Projet de station meteo avec un capteur foudre AS3935

bonjour à tous,

Depuis quelques jours, j’ai commencé un projet de me fabriquer une mini station météo, qui entre autre mesurera la proximité d’un orage. Il existe un capteur foudre Arduino. le AS3935 Lightning sensor.

je possède une carte Arduino R3. J’espère ne pas aller à l’encontre de vos règles. Merci de votre coup de main. Pour l’instant je n’ai pas fait moi même le code car je débute, mais j’ai quand même essayé des codes existant. J’ai téléchargé les librairies du AS3935. Mais je me trouve devant, des erreurs de compilation !?

// AS3935 to be used from within library, it is defined later in main sketch.
// That is up to user to deal with specific implementation of SPI
// Note that AS3935 library requires this function to have exactly this signature
// and it can not be member function of any C++ class, which happens
// to be almost any Arduino library
// Please make sure your implementation of choice does not deal with CS pin,
// library takes care about it on it's own

// is not a requirement

Ça a l’air d’être un souci de caractère non affichable. Le plus simple serait de supprimer ta première ligne et de la retaper à la main (pas de la c/c, tu risquerais de copier le vilain caractère).

Edit : en fait, je dis de la merde, le souci est dans le header, pas ton fichier. Du coup mon conseil s’applique à la première ligne de ton header.
