Bonjour,
Je souhaite inclure 2 librairies dans mon programme, string.h et stdio.h, problème, ces librairies ne sont pas par défaut avec le logiciel Arduino, je voudrais savoir où pouvoir les télécharger ?
D'avance, merci pour vos réponses.
Lucas.
Tu as essayé d'appeler des instructions comme strcpy()?
il ya bien longtemps, on pouvait utiliser les fonctions de string sans importer de lib... (à l'époque l'objet String n'existait pas ouvertement dans Arduino)
Mais je me trompe peut-être... 
tu veux faire quoi qui nécessite ces libs ?
Je veut faire ça :
