Unlike traditional blocking RTOS kernels, SST uses non-blocking run-to-completion tasks that share a common stack, dramatically reducing CPU and memory overhead. The presentation contrasts SST with FreeRTOS, demonstrates a multi-task Blinky-Button example on an STM32 Nucleo board with a logic analyzer, and shows that SST supports preemption, priority-based scheduling, same-priority arbitration, and rate monotonic analysis — without requiring thread blocking. ## Full article daily.dev links to this article rather than hosting it.
