[PD] pduino and FSRs

Yes, I've got the latest version....maybe a silly question...but could it be
that Pduino is optimised for sensors working on a supply of 5v. because the
phidget voltage dividers i've got my FSRs attached to come with a
potentiometer that alters the resistance of the circuit...with pduino i can
only activate 2 at a time before it all grinds to a halt...on arduino2PD i
can activate all six without any problem. Strange.

I've never run on Vista before, so I can't say much about that. I have run
on Debian, Ubuntu, and Mac OS X. It shouldn't matter what is generating the
data on the arduino, the messages coming to Pd via the serial port should be
all the same. 

Are you using the latest version:

Hello Hans-Christoph, I am using PD 0.39.3 extended. on a windows vista
system. Its PD that crashes, or "stops working" as Vista so nicely puts it,
when I connect the FSRs.
I have arduino connecting via wireless xbees at 19200 baud.
I also use an infra red distance sensor that gives no problem.
I've been routing the data from the FSRs through the autoscale object.
Maybe I should find a way to reduce the amount of data being sampled...every
40ms for example? How would I do that?

Which program crashes? Which version are you using? You will get a lot of
data, from 6 sensors, Pduino/Firmata will read them all every 20ms. I have
never seen a crash using [arduino], except when I unplug the arduino when Pd
is connected to it, so I suspect the problem lies elsewhere.

I have a little problem using Pduino and some force sensing resistors that I
am using in conjunction with phidget voltage dividers....they seem to crash
the program as soon as I activate more than 1 at a time..... 
Should I be applying some sort of filter to the data stream?
Arduino2PD seems more robust, allowing me to activate all 6 analog inputs at
