CCS/CC430F5137: Creating a local database to store GPS information and reading the same using CC430F5137

Can you be more clear? Were do you want to store the "database" ? Do you just need to store a single location in non-volatile storage? If not, how many locations do you need to store?

Hi Keith,

Thank you for your reply. The database must be such that it must be retrievable from within the code for the system to compare the latitude - longitude values received from the GPS, against the values in the database.

Yes I would want it to be a non-volatile storage since it is a static data.Also storing around 15 locations would be sufficient.

Thanks and regards,

When you have fifteen predetermined locations, you could just store them in an array:

struct location {
    float lon;
    float lat;
    const char *name;
};

static const struct location locations[15] = {
    { .lon = 12.345, .lat = 34.567, .name = "here"  },
    { .lon = 23.456, .lat = 45.678, .name = "there" },
    ...
};

Why are you calling it "database"? Do you need to do anything special with the data? Do you need any operation except searching for the nearest location? Is there any reason such a constant array would not work?

Hi,

Thank you very much.Initial assignment was to include location coordinates of at least 30 locations.Hence to shorten the code length I felt a dedicated storage would be better.

I will incorporate your logic for 15 locations and try the output.

Thanks and regards,
