We will guide you through a complete project example to help you fully … Read more

Introduction to FreeRTOS Tasks

by
Introduction to FreeRTOS Tasks

FreeRTOS is an open-source real-time operating system kernel, and tasks are its core execution units. Each task has its own stack and execution context, managed by the scheduler based on priority. In embedded systems like the ESP32, tasks can run on different CPU cores, supporting preemptive scheduling (higher priority tasks can interrupt lower priority tasks). … Read more
