This Processing sketch takes data from the serial port, graphs it, and writes it to a text file with a time stamp if there’s a significant change in any of the incoming values. It expects five values between 0-255 in ASCII, separated by tabs, and ended by a carriage return and newline.

The text file it generates is tab-delimited, and can be read easily in a spreadsheet.

A Wiring/Arduino program to send data to this sketch follows at the end.

I got tired of the problems with the various serial server solutions for Flash, so I wrote this Processing sketch to do the job. It’s functional, but I still need to tweak it a bit. But it will allow you to connect a Flash movie to a serial port by making an XML socket to localhost in order to access the serial port. Sample test ActionScript code is at the bottom.

Thanks to Shawn van Every for the latest updates, and Actionscript 3 code.

The fullscreen library for processing allows you to set the screen resolution to match your Processing sketch’s size so that it can take over the full screen. It also includes key bindings so that you can enter and exit fullscreen mode while the application is running.

Thanks to Mike Bukhin for the link.

Dan Shiffman’s written a nice library to access the sudden motion sensor on the macbook and macbook pro. He based it on a couple other open source libraries. Below is a code sample for it that draws a plane on the screen and moves it as you tilt the computer.
