ST has worked with its partner in Java tools, IS2T, to create ready-to-use Java development kits for its STM32 microcontrollers. The STM3220G-JAVA Starter Kit combines an evaluation version of IS2T's MicroEJ Software Development Kit (SDK) and the STM32F2 series microcontroller evaluation board providing everything engineers need to start their projects.

The MicroEJ Software Development Kit provides extended features to create, simulate, test and deploy Java applications in embedded systems. Support for Graphical User Interface (GUI) development includes a widget library, design tools including storyboarding, and tools for customising fonts.

GeeseWare contributes to the ecosystem supporting Java for STM32 with its complete one-stop-shop hardware and software solution. It combines IS2T's MicroEJ SDK with a comprehensively featured development board supporting STM32F2 and STM32F4 microcontrollers.

The ARM Cortex-M core processor technology of ST's STM32 microcontroller is capable of supporting rich human-machine interfaces in miniature, low-cost, power-sensitive applications, making STM32 the ideal platform for Java to enter the embedded world, said ST. The tools announced by ST support Java development on STM32F2 devices, which use the ARM Cortex-M3 processor, and STM32F4 devices featuring the Cortex-M4. Cortex-M4 adds DSP extensions and a floating-point unit.

STM32 microcontrollers combine Cortex-M series processors with high-performance peripherals and large number of product variants to provide choice as well as advanced performance and functionality. All devices are pin, peripheral, and software compatible, allowing developers to adapt or scale their designs quickly and without high engineering costs. The STM32 range now comprises over 300 devices, offering designers a selection of variants integrating up to 1MB of Flash memory, connectivity-centric USB/Ethernet/CAN or OTG devices, ultra low-power microcontrollers, and high-performance variants.

ST supports STM32 developers with resources such as evaluation kits, drivers, firmware, programming tools, debugging tools, which can be used with development environments and tools from leading independent vendors.

The STM3220G-JAVA Starter Kit is available immediately from ST or distributors, priced at Rs.18,272.25 ($349). The full MicroEJ development kit is available from IS2T (

GeeseWare development boards are available from GeeseWare ( and the company's distributors in North America, Israel and France.
