Work for the 0.94 release is coming along. Most of the main work has been completed: (a) porting emulator to Linux, to support both FreeBSD & Linux; (b) porting firmware to GPS Logger V2.4, to support both V1.0 and V2.4; (c) supporting generic and binary compression for output data; (d) PC based application testing for both V1.0 and V2.4. There are also a bunch of smaller scale additions and modifications that I won't go into here right now.
All I have to complete now are some performance cleanups (some code inlining thanks to a gprof analysis), some emulator cleanups (clean termination at end of input files) and a round of testing. The testing can't be understated: I need to (a) test code against GPS sample data, (b) produce compression statistics from same data, (c) test power consumption for this and original firmwares, (d) general code review and functional testing.
I have also decided on the roadmap for future releases: the next one, a 0.96, will focus exclusively on reworking and extending the GPS data handling, by (a) the logger programming the GPS module for specific sentence, powersave and other features; (b) support sparkfun V2.4 firmware features (hold off, etc); (c) customisable filenames with date/timestamps; (d) a separate utility tool for conversion from raw/nmea to kml/csv with binary/text encoding and using compression; (e) power/performance improvements as necessary. Beyond that, a 0.98 release will be entirely dedicated to power/performance optimisations and improvements, and additional debug/inteface features (e.g. I may add in an xmodem download feature (so you can extract logs without having to remove the SD card). After 0.98 comes 1.00, when all should be stable, working and optimal.
I hope to have a 0.94 release ready in the next 3-4 weeks. Let me know now if there's anything you're interested in.
