Connecting a gps receiver to a microcontroller is not a big deal. Most commonly the gps receiver sends its data, packed into NMEA format, as a serial stream over a serial port. But what to do with this data? For tracking purposes its just enough to save the datastream to a nonvolatile memory. But if you want to visualize the gps data on your device, for example show your actual position on a map you are facing two problems:
-
You have to deal with a big amount of map data.
-
The map data underlies restrictive copyright licenses.
OSM4Primer2 overcomes with this problems.
-
Map data can be stored and recovered from the micro-sd card.
-
Map data is derived from the OpenStreetMap project and only underlies the Creative Common Attribution-Share Alike license
This is how map is displayed on lcd screen
So all you have to do is download the desired map data from OSM project and save it to the micro-sd card. OSM4Primer2 extracts the actual geografical position out of the NMEA datastream and correlates it to map data on the micro-sd card. As a result the position is shown on the map.
