Project Details
How It Works
How It WorksThe ESP32 uses two independent CPU cores (Core 0 and Core 1) to execute tasks in parallel. By default, the Arduino loop() runs on Core 1, while Wi-Fi and system tasks run on Core 0. Using FreeRTOS, developers can create custom tasks and explicitly assign them to a specific core using xTaskCreatePinnedToCore(). In this project, one task blinks an LED on Core 1 and another task prints data to the serial monitor on Core 0, demonstrating true parallel processing. Each task runs independently with its own stack and scheduling, allowing for real-time multitasking in embedded systems.
Prerequisites
Basic understanding of ESP32 programming, familiarity with Arduino IDE, and knowledge of C++ programming concepts. Experience with basic electronics (LEDs, resistors) is helpful but not required.
