    Good morning, sorry for my poor English, I’m French !

    All is in the title.

    I use Controllino Maxi linked with Raspberry Pi3 by USB.

    I use Pi with touchscreen for MMI (IHM in french). When I shutdown the Pi, the Controllino make reset and I try to understand how and why.

    As I read in the User manuel :

    The main function of the USB port is to program the CONTROLLINO. Inside the CONTROLLINO there is a USB to UART converter which generates a virtual COM-Port on the PC. You can also use this port to give data to a terminal or another program.”


    Maybe this USB to UART converter make a DTR signal when the USB link is closed…



    Tanks a lot by advance.

    Xavier.
