Testing threading on micropython

threadTest.py

import machine
import utime
import _thread

def threadStart(x):
    while True:
        print(f"Thread {x} here!")
        utime.sleep(1)
        
_thread.start_new_thread(threadStart(1), ())
print("ayyy")
print("lmao")

my thread runs but the follow text/code does not, this is for the pico which has 2 cores and trying to get dual threads running

maybe due to repl being on one core?

seems it doesnt like having the functions args in like that, and even if one arg is being passed it must be in a tuple, example working below:

import machine
import utime
import _thread

def threadStart(x):
    print("\nyo")
    utime.sleep(2)
    print("ayy")
        
        
_thread.start_new_thread(threadStart, (1,))
print("hey")
utime.sleep(3)
print("gg")
