  • How to get comport number by just passing VID and PID

    Hi,
    I am using the uLCD 28PTU and it has the Silicon Labs CP210x USB to UART convertor. I can figure out the com port number by just looking at the device manager page, but if I connect another LCD there is new COMx number for it.

    Is there any code or function to directly get the comport number by passsing VID and PID as arguments. The VID and PID are available in the datasheet of CP210x.

    Thanks for help

    Regards,
    Rohit

    You can work out the com port number from looking in the registry.

    Unfortunately the details are beyond the support provided on this forum.

    You should be able to find the answer on stackexchange and the like
