FreeRTOS Tick/Tickless via LPTIM

Examples of using the ULP Co-Processor of the ESP32 with simple pulse counting, which I extended for also saving the shortest pulse.

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF implementations. For ESP32 available also with FreeRTOS. ESP8266 and ESP32 support for Ultra Low Power deep sleep app. ESP32 available with PHY Ethernet LAN8720.
