Not enought RAM... how can I execute code in another module?

[nastiliano]

Hello everyone,

Sorry for this essential question, but I can't find exactly what I want.

I have this kind of code inside my "main.py":

import _thread
import anotherClass #(anotherClass.py)

...

def thread_1():
while True:
print("thread_1")
time.sleep(1)

def thread_2():
anotherClass.myClass() #in myClass there's infinite llop obviously

_thread.start_new_thread(thread_1 , ())
_thread.start_new_thread(thread_2 , ())

But, I have no idea how to execute this (boot.py, main.py and anotherClass.py) correctly.
It seems like the code freezes in thread_2

Somebody can help me?
Thank you very much.

What hardware are you using?

As a general comment, threading is quite demanding on a microcontroller. Where possible it is much better to use uasyncio. See also tutorial. It is much more lightweight and also more highly developed.

Thanks for your response.

Mmmmm... nope. In my ESP32 (with latest micropytyhon 1.19.1: https://www.micropython.org/download/esp32/).

Using Visual Studio Code (latest version) and Pymkr extension (in order to comunicate to it) occurs an exeption error indicating that asyncio module doesn't exist nor uasyncio...

Is that normal?

Thank you

That would be the wrong version for an ESP32-S2-WROOM. This would be closer to the right image: ESP32-S2

Thanks for your response.

Mmmm....
I've been programming for one year (more or less correctly, without lots of errors :)
May be I'm doing my program with an incorrect micropython version?
I'm using an ESP-32 development board v1 (https://grobotronics.com/esp32-development-board-devkit-v1.html?sl=en) and ESP32 generic micropython (https://www.micropython.org/download/esp32/).

Ok! This night (Spain time) I'll try to change the micropython version for this: https://www.micropython.org/download/GENERIC_S2/.

Thank you very much.

Hello again.

Doesn't work. I've needed to (--force) installation of "GENERIC_S2" micropython and the board has come into infinite bucle error.
So I erased the board again.
The board chip is exactly: "ESP32-WROOM-32"

Any ideas?

Thank you very much.

You said it was an S2 in your earlier response. It is not an S2.

Threads are a great way to run out of memory. Best not to use them on MicroPython
