pour les zones qui peuvent changer d'état en direct sur l'afficheur.
Je vous remercie énormément d'avoir pris le temps de lire.
Voici le code source de mon afficheur :
