## Summary Arduino ```setup()``` and ```loop()``` run under a Task with a fixed… Stack size of 8KB. Users may want to change this size. This PR adds this possibility by just adding a line of code, as for example: ``` dart ESP_LOOP_TASK_STACK_SIZE(16384); void setup() { } void loop() { } ``` ## Impact None. It adds a new functionality to ESP32 Arduino. If ```ESP_LOOP_TASK_STACK_SIZE(newSize);``` is not declared/used, it will compile the sketch with the default stack size of 8KB. ## Related links fix #6010 https://github.com/espressif/arduino-esp32/issues/6010#issuecomment-992701658 Thanks @igrr for the suggestion!

/*
    ESP32 Arduino creates a task to run setup() and then to execute loop() continuously
    This task can be found at https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/main.cpp

    By default "loopTask" will be created with a stack size of 8KB.
    This should be plenty for most general sketches.

    There is a way to change the stack size of this task by using
    SET_LOOP_TASK_STACK_SIZE(size);
    It will bypass the default stack size of 8KB and allow the user to define a new size.

    It is recommend this value to be higher than 8KB, for instance 16KB.
    This increasing may be necessary for the sketches that use deep recursion for instance.

    In this example, you can verify it by changing or just commenting out SET_LOOP_TASK_STACK_SIZE();

#include <Arduino.h>

// This sets Arduino Stack Size - comment this line to use default 8K stack size

Also in this thread of this same page it is suggested to use SET_LOOP_TASK_STACK_SIZE
