Hello World with ESP32 Explained The Espressif Internet Development Framework (ESP-IDF) uses FreeRTOS to make better use of the two high speed processors and manage the numerous built-in peripherals. Let us start our exploration with timer 0. This setup allows combining the easy Arduino-style APIs with the advanced libraries and configuration options of the ESP-IDF. This video is show on how to interface water flow sensor with ESP32 board. The objective of this ESP32 MicroPython Tutorial is to explain how to configure timer interrupts for MicroPython running on the ESP32. The library, along with several others, is packaged together with the ESP32 board files and are automatically installed when the ESP32 board files are installed on the Arduino IDE. ESP32 Reboot system when watchdog timeout.
