cool news !
but many Pc units don't have more rs-232 port..?
Yes I know, I'll try to find some usb adapter soon and make some testing too. but many Pc units don't have more rs-232 port..?
Maybe the serial-to-usb driver won't affect the results that much?
In the worst case it couldn't be csound's or usine's fault but the driver...

I have been doing some test with a piezo connected to an analog pin of an arduino pro board 16MHz/5V.
The arduino is connected to my desktop pc through the rs-232 port , not usb.
In order to avoid overloading of the com port, I made some threshold filtering for the values sent to the desktop pc from arduino.
The result in csound for usine seems to be just fine, about 2% of cpu loading when triggering an usine sampler module with the signal received by the COM port.
At the weekend I'll try to summarize what I have been done, including the arduino and csound code.

Cpu is going to 20% in winxound with ksmps = 500
Cpu is going to 100% in usine with ksmps = 256

it seems that a buffer is overloaded.
i made a test with one photoresistor and one led, very simple.
a link to explain!?
serial opcodes synchronous?

Considering what is written before, Csound could be a great thing for serial adaptation.
As far as I'm concerned, I was only imagining using arduino as a controller, no audio through this card ; that's true that midi is not the answer to interact with the card and audio events.
You have arduino clones that are cheapest. I use a seeeduino.
I just bought an arduino pro, the only I could afford right now. So next week I'll be experimenting with this board and Usine and tell.

:/Hi,
In fact i'm not sure that csound is a good solution now.
Cpu is very high
what kind of test did you do?

Cool ! waiting for a native module,could be a good alternative !
you have an arduino to test caco..? I've a diecimilla here...
Sadly not, creating my hardware via the arduino is on my 'to do' list but so many other projects to do first. Am excited to see what can be done with arduino / csound / usine all hooked up together you have an arduino to test caco..? I've a diecimilla here...

Csound can communicate with arduino via its new serial opcodes added in version 5.14. Maybe use my Csound4Usine user module to run Csound inside Usine, get the data from the arduino and pass it out of Csound4Usine into your patch
Should also be able to manipulate the data easily in Csound beforehand if you wish
There is also an example video by Matt Ingalls demonstrating arduino / csound combination in action - http://gallery.me.com/mattingalls#100119

yes, I said too much... 
very busy this time...
very busy this time...well, i have just no time too, but it's just because I have to turn [large]6[/large] time my neurons in my brain......I'll try to advance on those two points very soon
what is needed for anyone to try to build a com port module in Usine? I'm just a novel on this.
if it's just for raw serial com : the usine SDK and a couple of c++ source files for the serial/com part, already existing on the netor maybe built a module just for serial communication with arduino?
i smell that raw serial com is not enough, it should be coupled with a protocol on both side (like firmata) to be able to be genericbut I'd like to try to process raw data with Usine, data provided by the piezo/mic through arduino serial interface, the original wave shape, not the detected peaks of the waves, etc.
-arduino have to tell to usine : i send some raw audio data
-usine have to understand that what is coming from serial is some raw audio data
... or wath else kind of data
-at max, serial com rate is 115 000 bits per secondIs it possible for Usine to process that amount of raw data in realtime? Or would I have to process the parameters with some arduino library before that?
- usine, for just one audio operation at 44100Hz*16bit deal with 705 600 bits per second
i think you have the answer
but the less you send from the arduino (mean do the max on board), the best for what you can process on the usine side
so, here we are... is there anybody out there (copyright 1979!) ?

so... i ask 'hardly' for a wiki page about this kind of setup 
... specific com port...correct bitrate...virdual midi port...
...and what about the arduino code side ?
at this point, you've said too much or not enough
i have no doubt it could make some user very happy around here !

A possible protocol for a com port with arduino compatibility could be built around:
1-pduino (pure data) coupled with firmata (as headphoner suggested)
2-arduinome serial, which sends raw data from an arduinome to the COM port of a computer.
in both cases, the send/receive protocol is rather well documented.
or maybe built a module just for serial communication with arduino?

And if you have midi messages, you could use uSine...
yeah, I know I could use midi to communicate with Usine, but I'd like to try to process raw data with Usine, data provided by the piezo/mic through arduino serial interface, the original wave shape, not the detected peaks of the waves, etc. Is it possible for Usine to process that amount of raw data in realtime?

I have not get an arduino just yet, so I'm only guessing for the best possible method.

1 - mettre à jour mon site avec le projet
2 - profiter de cette occase pour reprendre la guideline in english for the usiners.
(Je voulais pas commencer à communiquer sur plusieurs forum/sites à la fois je m'attendais à une pluie de questions => si je fais un tuto d'un côté, je mettrais le lien de l'autre, ce sera plus simple et moins chronophage )
I'll try to advance on those two points very soon.

Arduino like other pic embedded with usb com port could generate midi messages (which are serial messages).
If you use a specific com port driver which allows you to set the correct bitrate, you just have to use virtual midi port to receive it...

It seems that the synpad you linked uses this solution. (I imagine)
I did this when I was setting my LABC before switching to real midi signal in order to play robustly with every computer.

the UNO have an usb port, but the drivers make it appear like a COM port to the PC, so it's really plug and play
unfortunatly, usine hasn't a COM module
a COM user module shouldn't be difficult to create, but the real challenge is to implement a communication protocol (firmata or other) between the arduino and usine.
hmmm, I don't have an arduino uno, so I didn't know that :/unfortunatly, usine hasn't a COM module
a COM user module shouldn't be difficult to create, but the real challenge is to implement a communication protocol (firmata or other) between the arduino and usine.
I though about SLIP protocol through COM being able to do the trick because arduino has a library to use it, but it just doesn't work with win7, only winxp!
