  • Cannot find file specified opening com port

    what causes a red comm port? Gen4-uLCD-70D connected to Arduino MEGA. I downloaded a new program to the display via a micro SD from Workshop4 Visi Genie without issues a couple weeks ago, now I'm getting a "Red" Comm 6 error in file path and cannot 'build n load'. All help would be greatly appreciated.

    From your topic title it would mean that the com port doesn't exist. Are you sure it is plugged in and that you are using a proper USB cable (Some are Power only). Try the drop down to see if the Com port has moved. Then try Device manager to see what the status looks like in there.

    I don't understand "a "Red" Comm 6 error in file path".

    You mean the traffic light is RED underneath the com port name in the Comms Tab?

    If the status message says something like 'Error in file path', then this is unheard of for a Com device. If you get this check the com port in Device Manager
