#9: Add support for temperature and tank pressure on Mares Nemo Air -------------------------------------+------------------------------------- Reporter: bbremer | Owner: Type: enhancement | jefdriesen Priority: major | Status: Version: 0.4 | closed Keywords: | Component: | Dive parsing | Resolution: | duplicate | Plattform (please give specifics in | the ticket text): All -------------------------------------+------------------------------------- \ \ \ \ Changes (by jefdriesen): * status: new => closed * resolution: => duplicate \ \ \ Comment: As far as I know, the Nemo Air doesn't record pressure per sample. I suspect the data in the uddf file is interpolated from the begin/end values. Now, regarding these begin/end values for temperature and tank pressure, the libdivecomputer api currently doesn't support those. That's already on the todo list. See tickets #3 and #4. So I'll close this ticket as a duplicate.

I forgot that the Nemo Air uses 5 bytes per sample instead of 2. Those extra 3 bytes may indeed contain tank pressure data. Initial investigation shows that one of those bytes contains the gas consumption (in l/min) for each sample. That's most likely the value used to plot the graph you attached. So far I have not been able to find the tank pressure per sample, only the begin/end values. I could find the values corresponding to the <tankpressure> elements in the uddf. But if I treat those as delta values, then the pressure drops too fast, and I end up with negative pressures. That's certainly not correct. \ \ \ -- Ticket URL: <http://trac.libdivecomputer.org/ticket/9#comment:3> libdivecomputer <www.libdivecomputer.org> a cross-platform and open source library for communication with dive computers from various manufacturers
