libdivecomputer and Mares Nemo Sport
by Thorsten Peter 30 Mar '12

30 Mar '12

Hi guys, I tried to get my Mares Nemo Sport (in combination with the Mares Nemo Sport interface) working using libdivecomputer. Unfortunately I wasn't able to do so. I have to say that I was able to extract the data from the computer using Windows and the corresponding Mares tool - so the hardware should be working fine. I'm using Ubuntu 10.04 LTS - Lucid Lynx. I've tried with the newest GIT version, as well as with the latest snapshot from the website. The logs which I have attached were recorded with the latest snapshot (in the revision file it says 55a0a3fe0fff5b4b766003a5f09fce027b88572c) Then I saw on the website that you are looking for any data concerning the Mares dive computers - and here it is: EDY.log: command line call was ./edy /dev/ttyUSB0 output.log: command line call was ./universal -b edy /dev/ttyUSB0 output_dParam.log: command line call was ./universal -b edy -d xmlout.xml /dev/ttyUSB0 The xmlout.xml file during the last call was empty. Obviously the Nemo Sport computer switches back to normal mode (you have to set it into PC mode before connecting) if a test runs a long time - this is why there is no more data in the log files. If you need any more data I'm ready to support. Best regards Thorsten

Mares Nemo Excel - Nitrox bug?
by Björn Spruck 29 Mar '12

29 Mar '12

Hi, Strange behaviour for Nemo Excel. If I readout my dives, they are set to Nitrox 32 while the internal Logbook shows them as AIR (which they actually were!). My guess: there is an additional AIR/EAN flag. Tschau, Bjoern

Mares M1 data format
by Björn Spruck 27 Mar '12

27 Mar '12

Hi, I reverse engineered a bit the M1 data format and would like to add events like "deco", "slow warning" etc in the data stream. Actually the format is similar to other mares computers (nemo), just shifted a bit. How do I submit patches? Tschau, Björn

ProPlus 2.1 Temperature Values
by Sam Calhoun 01 Mar '12

01 Mar '12

Hi, Just writing to say that after using libdivecomputer in my program and testing it with a few different devices, I have found one small bug. The ProPlus 2.1 (the version with metal buttons) did not parse temperature values correctly. Here's the small change to "oceanic_atom2_parser.c" that fixed the issue for me (relative to the latest snapshot on the download page): --- oceanic_atom2_parser.c-revBASE.svn000.tmp.c Wed Feb 29 23:08:42 2012 UTC +++ oceanic_atom2_parser.c Mon Feb 6 23:48:19 2012 UTC @@ -37,6 +37,7 @@ #define VEO20 0x4359 #define VEO30 0x435A #define ZENAIR 0x4442 +#define PROPLUS21 0x4444 #define GEO20 0x4446 #define OC1B 0x4449 @@ -329,7 +330,7 @@ temperature = data[offset + 3]; } else { unsigned int sign; - if (parser->model == ATOM2) + if (parser->model == ATOM2 || parser->model == PROPLUS21) sign = (data[offset + 0] & 0x80) >> 7; else sign = (~data[offset + 0] & 0x80) >> 7; Thanks, Sam
