I have an issue that I could use some advice with:

I have built a weather station (full of fun wind, solar, temp, etc.

sensors). This weather station uses the "1-Wire" system from Dallas

Semiconductors. The java code I am using is called "simpleWeather"

I'm on an Intel Mac and using a Keyspan USB adapter as the serial port

The "simpleweather" java code uses two libraries (one for the serial

adapter and one for the 1-Wire devices), a class for each sensor

(currently 6 total), and a main class called simpleWeather. All of

the classes use a "package" called simpleWeather.

I have (with help) successfully gotten this to work in Max. I have an

object named "mxj simpleWeather.SimpleWeather" that takes a bang in

its inlet and sends the data from each sensor to its own outlet (6

Here's my problem. When I "bang" the object, Max freezes (spinny

wheel mode) for about 2.5 seconds, and then it gives me my data.

Do any of you have any suggestions for a way that I might be able to

access the data without stopping whatever process is happening in

Do you need more info to answer this - if so what?

..or since it's a serial port, am I better off trying to get the data

through the "serial" object? - tho I'm not sure I can convert/rewrite

Sound like you need multithreading. Luckily in JAVA this is quite

easy. I've uploaded some code that is fairly straightforward and

shows how to do multithreading in JAVA. In particluar, look at the

FileUploader class. It inherits from runnable and has start(), run(),

and stop() methods for managing the thread it contains. You can take

this class, slap your serial/USB stuff in it and it shouldn't block

Great thx! I'm not exactly sure how to implement it, but let me hack

at it for a few days and see if/how it works. I also want to reread

some of the threading that is discussed in "Scheduler, Clocks, and

I might need to upload my main simpleWeather.java for you (or someone)

to see what's all going on under the hood.

Great thx!  I'm not exactly sure how to implement it, but let me hack
at it for a few days and see if/how it works.  I also want to reread
some of the threading that is discussed in "Scheduler, Clocks, and
Executables, Oh My!" from the manual...

I might need to upload my main simpleWeather.java for you (or someone)
to see what's all going on under the hood.

Hey Wes - thanks again. That was really easy to implement and worked great!
