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();
