Hi All,

One thing that Processing has that Processing JS is missing is Serial
access.  I wrote a Java Applet to JavaScript bridge to allow that..
Perhaps it could be adopted by Processing.js?

Wow cool!

Not sure if this makes sense to be part of the main library, since it's a
bit specialized, but thank you for adding to the processing-js community. I
think at least a few people will have a lot of fun with this.

Maybe it would be worth putting together a python or ruby server side client
too? Then you could do dynamic server driven stuff similar to

That's what I mean. I can't imagine what I'd want to communicate with over
serial from a web browser.

I didn't say it was pointless, just that use cases weren't obvious. :)

Hmm, this isn't a very convincing use case.

Hmm, why not just do that server side?

What do you mean exactly? jsserial simply acts as a bridge to java code,
which needs to
be granted access to system resources.

Also, folks, getting the applet setup so it can access the serial port is
more involved than one might think:

If I understand your thoughts correctly... it's actually slower to push
data from hardware through a server like Apache and you have to assume
your user will be running a server also. Using a plug in you are getting
closer to hardware speeds with less disk writing etc. You could set up
some back end services to listen and hold something in memory, but I bet
you it would still be slower than using a Java pugin.

I was pushing MIDI through PHP that was then pushed into the Window
through an iFrame. Which was quick enough really, but not as fast as it
could have been Java hardware access.

No. In the case of an art exihibit - the web (server side) app itself could
be hooked to whatever the serial device is.
Greg's scenerio would involve getting the updates to the serial enabled
browser somehow (comet, etc). You'd still
have some kind of specialized server component in that setup.

Hi Tom,

Yes, in a couple of weeks I plan on putting together a PHP script and
an example using AJAX to grab data from serial through JavaScript..

I agree that it doesn't belong in the main project, just something
that people who are using Processing.js might be interested in since
it one of those things that Processing itself has but Processing.js
doesn't.

Right..  A (self) signed Java Applet that acts as a bridge.  The hard
part was getting through all of the Java and JavaScript sandbox
issues.  Unfortunately when you use JavaScript to access Java Applets
the code that the JavaScript calls acts as if it is unsigned.  This
Applet uses a thread to take care of those issues.

I made it as I am teaching a class in JavaScript/PHP NYU's Interactive
Telecommunications Program that is normally taught in Processing and
one of the things that needs to be accomplished in the course is to
interface with devices via serial.  JavaScript made more sense to me
than teaching how to setup a server and talk serial through PHP.  I do
agree that it is arguable which is the better way to go..

I do think that it makes for an interesting space to explore
alternative input devices.  One compelling thing that I can think of
is that it would work well for experimental assistive technology
(mouth control of a browser or single finger).  In general, I think it
opens the door for a lot experimentation along these lines.

Browsers have been limited to a mouse and keyboard for way too long.
Perhaps certain pages should use physical dials and buttons and others
use gloves with accelerometers..  Isn't Google Maps just ripe for
that??
