OCC GPS for myRIO Project

You can use the OCC GPS for myRIO Project as a starting point for creating myRIO applications that acquire GPS data using the OCC GPS for myRIO hardware module. Other GPS's may be compatible with this code as well, but are not specifically addressed here.

This program uses a Flat Sequence structure that executes frames from left to right.

The Flat Sequence structure in this template executes the following frames from left to right:

1. Initialize—Initializes the myRIO serial port.
2. Acquire and process data—Acquires data from the OCC GPS for myRIO and processes the data for presentation. The While Loop repeats code until you click Stop or an error occurs.
3. Close—Closes user interface elements and the serial port, and resets the myRIO output values to zero before the application exits. Closing code is optional.

1. In the Project Explorer window, navigate to your myRIO target and open the Main VI.
2. Click Run. This application acquires GPS data from the OCC GPS for myRIO hardware module and displays it. If the GPS cannot acquire a lock from the satellites, the GPS data may not be valid.
   
3. Click Stop to stop the application.

The GPS sends out several different data strings by default, and can send several others if it is configured properly. This example program demonstrates how to parse just one string. Refer to the GPS chip documentation for information on the other strings available. Parsing each string can be accomplished in a manner similar to the code provided in the example, by referring to the documentation.
