Could be a possibility but I was hoping for an object that would be able to
read I2C directly without adding an arduino since most smaller arm boards do
have some I2C pins onboard.
If the machine Pd is running on has an I2C port and is running linux
then it
probably won't.

full scale.
For instance a 24-bit DAC could be sent 16 16-bit full-scale streams and
not clip. Only if 16-bits is considered full scale does that make it

as full scale, then you have
a lot of headroom but your signal to noise ratio is not as good, and
maybe something like this is happening in the default MacOS headphone

The soundcard will always clip above +1 and below -1, and sometimes even
within those limits (if the interpolated waveform between samples goes
over the limit).
Pd will not clip internally, so you can calculate with larger numbers as
long as you scale them back down before listening to them.

A more robust solution is to use SLIP to encode the packets in the
Arduino and [slipdec] from pd-extended to decode them.

Hi all,
We've been after some sensors for motion detection on the RPi and Martin
Peach spotted these (thanks again Martin!)

They're fairly new and I've

Hey Martin,
Good to hear you've got one of these too.
Yes I meant [comport] with the xbee rather than [hid] sorry, getting my
physical input objects confused.
Will check out the links you provided as part of my getting up to speed.
So, managed
-point format is the same at both
ends.

Martin , thank you for everything, I got it working now even with
floating point numbers, here is the rundown of the method
[solved]
BUT BEFORE FOLLOWING THIS, NOTE THAT FLOATING POINT NUMBER IS SOMETHING
I attached a patch that should reconstruct a long if it's bigendian,
although it doesn't give 100 for the sequence you provided...
The floating point numbers are more difficult, you need to separate the
sign, exponent and mantissa and then put it all together.

to the analog inputs of an Arduino and send the data to
Pd which reads it using [comport].

Hi Martin,
Is this with Maxbotic and if so which one? I'm going to be running the
sensor with an RPi as standalone so presume it's a similar setup (I
believe comport runs fine on RPi)
I use the MB1010 (MaxSonarEZ1). The analog output is very low

for littleendian.
Floats are harder but still possible. The main difficulty is in
splitting the incoming stream in the right places. (I think ASCII is not
orders of magnitude slower, and it is also less ambiguous).

It's probably safer to get the server to send the numbers as ASCII text,
to avoid disagreements about endianness and floating-point representation.
Then, to extract the numbers, you could use [moocow/bytes2any] or make a
custom parser using [pdlua].

Why not do an FFT and measure the variance of the channels?
For instance white noise has maximum entropy and all the bins of its FFT
will be more or less the same, while a sine wave has low entropy and one
bin will be much larger than the others.

), but you can use it to set a range.
there are a few other drawbacks though:
-you have to deal with individual names for the templates etc. (or make
an abstraction and build your own state-saving)
-accessing the data is not as easy as with a built-in gui element.
bis denn!
