With an other pins it works,

But the switch callback

# USR Schalter
print ('INIT des Schalters')
switch = pyb.Switch()

def switchcallback():
    print('INFO-Switch: Switch Callback aufgerufen!')

switch.callback(lambda :switchcallback())

only starts one time.

Which is the best solution to stop the scheduler with a push button (the USR or an hardware interrupt (a button I can braze on other pins)
(and restart it)

You can pass switchcallback directly to the callback function.

What you coded:

Code: Select all

switch.callback(lambda :switchcallback())

is equivalent to:

Code: Select all

x = switchcallback()
switch.callback(lamba: x)

You can code it like this:

Code: Select all

switch.callback(switchcallback)

Note that there are no parenthesis so it passes in the address of the function whereas with the parenthesis it calls the function.
