It was Pd extended, it worked like a charm, now im on the project i was halted from yesterday when i got caught onto this, thank you again!

holy... that was it, that solved it

thanks a lot for your good will to help this blind man out of this trouble lol cheers!

just tested what you uploaded, got this:

netreceive: failed to sett SO_BROADCAST
arduino 1
... couldn't create

and nothing else. i dont get unknown input command msgs anymore, even after setting the proper port and arduino analog pin. im on Win 7 Professional.

now, i moved the moocow folder you attached to my original pd patch folder and got this:

no more moocow errors anymore, then i set the port, got the firmata 2.5 message, then set pin a0 and got the endless stream of unknown input command msgs that change value when i move the pot. i think we're pretty close, but still not there :/

arduino-test.pd
Thanks for answering! This is driving me mad lol.. Heres the patch attached, its the arduino test utility for Pduino.

comport is fine, the messages you see there are when you havent set the correct port yet, you select the correct one (in this case port 7) and it doesnt bugger anymore.

Im using pd vanilla 0.49 on Windows, so i have to check any moocow references and change them for "list tosymbol" and "list fromsymbol"? ...ive read on forums moocow shows these warning messages but only when running on windows.

So, to recapitulate, firmata is properly installed on the arduino, and its actually giving out correct output data, but cant get them to be recognized by Pd, hence the unknown input command messages, pretty sure the moocow issue is the culprit but still cant get my head around it.

Hello everyone, ive got this problem while trying to connect my arduino to Pd. Already installed firmata, used firmata test app to check its ok, and it is. But when i open the arduino-test pd patch, i get this:

So, i select the port im using and the A0 pin which is the one with the potentiometer im gonna use, and i get thousands of UNKNOWN_INPUT_COMMAND messages, i turn the pot and the values go from 0 to 1000, and the pd device info block has Firmata 2.5 so its recognizing the device, but cant go beyond that. Any ideas? I see that moocow is missing (and that could be relevant), but couldnt get anything using the "find externals" function.
