Currently Subsurface only explicitly accommodates the Poseidon MKVI and
the APD Inspiration family of rebreathers, having two/three oxygen
sensors by default. The reason is simply: these are the equipment mostly
used by local divers here. Since rebreathers often download only one
dive at a time (one dive = one complete dive log file), a normal dive
list-oriented download is not relevant. There is not the equivalent of a
libdivecomputer for these CCR uploads and we import the MKVI and APD
dives through the text file import mechanism. Currently, several third
party manufacturers use Shearwater equipment as the controllers for CCR
equipment (e.g. Hollis Prism). The addition of Shearwater-generated CCR
imports will be the next quantum step for making Subsurface accessible
to CCR divers. There are some problems with respect to the import of CCR
dives:
1) Since there is not the equivalent of a libdivecomputer, we are
dependent on doing the inital download from CCR to text file using
proprietary software that comes with the equipment (mostly Win-only).
Extremely inconvenient. Then import from text to Subsurface.
2) I do not know how many Subsurface users actually log CCR dives. I
know of four users in our country. Clearly a pretty small user base.
There has been no correspondence from CCR divers on the mail list, so we
do not know in which ways to improve the existing code.
There is a possibility that the extension to Shearwater may be very
simple, depending on whether Jeff includes sensor data in
libdivecomputer, otherwise it may be a bit more complex.
Kind regards,
willem
