Nucleus SmartFit for STM32

Nucleus is a proven, stable, and optimized RTOS largely deployed in embedded applications. It integrates power management features (DVFS, Deep Sleep Modes, and Power/Clock Gating) enabling engineers to take full advantage of the latest power saving technologies in today’s silicon. It has an outstandingly small footprint (as small as 2 KBYTE).


The Nucleus SmartFit is an all-in-one combination of IDE and RTOS pre-configured for specific hardware environments. The version for the STM32 is adapted to the STM3240G evaluation board based on the STM32F407 MCU. It allows to jump-start RTOS based software development for the STM32 and it is the ideal tool for converting bare metal implementations (applications without OS usage) to an RTOS-based environment by keeping the overhead for the OS minimal.
