Subgravity H3?
by William Perry 22 Mar '15

22 Mar '15

A fried of mine has a couple of these to play with and is raving about them as technical / caving computer - wondering if anyone has looked at adding support for downloading to libdivecomputer? One of its big features is downloading over NFC to android devices, but it can also download over USB. I might have a chance to borrow a unit to play with once I get back from Cozumel. Not much of a USB sniffer guy, but I can try to throw it onto a linux VM and see what kind of interfaces it exposes, etc. Hopefully it just exposes info on a filesystem. -bill

Reparsing data
by Shawn Willden 18 Mar '15

18 Mar '15

Is there a convenient way (short of figuring out the API and writing a program... which I can do but I'd rather not) to parse a dump file? I have managed to download from my old Uwatec Aladin Air Z, and most everything is good but I'm not getting gas consumption data. Looking at uwatec_memomouse_parser.c, it seems like the parser should be getting tank pressure from the data, but I'm not seeing it in subsurface. So, I'd like to reparse a dump file so I can walk through it in the debugger and figure out what's going on. I looked at hacking up examples/universal.c, but it's pretty set on downloading from a computer. Also if anyone knows of any documentation for the Uwatec data format, that might be helpful, but I suspect I can get a really good idea of what's going on by just walking through the code as it dissects the data. -- Shawn

Question about Suunto EON Steel on MacOS
by Janice McLaughlin 09 Mar '15

09 Mar '15

I was just looking at the Suunto Eon Steel support added and was wondering if anyone had tried it on a Mac. Specifically: Since the EON appears to identify as a USB HID device, the oh so wonderful MacOS kernel driver will probably grab it right? Which means in suunto_eonsteel_device_open(), the call to libusb_claim_interface(eon->handle, 0) will fail. (Been there, done that). But there is no return code checking on the call so the open will continue. Is that on purpose? Or by accident? And there is no corresponding call to libusb_release_interface() in close either .... It's obviously working fine on Linux and Windows, but I can't see how it would work on a Mac unless I'm misinterpreting what the device actually looks like from a USB point of view. I don't have one to test with but wanted to look into adding support for it. I dug around Suunto DM5 and, at least on the Mac, it seems to be using hidapi although again, since I don't actually have one in my hands ....
