Dupa mai multe zile de teste am constatat ca se blocheaza uneori dupa cateva deci de minute, alteori dupa zeci de ore, si cautand solutii, am dat de articolul An over engineered way to unlock a door in care se mentioneaza folosirea catelului de pasa (watchdog), care poate debloca microcontrolerul in caz de functionare anormala..
Cateva poze cu de la testelele in care am pus partea de watchdog si de contorizarea a timpului cat functioneaza, deoarece la autoresetare se reia de la zero:
Am facut un filmulet numit LED controlat prin retea sau wireless (5):
Sketch-ul derivat din cel de pe site-l http://www.lucadentella.it/ la care am pus partea de contorizarea din exemplul RBBB_server al librariei Ethercard
si partea cu watchdog-ul este:

Cu ajutorul datelor de pe site-ul italian si cu informatii de la Alex si de la Andrei am pus si parola:
Am facut un filmulet numit LED controlat prin retea sau wireless (6) in care se vede cum reactioneaza pagina web in functie de parola introdusa corect sau gresit, in plus, informatiile sunt actualizate la cca. 30 secunde:

La adresa http://www.ec.in.th/index.php?route=cms/article&article_id=41 este o schema foarte frumos prezentata de conectare la o placa Arduino a unui placi de retea cu ENC28J60:

Am facut inca 2 filmulte, incarcand sketch-ul din articol, punand si un LED portocaliu de 10mm din generatia veche a Microelectronica la pinul A0:
Salut.
RăspundețiȘtergereImi place acest proiect, dar am o intrebare, aceste componente sunt ok?
http://goo.gl/YFviC7 + http://goo.gl/SreUTw
da, sunt ok modulele... adic aplaca de retea si clona Arduino ;))
