Beispiel für die Einbindung der MicroPython-Library Thread.py :

#
import _thread
#
class CThread():
  #
  def __init__(self, threadid, onexecute):
    self.ID = threadid
    self.OnExecute = onexecute
    self.IsBusy = False
    return
  #
  def Start(self):
    self.IsBusy = True
    _thread.start_new_thread(self.OnExecute, [self])
    return
  #
  def Abort(self):
    self.IsBusy = False
    return
  #

Wichtig: Die Library Thread.py muss im FileSystem des MicroControllers vorhanden sein!

Aufrufendes Programm Esp32CheckThreading.py :

#
import time
#
import Thread
#
#-----------------------------------------
def CBOnExecute(thread):
  print('CBOnExecute[{}]: begin'.format(thread.ID))
  I = 0
  while (thread.IsBusy):
    I += 1
    print("CBOnExecute[{}]: Hello({})!".format(thread.ID, I))
    time.sleep(1)
  print('CBOnExecute[{}]: end'.format(thread.ID))
#
#-----------------------------------------
if ('__main__' == __name__):
  print('*** Esp32CheckThreading: begin')
  T = Thread.CThread('T1', CBOnExecute)
  T.Start()
  time.sleep(5)
  T.Abort()
  time.sleep(5)
  print('*** Esp32CheckThreading: end')
#

Run-Ausgabe im Terminal:

>>> Running ..\Esp32Threading.py
>>>
>>> *** Esp32CheckThreading: begin
CBOnExecute[T1]: begin
CBOnExecute[T1]: Hello(1)!
CBOnExecute[T1]: Hello(2)!
CBOnExecute[T1]: Hello(3)!
CBOnExecute[T1]: Hello(4)!
CBOnExecute[T1]: Hello(5)!
CBOnExecute[T1]: end
*** Esp32CheckThreading: end
