Is it possible to use 8 peggy board all together to make a large led screen to display time temp and or scrolling text.

Yes, although it hasn't yet (to my knowledge) been done, and it would probably involve some (straightforward) programming. The Peggy 2 boards tile side-to-side seamlessly so that they can make an extended display. There is an onboard I2C interface-- a type of multipoint serial port --that can be used to send data to multiple Peggy 2 boards, from an appropriate controller-- either one of the boards dedicated as master, or (for example) an external Arduino used as a serial-TWI converter.

1. I'm interested in doing that (and do have *A LOT* of questions Oops! ) but I have no programming experience, is there anyone here willing to do something like that ?
2. I'd also like to ask if there's anyone controlling the Peggy in real time using Processing (if that's even possible, I don't know)
3. Is there anything already done(code) to make a Peggy a big "audio spectrum analizer" display ?
Thanks !

I don't know if anyone will volunteer for it, but typically at least *some* programming experience is needed to do things like this. Peggy is, of course, a good place to learn programming. Wink

Our video peggy example shows one way to do this-- we used the video camera module in processing to control the Peggy, through its I2C interface.

>Is there anything already done(code) to make a Peggy a big "audio spectrum analizer" display

I don't know if that's been done. It does seem like a somewhat obvious thing to do....

What about Pure Data ? Is it possible to use it with the peggy ? If yes, is there anyone using it ? I've just started with it Cool
Thanks!

I do not know of anyone using pd, but the interfaces are pretty flexible-- you could certainly make that work if you wanted to.
