Bonjour,
J'ai fait l’acquisition ce matin de la breakout board PN532 d'adafruit (PN532 NFC/RFID controller breakout board [v1.6] : ID 364 : $39.95 : Adafruit Industries, Unique & fun DIY electronics and kits)
qui marche très bien.
J'essaye d'interfacé maintenant un lecteur de carte SD pour pouvoir enregistré mes badges sur carte SD.
Les codes fournit en exemple dans les librairies fonctionne très bien seul, j'arrive a lire mes badges mifare 13.56Mhz sans probleme, pareil pour le code d’exemple Read/Write de la librairie SD, aucun probleme pour écrire/lire un fichier.
Maintenant, quand j'essaye de mettre ensemble les deux codes, apparemment j'arrive a initialisé le lecteur SD mais je n'arrive plus a écrire de fichier dessus, la lecture de badge mifare marche bien par contre.
Et ce que quelqu'un aurait une idée de pourquoi j'arrive pas a les faire travaillé ensemble ?
J'ai mis un code d'exemple en pièce jointe.
dans le moniteur ça me donne:
Initializing SD card...initialization done.
error opening test.txt
Looking for PN532...

Send a character to run the mem dumper again!
Alors que sans décâblé ni rien ma breadboard, les deux codes marche bien si je les essaye séparément.
edit: apparemment c'est un probleme de chip ? ça fonctionne bien sur un 2560 alors que mon Uno a pas l'air de pouvoir.
