q regarding strings
Aug 21st, 2009, 10:58pm  
hey guys\girls,

I have a very simple question regarding  strings.

I have a arduino passing a series of sensor values trough the serial interface.

this is what the string looks like...

eg: 510,150,150,150,150,450,450,890

I have written the basic code in Processing to show these values in a window.
I can't figure out how to split the string up and display the values in the window.

I have had a look at one page in "Physical Computing at ITP" and I can split the string and get the values to show in the the applet.

I've tried using the method described in link in article named "Visualizing Sensor data with Arduino"

could someone please she some light on this... I'm pretty new to the serial communication programming.


edit: I forgot to add I can work out how to split the string into a array to display in the applet. I would prefer to split it onto strings to show them in the window. These readings get updates every second.

Thanks heaps...

did you check out http://processing.org/reference/split_.html ?
just split your string into an array of strnigs. use a for loop to display them all. And as your string gets updated your arrays gets updated too and should display the new values...

Yeah, just had a look at that. Got it working using that method.

I was looking at that exact code and completely over looked that... Embarrassed

Take a look at the Java documentation when you need to do fancy stuff with strings. There are a ton of great methods that do all sorts of cool stuff!

Here's the link: Java String Documentation
