Read GPS NMEA sentences #77

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What new or enhanced feature are you proposing?
 We could read NMEA sentences directly from a GPS device

What goal would this enhancement help you achieve?
 Currently we depend on GPSd to get locations, this will be an alternative.

see http://code.google.com/p/python-gpsd/ for more details

python-gpsd requires pySerial, all the sources are now added under folder pyGPSD
http://code.google.com/p/gmapcatcher/source/browse/#svn/trunk/src/pyGPSD

There are 2 working sample scripts: 
 - scan.py (shows the available ports) 
 - miniterm.py (reads from port & outputs to the console)

Now need to work with the NMEA toolkit to parse the NMEA sentences

it seems even the gpsd integration code may need an update, as – at least for 
me – no data is making it all the way to gmapcatcher, even though xgps – as 
modified at pyGPSD/gpsView.py – is working properly;

the patch contains some moves in the direction of importing the gpsView code to 
gps.py although *needs more work*

Reading NMEA -sentences straight from the serial port has it's ups and downs. 
The reading itself isn't hard, I've done it with Python and C multiple times.

Positives on changing to serial read:
- works on every device
- no need to keep track of different versions of GPSd
- easier to setup as everything would be done in GMapCatcher

Negatives
- GPSd does have drivers for multiple other devices, which don't send NMEA data 
or need some kind of initialization.
- serial port is reserved, no chance to have multiple programs with different 
views (such as compass, speedometer etc)

If someone else does the needed menu structures, I can look into the NMEA 
parsing etc.

Started working on this tonight, I currently have a working serial port reader, 
will test it more thoroughly tomorrow...
