EN DEUX MOTS

SS est 10
SI CS!= 10 il faut manager 10! comme SS

"déouyblement" de la libriire; AtherCard?.h --> Ethercarde.h
suppression du define Ethernet
objet ENc28J60 aulieu de Enc28J61?

ouf sur le 3.3V seul, a tourne sur les deux objets
fonctionne aussisisur la prise plug si 3.3 + pug, mais pas sur la prie 3.3V

quand j'empile le pluggabm;, conso 180 mA (110 sans le plug) avec alim externe, plus quie 20mA!
focntioone sur le pluggble
mis pas sur le 3.3V

en résumé, il semble que je ne puisse pas traverser le plug!
