Bonjour,
Je débute sur Arduino, j'ai pour projet de lire un fichier sur mon serveur Web, afin de mettre à jour des variables sur mon Arduino.
J'ai acheté Ethernet Shield (ENC28J60), j'utilise la libraire EtherShield.h.
Je me suis inspiré des exemples, mais je recois un message d'erreur que je ne comprend pas lors de la compilation :
"
EtherShield_readpachube.pde:138:1: error: unterminated #ifdef
EtherShield_readpachube.pde: In function 'void loop()':
EtherShield_readpachube:143: error: invalid conversion from 'void ()(uint8_t, uint16_t)' to 'void ()(uint8_t, uint16_t, uint16_t)'
EtherShield_readpachube:143: error: initializing argument 4 of 'void EtherShield::ES_client_browse_url(prog_char*, char*, prog_char*, void (*)(uint8_t, uint16_t, uint16_t))'
"
Le code que je suis entrain d'adapter :
