This MATLAB® example shows you how to configure and control external hardware in MATLAB. Specifically, we show how to use MATLAB to communicate with a Garmin® handheld Global Positioning System (GPS) receiver with an RS-232 serial interface.
MATLAB supports serial devices including RS-232 using the Instrument Control Toolbox™. In the article, we describe how to use a graphical user interface called TMTool to locate, configure, and control the hardware without writing MATLAB script. We also show how to create drivers to incorporate lower level commands.
This MATLAB example is featured and explained in the May 2007 MATLAB Digest article called "Configuring and Controlling External Hardware in MATLAB" authored by Trent Jarvi of The MathWorks. This article is available at:

hello .. i'm working on this subject " Using MATLAB with External Hardware " ..
the files can't be downloaded !
can anybody do something .. cos i need it as soon as possible ..
y como haría para que este adquiriendo las lecturas en tiempo real, es decir, que siempre me este dando los datos en cualquier momento??????
Is there a simulink equivalent for reading and parsing NMEA strings from a Garmin or other GPS unit?
The good job.
I have made the same script, but using differen NMEA word and obtain information about time and velocity too.
The codes modifies strings looks like:
data = fscanf(obj1);
if (NS == 'S')|(NS == 's')
if (EW == 'W')|(EW == 'w')
And so one.
For displaying there is enough to show simply Latitude and Longitude with N or S, E or W, but to calculation better transfer coordinates.
The same is with time.
I know, that my code is not optimal, but it reads only required information.
i want to learn it
