Hi to you all,
and thanks for the extream quality of your forum and discutions!

I'm working on a "all in a box" system including PD and Arduino.

Who of you have an idea of speeding up the booting process ??

Pc+freebsd+arduino ?
Win2K + arduino ?
Tiny linux systems ?
Embeded systems (but what about the interfacing with arduino) ?
...
Any idea ?

Thanks to you all
(and sorry about my english)
Alexis (from Paris France)

I got Pduino working on an NSLU2 embedded debian system. Booting off flash memory with a stripped down linux install is a good way to speed up boot time.

Thanks Nestor!
I just checked this solution on http://www.nslu2-linux.org/wiki/Debian/HomePage : looks great!

Is the NSLU2 enough for realtime sequencer or sampling ?
Do you have any latancy problem with it ?

Thanks a lot for your answer

Alexis

The slug is real nice. Mine runs debian-arm which has quite a repository for precompiled packages.

The slug does not have a graphics card. This is just fine, because you can forward an X.org session to another machine via ssh to do your patching.
The slug does not have a sound card. There are packages on the repo to support ALSA and maybe Jack?? Pd needs to run with a floating point emulator to do any audio as well...

I'll tell you, I originally intended on using the NSLU2 as a way to encode wah pedals and make an OSC/UDP stream. That way, you could "spread the load" across a network of specialized devices: Arduino does ADC for sensing, the NSLU2 (build orifinally as a network device, booting from flash) builds the network packets, and a machine with powerful processors/GPU and a nice DAC does the audio and video. Maybe I'll revive the project once I build a new 'lab'...
