I'm having fun hacking the Arduivis code and patch (model 4), for parsing multiple data streams from Arduino into Max. It works seamlessly and is very transparent.

I hate having a hole in my understanding though; he separates each discrete data stream using ascii 32 - Serial.print(" "); but in the accompanying Max patch, it's not parsed anywhere, it simply uses [sel 13 10] like what we used to do back in the olden times.

Here is a very sparse patch and sketch (with comments) to illustrate. I don't actually have a practical problem, as I say it works perfectly; there's just one tiny part that is opaque to me.

My understanding is Serial.print("Hello world.") gives "Hello world." not "72 101 108 108 111 32 119 111 114 108 100 46". So a space " " is just a space unless I've misunderstood.

thanks for chipping in. Hmmm; in my Max patch above, if you use [print] to debug, you'll see that ascii 32 is there in the stream at the Max end, it's just, erm, ignored somewhere.

It would appear that [fromsymbol] ignores the 32, but by the time the stream reaches that object, all the parsing is already done.

Now that I understand what your question really was...FWIW fromsymbol doesn't ignore the 32, itoa has already changed it into a space.

Aha. Thanks for clarifying that Rick. The 32 is an 'actual' space, not just some randomly chosen delimiter (like a comma or semicolon), it separates the individual data streams. As you say, [itoa] does the parsing for me (us).

Cheers, now I can continue to pretend I know what I'm doing . . .

The space (aka 32) is used because parsing commas adds an extra part to pak but commas are a hassle to deal with in Max in the first place. Tried to make it easier and compact. Thanks for using arduivis y'all!!! :)
