FreeRTOS
FreeRTOS is a real-time operating system (RTOS) kernel for embedded devices, designed to be small, portable, and scalable. It provides task scheduling, inter-task communication, and memory management for microcontrollers and small processors, enabling deterministic and reliable performance in resource-constrained environments. It is widely used in IoT devices, automotive systems, and industrial automation.
Developers should learn FreeRTOS when building embedded systems that require real-time responsiveness, such as IoT sensors, medical devices, or automotive control units, where tasks must execute within strict timing constraints. It is essential for projects needing multitasking on microcontrollers with limited RAM and flash memory, as it offers a lightweight and open-source alternative to proprietary RTOS solutions.
