Thank you Si for your reply and for your suggestion -  I don't want to appear unpolite but what i need is not a workaround but instead is to understand if webduino is the right answer to process POST request or not... it looks like nobody faced the same needs.

I have to make it fool and spoof proof: beside the POST request I like most over GET, I cannot accept that a HTTP POST request will bang the board... you know what I mean.

Thank you anyhow,
Andrea

Thank you for your quick reply PaulS - I need POST in order to make parameters not visible from the URL... that said, this doesn't solve the question: is webduino capable to retrieve (or at least to avoid to hangup!) POST parameters (apparently as stated) or not? Did anybody experienced such a behaviour?

Regards,
Andrea

Hi everybody - My environment: Arduino 0018, original Arduino 2009, original Ethenet Shield (1st version with no reset), Win XP, all browsers (FF 3.6.8, IE 8, Safari 5.0.1)

 I've made a lot of test on HTML pages that would rely on webduino's POST retrieving capabilities with no success - all I get as a result is:

1 - Arduino hanged-up (reset needed to get a page again)
2 - a web page with the following content (that never stops):

POST to parsed.html requested.

URL tail = ''
Parameters sent by POST:
= ''
= ''
= ''
= ''
= ''
...
...


Everything is good as soon you use GET parameters...

Am I the only one encountering such a kind of problems?
Mant thanks in advance for your attention...

Regards,
Andrea

Direi di sì - nel caso dell'alta impedenza metterei un pull-down da 4k7.

L'uso di un patch-panel BNC mi sembra una buona idea - sull'attribuzione ingresso/uscita dei singoli pin di Arduino non dovrebbero esserci limiti di sorta...

Buona sperimentazione...

Salve - espongo qui di seguito come mi comporterei in caso analogo:

D - "Devo adattare..."
R - in ingresso verso Arduino mi sentirei di dire che non importa (immagino che l'uscita dell'apparechhio sia già correttamente terminata) comunque si tratta di segnali TTL. In uscita da Arduino verso l'apparecchio temo, nel caso l'input sia terminato su 50 Ohm, sia necessario un buffer, anche tipo emitter follower

Ritardi e riflessioni potrebbero entrare in gioco quando le frequenze salgono e/o la durata degli impulsi si assottiglia: non so in quali domini avviene la connessione.

Spero di aver correttamente interpretato le domande...


Saluti,
Andrea

Hi - I've designed a small and simple circuit (that plugs on the POWER connector so it doesn't require any soldering on the shield) that allows to reset the original Ethernet Shield (1st version) when powered from an external power source without interfering with the code upload functionalities.





Note: resistor R1 is mounted vertical

Enjoy!
