STM32-JAVA

Fully-integrated Java development environment and solution

for STM32 MCUs

Data brief

Features

A single DVD-ROM incorporating:

• STM32Java Software Development Kit built on

• Several Java Platforms (JPFs) for STM32:

Quick Start JPFs and Production JPFs

• JPFs can be extended to support specific

hardware of the application board

• Embedded (EmbJPF) and Simulation

(SimJPF): the very same Java binary code

functionally validated on the SimJPF runs on

the sibling EmbJPF

• MicroUI (Micro User Interface) and MWT

(Micro Widget Toolkit) graphical libraries:

– Targets all major graphical display buffer

organizations, monochrome and full color

displays

– Event engine to handle very efficiently and

at high speed haptic sensor drivers:

buttons, joystick, touch panel, etc.

• MicroUI (Micro User Interface) and MWT

(Micro Widget Toolkit) new graphical libraries

available from version 3:

– UI Layer library: Chrom-ART Accelerator™

management for rich user interfaces.

– UI Motion, UI transition libraries: to create

specific pages motion (linear, ease,

bounce, elastic)

• Tools included:

– Font designer to design fonts in many ways

– Story Board designer to quickly specify

possible human-machine interaction with

the application

– Front Panel designer to extend the Java

platform simulator

• Very small and efficient Java virtual machine:

– Flash: less than 30 KB

– RAM: less than 1.5 KB

– Startup time: less than 2 ms at 120 MHz

• 1-year subscription, with hardware dongle

Description

Take advantage of the benefits of object-oriented

programming in Java to develop general purpose

STM32 applications, in particular, applications

with a smartphone-like look and feel graphical

user interface (GUI) with STM32Java.

All of the well known advantages of the Java

design concepts are available: interface versus

implementation, inheritance and composition,

polymorphism, garbage collector (GC),

multi-tasking, etc.

Software productivity, agility, scalability and

security are improved compared to traditional

developments in C/C++ code.

Applications can mix C code (legacy

control/command code for example) with code

developed in Java. STM32Java provides efficient

mechanisms to interface the 2 worlds, Simple

Native Interface to call C functions from Java

code and Shielded Plug to exchange data

between the 2 worlds.

STM32Java provides everything required to

easily and very quickly develop feature-rich GUIs,

relying on the Model-View-Controller (MVC) triad,
