Part No:MPInex-Micro-JAVA-Javelin
The Javelin Stamp module is a 24-pin DIP module programmed in a subset of
the Sun Microsystems Java language.
The Javelin Stamp module is a powerful module programmed in a
hardware-oriented subset of the Sun Microsystems Java language. In addition
to providing lots of RAM and EEPROM space and a well-known structured,
object oriented programming language. The Javelin Stamp module
firmware can
also run multiple background tasks. Java resources are easily accessible due
to the number of java programming books at your favorite book store.

Features :
-
The instruction codes for
the Javelin are fetched and executed from a parallel SRAM
-
The Javelin has 32k of
RAM/program memory with a flat architecture. No more program banks, and
no more tight squeezes with variable space.
-
The Javelin has built in
Virtual Peripherals (VPs) that take care of serial communication, pulse
width modulation and tracking time in the background.
-
Serial communication is
buffered as a background process. When writing programs, all you have to
do is periodically check the buffer.
-
Delta-sigma A/D
conversion.
-
D/A conversion is
accomplished in the background as a continuous pulse train delivered by
an I/O pin. The pulse width modulation VP can also be used for
generating pulse trains, frequencies, and D/A conversions in the
background while your foreground code is free to perform other tasks.
