Sven, The recall of square is just for serial numbers end with 003. I have 006 in mine. "Aladin" is because of the next generation of scubapro uwatec divecomputer with big caracters... http://www.scubapro.com/en-US/USA/instruments/computers/products/aladin-squ… Vincent (Vavincavent)

Hi all, I have 2 dive computers. * Aladin pro, with it, temperature is not supported yet by libdivecomputer (just one data in the header). * Aladin square, it's not supported by libdivecomputer yet. Before discuss about calculus, age of captain, etc... Is it not more important that libdivecomputer just transfer basics data and support the more divecomputer as possible? Vavincavent

Is it possible now to have temperature from uwatec Aladin pro? Vavincavent

[PATCH] Unsigned int type can't be below zero

Still having issues with a Pro Plus 2

I'm not sure this issue was ever fixed: http://libdivecomputer.org/pipermail/devel/2012-January/000039.html I managed to go diving again this past weekend :) I renamed the old subsurface.ml file and now see this error in the log: INFO: Write: size=6, data=3401A901AC00 INFO: Read: size=1, data=5A INFO: Read: size=68, data=B007FE0617001400288321483500001645005000099F004BC00040001186004BC0E5004000137E004CC0004010147B004CC0C80140001332004CA0014000132D004C90CF INFO: Write: size=6, data=3401A501A800 INFO: Read: size=1, data=5A INFO: Read: size=68, data=2770000E12004D302770100C15004D40892770400910004D3000000000000000006D5E50051E4D56F10BBADCFE002143658754251FDC219F1B1413840D6C0B040A5B089B ERROR: Unexpected number of samples with the same timestamp.

Programming questions
by John Van Ostrand 07 Jul '14

07 Jul '14

Hi, I've started writing libdivecomputer code for the Cochran and I have a few questions that I expect are easy answers. 1. I'm wondering how much I should read in the _init function. It seems I should read enough to verify I'm talking to the right device and get the serial number. Is that right? 2. There are other reads I can do that will get things like # of dives, gas mixtures, conservatism, etc. I need number of dives to read the log book. Should I do this in _read? And does it make sense to do this read before setting progress information? 3. I have extra information that I can offer the user, pre- and post-dive things like battery voltage, tissue load, time to fly, previous SIT, repetitive dive count and dive profiles samples like tissue load every 24 seconds, NDL remaining (I think), deco required (I think), ascent rate. I can also get post dive off-gassing tissue load and temperature samples. The DC continues to log samples until off-gassed I can't see any structure for all of this, or a way to carry around that kind of data. 4. The DC requires some prodding to accept commands, after being prompted it emits a byte every second. Initially it's a 0xAA but after reading dive samples it's a 0x00. The only way I've been able to prompt it is to send a byte to it. The vendor software doesn't do this. Could it be a USB signal of some sort. I see "Sync Reset Pipe and Clear Stall" in the USB capture and "Vendor Device" and "Control transfer". Any ideas on what I might try? -- John Van Ostrand At large on sabbatical

Help needed decoding data
by John Van Ostrand 03 Jul '14

03 Jul '14

Hi All, I've been staring at and playing with this data for a week now and I don't feel any closer to deciphering the dive profile sample data from my Cochran EMC-20H. Personally I love a challenge like this and I'm hoping some of you do as well because this one is tough. Instead of digging into a good book this weekend why not sit back with a laptop or tablet and this puzzle. You'll find everything you need at the link below. I've removed the mundanely easy work from this puzzle. Included are binary files, annotated hexdumps to illustrate the data and some programs to extract and display data (don't judge, these are quick and dirty programs.) Start with the README and you'll be into the fun part within minutes. https://drive.google.com/file/d/0B-VD5cn7zgGHN1pVRWpib2pJc0k/edit?usp=shari… -- John Van Ostrand At large on sabbatical

[Patch] Added --with-examples option to configure
by Venkatesh Shukla 30 Jun '14

30 Jun '14

Example scripts may not be needed always. It might be a helpful option to disable its compilation. Added option of disabling using --with-examples=no option in for autoconf. Please find the attached patch. Regards -- *Venkatesh Shukla*
