Why Cesium RTOS?

Cesium RTOS is a commercially licensed RTOS that is derived from Micrium's µC/OS products. (Micrium's µC/ products have been a top choice of developers in the embedded space for decades in part because of its reliability and the remarkable consistency of its API's from year to year.) We manage Cesium RTOS with the same careful attention to detail as Micrium originally did. 

Cesium RTOS is completely free from modification by open source contributors and is maintained by Weston Embedded Solutions' embedded software experts.  Because the codebase is entirely based on Micrium's reliable and field-proven software, we have preserved all of its safety-critical attributes. Cesium RTOS code repositories were established and captured from Micrium's last commercial release prior to any changes made by open-source contributors.

If you are familiar with Micrium’s µC/OS products, you will find the Cesium RTOS components to be a seamless replacement with no learning curve required by your team.

 

We fully guarantee that all software modules we provide are:

Completely free from modification by open-source code contributors

Entirely based on Micrium's industry-leading and field-proven embedded software

Strictly controlled and maintained by Weston Embedded Solutions engineers under the company's quality assurance process
