(PresseBox) (Texas, ) .
- Port Immediately Available for Stellaris LM3S6000 and LM3S2000 series MCUs
- Demonstration Web Server Application For EK*-LM3S6965 Evaluation Board
- Commercial Licence Available with OpenRTOS
- Safety Critical Application Support Available with SafeRTOS
- New Kernel Interrupt Management Configuration Enables High Priority Interrupts with Very Low Timing Jitter To Run Concurrently With The Kernel™ announces the immediate availability of a port for Luminary Micro's new Ethernet-enabled (LM3S6000 series) and CAN-enabled (LM3S2000 series) Stellaris® family of ARM® Cortex™-M3 microcontrollers. The software is available for download from; immediately providing a proven real-time scheduler to developers utilizing new Stellaris family members. Further reducing time-to-market, has also released a free web server application demonstration that executes on the Luminary EK*-LM3S6965 Ethernet evaluation board. is a portable, open source, miniature Real Time Kernel for use in embedded applications. is free to download licensed under a modified GPL, and can be used royalty free in commercial applications, subject to the adherence of license conditions. A commercially licensed solution, OpenRTOS™, is available from WITTENSTEIN high integrity systems – who can also provide professional support and development services.

WITTENSTEIN also offers SafeRTOS™, an IEC 61508 Safety Integrity Level (SIL) 3 compliant solution based on that provides an ideal solution for a wide range of safety-critical applications.

“ provides a valuable option to our customers as it is both easy to use and highly efficient in real embedded memory-constrained applications," said Jean Anne Booth, Chief Marketing Officer of Luminary Micro. “The ability to move from an open-source solution to a commercial licence provides our customers with excellent flexibility.” allows engineers to easily use the powerful features and extended resources of the new Ethernet-enabled (LM3S6000 series) Stellaris family members. The demo application features an embedded web server that permits two way exchanges of dynamically generated data between the web browser and the embedded device utilizing the Stellaris MCU’s integrated Ethernet MAC and PHY. The V4.3.0 port also features a new configuration that permits increased flexibility in interrupt management. This allows high priority interrupts with very low timing jitter to run concurrently with, enabling high-bandwidth communications through the devices communications ports.

“We are excited to work with Luminary and their range of high-performance microcontrollers, " said founder Richard Barry. "Many designers are moving to high-performance microcontrollers such as those from Luminary Micro, and are finding the pure interrupt-driven model does not scale as processing power increases. The community helps ensure a simple, compact Real Time Kernel is available to make migration as simple and painless as possible."

FreeRTOS.orgTM is a portable, open source, mini Real Time Kernel that is free to download and royalty free, even in commercial applications. Ports exist for many different processor architectures and development tools. Free support is provided by an active user community, with commercial support offered by WITTENSTEIN high integrity systems. is licensed under a modified GPL.
