Key Features
- Very small memory footprint, low overhead, and very fast execution.
- Tick-less option for low power applications.
- Equally good for hobbyists who are new to OSes, and professional developers working on commercial products.
- Scheduler can be configured for both preemptive or cooperative operation.
- Coroutine support (Coroutine in FreeRTOS is a very simple and lightweight task that has very limited use of stack)
- Trace support through generic trace macros. Tools such as FreeRTOS+Trace (provided by the FreeRTOS partner Percepio) can thereby record and visualize the runtime behavior of FreeRTOS-based systems. This includes task scheduling and kernel calls for semaphore and queue operations.

“Experience has shown that the trade of the East is the key to national wealth and influence.”
—Chester A. Arthur (1829–1886)
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
