Java on a chip for robotics: http://www.parallax.com/javelin/index.asp
I just got one of these for a small robot I got for a song as a promotional offer (www.arrick.com) on ebay. -----Original Message----- From: Vincent Greene [mailto:[EMAIL PROTECTED]] Sent: Monday, February 10, 2003 3:00 PM To: [EMAIL PROTECTED] Subject: [jug-discussion] JVM on a Chip Try: http://www.ibutton.com/TINI/ and http://www.ibutton.com/ibuttons/java.html TINI is very cool. It is only a JDK 1.1 level implementation, but it has so much peripheral support in so little space: DIMM size board with multiple serial ports, 1 Wire interface (see ibutton stuff), Ethernet, embedded TCP/IP stack, Telnet and FTP servers. Cost starts at like $60 in quantities of ONE. Development boards with connectors to let you exploit the board and develop hardware and software with it cost around $100 with one of the boards. When I am done with my current electronics project (keypad to open the garage with multiple codes, time restrictions, storage of entry exit codes and times, RS485 interface, and, oh yeah, a Christmas light timer), I plan on buying a TINI development board and screwing around with it. Maybe a secure web server to check what time the garage door last opened. It could make for a good presentation on the world of embedded Java in the future if there is any interest. For a more practical use of one of these, see: http://mp3elf.net/ TINI based MP3 music player with LCD, Ethernet, IR. Play music files from your PC anywhere in the house - all powered by Java.
