Express Logic has announced at Embedded Systems Conference (ESC) in San Jose that its royalty-free real-time operating systems (RTOS) and USBX USB Host/Device stack now support Luminary Micro's Stellaris LM3S3000 series and LM3S5000 series ARM Cortex-M3-based microcontrollers.

ThreadX is Express Logic’s royalty-free RTOS. Its royalty-free business model should make ThreadX attractive for high-volume devices.

ThreadX and USBX for the new Stellaris devices are designed for use with the ARM/Keil RealView tools from ARM.

The Stellaris family consists of six members of the Stellaris LM3S3000 USB series and fourteen members of the Stellaris LM3S5000 CAN+USB series. It also includes an integration of USB On-the-Go and host capability in the ARM Cortex-M3 architecture.

According to Jean Anne Booth, chief marketing officer of Luminary Micro: “ThreadX presents a small memory footprint with an easy-to-use, rich set of system services. Embedded developers will appreciate the capabilities of ThreadX using the evaluation version and demonstration application available for our new Stellaris evaluation kits.”
 
A free evaluation version of ThreadX and a demonstration program in source code form are available for Luminary Micro’s Stellaris LM3S3748 USB Host/Device Evaluation Kit and LM3S3768 USB On-The-Go Evaluation Kit. 

ThreadX and USBX are available in full source code form, royalty free, at license prices starting at $12,500.
