 A New Approach To Embedded Software

OPENRTOS is a small, efficient embedded kernel based on the highly successful FreeRTOS. Our unique approach provides the ultimate flexibility for professional software development. Developed by FreeRTOS.org and released under a modified GPL license, FreeRTOS is completely free to download and use, even in commercial applications. It is simultaneously released by WITTENSTEIN as OPENRTOS, with full commercial support and licensing. There is no 3rd party or open-source content or licensing and the features and quality are tightly controlled and superior to many ‘commercial only’ alternatives. The software is integrated with USB, FAT and TCP/IP providing a complete embedded platform at low cost.
