Hi,
I’m doing a project that needs data from tcp and from serial ports into TCPin DAT and SERIALin CHOP.
is there any way to get more than 60 frames per second out of these objects? The quantisation artefacts are making me sad at the moment. 
cheers,
Rod.
Whats generating the data?
The tcpip in DAT will log all data it receives, regardless of rate.
I’d suggest using it and the Serial DAT as well for that reason.
You can convert the data to CHOP values afterwards.
Whats the Serial In CHOP ?
The Serial CHOP outputs serial messages and reads in just one byte per cook. (pretty limited)
Is that the one you meant?

sorry, yes I’m using the serialin DAT and the TCPin DAT.
when I middle-click on them it tells me they are running at 60fps.
does that mean that, say 9600baud coming in gets reduced to 60fps no matter what once it gets to the DAT?
cheers,
Rod.
It means the messages (however many are received) are output 60 times per second.
But many samples could potentially come out each cook.
How are you using the samples?
Are you intending to run at 60fps and you need multiple data points per frame calculation
somewhere?
some of it’s EEG data from Brainbay via Neuroserver (TCP)
the main thing I’d love to be able to do would be to feed the raw EEG into the spectrum CHOP but it complains that the sample rate is too low. I might just solve it by getting Brainbay to filter it into separate power levels for frequency ranges and send it out as separate data channels. Or the parametric equaliser CHOP seems okay for dealing with low frequency stuff too.
The Dataq box [url]http://www.dataq.com/products/startkit/di149.htm[/url] is getting a feed from a doppler heart sensor, so it’s basically audio so it would be great to be able to feed that through the spectrum CHOP or other audio-oriented CHOPs.
after the gig panic’s over, I’ll write up what I did and how for the wiki.
Rod.
Another option, is to just let the Serial DAT keep the last 500 or so messages,
then use a DAT to CHOP to convert it to channels.
Also just confirmed, the OSC In, Out CHOPs do support high sample rates.
