GPS track with Labview

[shockst]

Hi everyone,

I would like to draw a track at Labview using latitude and longitude data that i'm receiving from a gps module.

I want to plot the graph in a graph. Anyone could help me to do that?

Best Regards,

Vitor Crepaldi.

Hi Vitor,

convert your "latitude and longitude data" to x/y coordinates to display them on a XY graph…

What is your exact problem?

I want to draw the track but I don't knw how.  

Something like this: https://www.youtube.com/watch?v=5A2R_ryAQPs.

I work in a project that we build an off-road car at the university. And we want to know the track that the car is doing. 

Could you help me?

Regards,

Vitor Crepaldi.

Why don't you download the code example that is at the link right under the You-Tube video?

It's actually pretty good example of parsing NMEA GPS sentences.

Most GPS's simply spit out a constant stream of NMEA "sentences"  on a serial port at 9600 baud 8N1 it would be pretty simple to modify the example to use live data to produce a live plot.

Here is a good link on decoding NMEA GPS sentences http://www.gpsinformation.org/dale/nmea.htm

There is a way to hold th last received number at the array?

I can increment the index of the array, but the last one number turns to zero, but I want that he staus in that position.

I tried to search something like that but i didn't find.

I attached a photo abou my code. 

Regards,

Vitor.

I don't understand what you are trying to do and how it pertains to your original question.

Try attaching your VI instead of a screen capture so I can suggest changes without having to redraw your block diagram

I will receive tha latitude and longitude data by the serial port.

If I put each data in a array I will can draw the track. But I need that each data will appear in a different column of the array, but keeping the hystory.

In my code, I receive each data, but I only see the new number. The last number turns to zero.

I attached my code to you see.

Regards.
