Micrium’s kernels have been ported to a wide variety of CPU architectures. We provide not only the ports themselves, but also example projects for popular evaluation platforms. Each project is an ideal starting point for a new µC/OS-based application.


Commercial Use: The example projects are intended for evaluation use only. Developers seeking to use Micrium products commercially must contact Micrium sales to obtain the proper license(s).





Ports and Drivers Not Listed: If you are interested in a port or driver for a hardware platform that is not listed here, you can contact Micrium to inquire about the possibility of commissioning a custom port.
