Sensors open up worlds of possibilities. SunSPOT is Java compatible sensor technology. Small Programmable Object Technology = SPOT. Working with SunSPOT or other sensors? Experimenting or thinking about it? Come on in! We want to hear all about it!
It’s a piece of hardware that has an array of sensors, an IO port, a radio for wireless communications, a set of LEDs, some switches, a rechargeable battery and a USB port for connecting to a host computer and recharging the battery. You can program the SPOT using Java! There’s no OS on the SPOT, instead, there’s the Squawk VM. You can pretty much program Java ME (MIDP and CLDC) to bare metal! All the device drivers, etc. are written in Java, and there’s a minimal amount of native code that makes all this work. The processor on the SPOT hardware SDK that Sun sells is a 32 bit ARM processor, with 512KB of RAM and 4MB of Flash storage (you can access this via MIDP’s RMS API). SPOTs enabled you to do embedded software development in Java, instead of C or assembly :) ." read much more athttp://developerlife.com/theblog/?p=332
