esp-idf-hal 0.45.2

A Hardware abstraction layer for Espressif's ESP family of microcontrollers based on the ESP-IDF framework.
//! Blinks an LED
//!
//! This assumes that a LED is connected to GPIO4.
//! Depending on your target and the board you are using you should change the pin.
//! If your board doesn't have on-board LEDs don't forget to add an appropriate resistor.
