Pi Pico: Thonny/CTRL-C with two threads

[ESPWarren]

I have searched for an answer to this but could not find other reference...

I am using a Pico W. It has code to do stuff in two threads. It works fine - I can see the output of print statements from both cores.

When I click CTRL-C, the first thread obviously stops. But the second one keeps going and no amount of CTRL-C clicking can stop it!

Any ideas?

Just to say, if I disconnect the board and CTRL-C quickly enough (before the second thread is launched) then there is no probem...)

You could use a shared global variable, say STOP = False. In the main thread, trap KeyboardInterrupt and set STOP = True. On the second core, periodically check the variable. In fact it might be worth trapping any exception and setting STOP = True:

STOP = False
try:
    run_my_application()
except:  # ctrl-c or program error
    STOP = True
