As such, the entire solution occupies minimal Printed Circuit Board (PCB) area. This allowed me to keep the board size down to the 10x10 cm. org I added many new functionalities. Moreover, the ESP32 contains 10 capacitive sensing GPIOs, that detect touch and can be used to trigger events, or wake-up the ESP32 from deep sleep, for example. How do I increase the stack size (or check for overflow), with ESP32/MongooseOS? The stack in question is the one that is called into C/C++ from JavaScript via an FFI function, this being called from a closure when the api_timer. The warning should tell me that the information shown about the stack size is wrong: I did create the App Task with 110 stack units (each 4 bytes) so it should show 440 bytes, but it shows only 308 bytes.
