KeyboardInterrupt Exception not handled after pushing Ctrl-C



  • Version; MicroPython v1.8.6-251-g2fb950d on 2016-12-16; LoPy with ESP32

    The KeyboardInterrupt Exception is not handled as such, and not as another exception type.
    he follwoin small piece of code should catch Ctr-C, but it does. Other ports of MicroPython work properly, and even the WiPy 1 port does at least not terminate (it ignores Ctrl-C)

    import sys
    while (True):
        try:
            c=sys.stdin.read(1)
            sys.stdout.write(c)
        except KeyboardInterrupt:
            print("received keyboard interrupt")
        except:
            print("Got another interrupt")
        if c == "q":
            break
    


  • Thanks @Ralph. On WIpy 1 there is however a little inconvenience in that the keyboard interrupt is not flagged immediately, but only after another character is typed. This behavior exists since ever, I reported it but it was never fixed.
    Best regards, Robert



  • Hi @robert-hh,

    I tested it and this seems to be a bug in the firmware. I can't seem to catch the keyboardinterrupt. On the WiPy 1.0 it does work.

    I added this bug to Github issues now, you can find it here. If you find more specific bugs like this in the future, please post it there.

    Regards,
    Ralph
