tout à l air de fonctionner sauf l affichage des pages web, il y a plein de caractère spéciaux qui viennent à l écran !
le resultat
quelqu'un a une idee ?
Merci Seb

Program: eth_websrv_SD
Description: Arduino web server that serves up a basic web
page. The web page is stored on the SD card.
Hardware: Arduino Uno and official Arduino Ethernet
shield. Should work with other Arduinos and
compatible Ethernet shields.
2Gb micro SD card formatted FAT16
Software: Developed using Arduino 1.0.3 software
Should be compatible with Arduino 1.0 +
SD card contains web page called index.htm
