dctool source code
by Darrell Pelan 03 Jan '17

Hi, I'm new to this group and greatly appreciative of your work. I was able to use dctool to download my dive computer data. Is the dctool source code available? I'd like to see the code as an example on how to use the libdivecomputer code. Thanks, Darrell

shearwater Perdix AI
by Jon Gross 01 Dec '16

01 Dec '16

I have in my greedy little hands a Shearwater Perdix AI computer, which Shearwater says shares the same firmware with the Perdix and the Petrel, but it will have air consumption (if equipped with a sender). Is there anything I can send a developer that would help with support or this? I didn't see it in the list of supported computers. Thanks! -jon

Problem reading Aladin Pro Ultra w/MemoMouse
by Garry Glendown 22 Sep '16

22 Sep '16

Hi, after some undesirable long diving hiatus I'm getting ready for a nice dive trip in October. In preparation, I started getting my tech stuff up to date. Not using my former XP Notebook, of course the old Datatrak software will (most likely - didn't try) not work on my current Win10 system. Browsing the web I came across the "Subsurface" program, which uses libdivecomputer. As my Notebook doesn't have a native serial port, I am using a USB-Serial adapter (which works fine for other serial connections, like Cisco routers and the likes). Subsurface also recognizes the port correctly, providing it in the Import window by default. I tried to use dctool, but somehow I can't put together the options to even access the serial port, or anything ("No device name or family type specified") - here's the command line I assumed: dctool -d COM6 -f Uwatec -m "Aladin Pro Ultra" download Any idea what I'm doing wrong?

[PATCH 3/3] Suunto EON Steel: extend our string space

29 Aug '16

From: Linus Torvalds <torvalds(a)linux-foundation.org> Date: Mon, 29 Aug 2016 15:03:02 -0700 Subject: [PATCH 3/3] Suunto EON Steel: extend our string space We only used to save 16 extended strings per dive from the EON Steel download, which is _plenty_: it's not like we actually generate that many strings. Firmware version, battery status, transmitter info - there's just not that many strings. Oops. Except if you have lots of transmitters. Then each wireless transmitter will have three strings each, for transmitter ID and beginning/ending battery status. I only have one, but Andreas Klein has four. And it took me embarrassingly long to realize that he really did have them on the dives, because after the first two transmitter IDs got recorded, the string space filled up and we silently dropped the rest. But I have learnt my lesson. Future generations will talk about how I said "32 strings will be enough for anybody". But at least it should be enough for a few more transmitters. Somebody should extend this some better way, but I'm still chasing other issues.

[PATCH 2/3] Suunto EON Steel: initialize the tank 'gasmix' index
by Linus Torvalds 29 Aug '16

From: Linus Torvalds <torvalds(a)linux-foundation.org> Date: Mon, 29 Aug 2016 15:03:02 -0700 Subject: [PATCH 2/3] Suunto EON Steel: initialize the tank 'gasmix' index The gasmix query interface considers cylinders and gas mixes independent things, so the tank data structure has a pointer to the gasmix index. But the EON Steel treats cylinders as just having a gasmix (and so does subsurface, for that matter), so the gasmix index for the tank is just the same as the tank index. But we never filled it in, so you'd always see a "gas index" of zero, and subsurface would end up warning each time about how the gasmix index doesn't match the cylinder index (but because subsurface actually agreed with EON Steel, it worked despite the warning).

[PATCH 0/3] Some EON Steel libdivecomputer fixups
by Linus Torvalds 29 Aug '16

29 Aug '16

So I've been looking at the EON Steel backend because Andreas Klein has a slightly more complex situation than the one I use, notably multiple wireless transmitters. That showed a few issues. The first patch actually predates all this work, and was just a cleanup from before. The two other patches are trivial fixes for trivial issues I've found so far. One causes an annoying and misleading warning in subsurface, and the other one results in the transmitter information not being saved if you have more than two wireless transmitters. The actual *big* problem is that subsurface itself doesn't handle the issue of multiple concurrent transmitters right. Most (all?) other dive computers just give the pressure for the currently selected cylinder, if they support multiple pressure sensors at all. But these are real cleanups/fixes regardless.
