Hello.

I want to build a speedometer with a 7 segment display. I want to use the GPS macro for this. What should I set in the GPS settings? How and which macro component should I use to read the speed value in km/h from the GPS?

I guess it's not that simple. I have attached a file.

Thank you very much.

Hello.

Does "ReadGroundSpeed" in the macro return that international nautical mile? (nmi)
I converted the value to km/h.

Thank you.

Raw GPS data returns ground speed in knots (nautical miles per hour) and so I assume the figure returned is in those original units.

Hi

This might be of help.

Hello,

Looks like your program should be about right. If it's not working then maybe check the baud rate of the GPS is correct and that the GPS is in a place where it can get a signal.
