RaspberryPi Davis Pro 2 USB Port
My Pi doesnt have a serial port. I have USB ports. How do I configure this to work with the USB?

Re: RaspberryPi Davis Pro 2 USB Port
This is mentioned in the MX FAQ. When you plug in the station, a virtual serial port will be created. Do 'dmesg' to see what port has been attached to the cp210x adapter and specify the corresponding serial device in the MX config - it will normally be /dev/ttyUSB0

Re: RaspberryPi Davis Pro 2 USB Port
What do I actually enter then? /dev/ttyUSB0
or just part or that or what? I have tried that and USB0 by itself but not seeing any data displayed. Maybe I need to do something else first?

Re: RaspberryPi Davis Pro 2 USB Port
Typically, yes...but you need to make sure once plugged in. It may not always enumerate it to the first.
issue this command at a Pi shell prompt:
ls /dev/ttyUSB*
and see what it returns. After you plug it in of course.

Re: RaspberryPi Davis Pro 2 USB Port
Also, and just being clear, are you running a Linux distribution on your Pi? I know some are now using Win10 IOT on it. That won't work.

OK I see data on the datalog viewer so getting closer!
Dashboard - Now - Gauges do not seem to do anything but there is data in the data log
