Blinky program

This is the infamous blinky program. The goal is to turn on the LED for 1 second, turn it off for 1 second, and repeat indefinitely.

#include "freertos/FreeRTOS.h"  // pdMS_TO_TICKS
#include "freertos/task.h"      // vTaskDelay()
#include "driver/gpio.h"        // gpio_set_direction(), gpio_set_level()

const int LED_PIN = 5;

void app_main() {
    gpio_set_direction(LED_PIN, GPIO_MODE_OUTPUT);

    while (1) {
        gpio_set_level(LED_PIN, 0);
        vTaskDelay(pdMS_TO_TICKS(1000));
        gpio_set_level(LED_PIN, 1);
        vTaskDelay(pdMS_TO_TICKS(1000));
    }
}
