2014-11-04Prepare for PSCR calculationsGravatar Robert C. Helling
Calculations for passive semi-closed rebreathers are pretty much like OC except the pO2 is lower bey a certain (SAC dependent) factor. This patch introduces the corresponding calculations in case dctype == PSCR which is so far never set and there is currently no UI for these calculations. As pO2 is SAC dependent it takes a certain attempt at getting it and drops to defaults from the prefs otherwise. As there is no UI at this point and I also don't have any dives, this has not received much testing, yet, but it compiles. At least. Signed-off-by: Robert C.

2014-11-03Calculate nitrogen and helium gas pressures for CCR after import from CSVGravatar willem ferguson
Currently the gas pressures stored in structures of pressure are calculated using the gasmix composition of the currently selected cylinder. But with CCR dives the default cylinder is the oxygen cylinder (here, index 0). However, the gas pressures need to be calculated using gasmix data from cylinder 1 (the diluent cylinder). This patch allows setting the appropriate cylinder for calculating the values in the structures of pressure. It also allows for correctly calculating gas pressures for any open circuit cylinders (e.g. bailout) that a CCR diver may use. This is performed as follows: 1) In dive.h create an enum variable {oxygen, diluent, bailout} 2) Within the definition of cylinder_t, add a member: cylinder_use_type This stores an enum variable, one of the above. 3) In file.c where the Poseidon CSV data are read in, assign the appropriate enum values to each of the cylinders. 4) Within the definition of structure dive, add two members: int oxygen_cylinder_index int diluent_cylinder_index This will keep the indices of the two main CCR cylinders. 5) In dive.c create a function get_cylinder_use(). This scans the cylinders for that dive, looking for a cylinder that has a particular cylinder_use_type and returns that cylinder index. 6) In dive.c create a function fixup_cylinder_use() that stores the indices of the oxygen and diluent cylinders in the variables dive->oxygen_cylinder_index and dive->diluent_cylinder_index, making use of the function in 4) above. 7) In profile.c, modify function calculate_gas_information_new() to use the above functions for CCR dives to find the oxygen and diluent cylinders and to calculate partail gas pressures based on the diluent cylinder gas mix. This results in the correct calculation of gas partial pressures in the case of CCR dives, displaying the correct partial pressure graphs in the dive profile widget.

2014-11-01Remove code that zeroes out duplicate oxygen sensor and temperature valuesGravatar willem ferguson
Remove the code that changes all duplicate oxygen sensor, setpoint and temperature values from a dive log to zero. One of the motivations is that a zero setpoint value indicates an Open Circuit dive segment, not Closed Circuit Rebreather. The code in dive.c is removed and the comments for the corresponding restoration code that restores the last known values into sensor or temperature with zero values is [fill_o2_values() in profile.c] is changed to apply to the present situation.

2014-11-01Remove code causing problems with CCR dive log rendering.Gravatar willem ferguson
Currently, if there is a po2 given in the dive log, the dive is assumed to be CCR. When a CCR dive has a fo2 of 100%, then the po2 is set as the same as ambient pressure. This destroys the CCR po2 graph in the dive profile that derives from oxygen with a fo2 of 100% in one of the cylinders but which, after adding the dilent gas, has a po2 far below ambient pressure. The calculation for 100% oxygen only applies to deco using 100% o2 and then the dive computer calculates the appropriate po2. This patch removes the setting of po2 to ambient when fo2 is 100%, 1) to enable accurate graphing of po2 values for CCR dives using 100% o2 in the first cylinder. 2) To use the po2 value reported by the DC in the first place.

2014-10-28Improve tank handling for CobaltGravatar Dirk Hohndel
This isn't Cobalt specific, this is specific to dive computers that indicate the first tank that's in use with a gaschange event that coincides with the first sample. We need to make sure that we suppress showing that gas change event (regardless which cylinder it goes to) and instead set the correct cylinder index from the very start of the dive. This works with the test data I have and doesn't seem to break thing with any of the files that I tried... but I'm worried that this is not the right way to do things.

2014-10-27Do not zero setpoint value when duplicateGravatar Miika Turkia

2014-10-19Make planner work again for CCR divesGravatar Robert C. Helling
The latest CCR patches had rendered the planner not usable for CCR dives. This patch corrects this (and reenables the CCR set point column for segments). The problem was that a new member setpoint of struct divepoint had been introduced, but there was already po2 which had the same meaning. This patch merges the two and renames them setpoint to prevent future confusion. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2014-10-13CCR patch: Reorganise the oxygen partial pressure calculationsGravatar willem ferguson
This patch responds to the side effects that the CCR code has had with respect to ceilings in OC dives and dive plans. Dive ceilings are now calculated correctly again. The following were performed: 1) remove the oxygen sensor and setpoint fields from the gas_pressures structure. 2) Re-insert setpoint and oxygen sensor fields in the plot_data structure. 3) Remove the algorithm that reads the o2 sensor data and calculates the pressures.po2 value from function fill_pressures() in dive.c and save it as a separate function calc_ccr_po2() in profile.c. 4) Activate calc_ccr_po2 from function fill_pressures() in profile.c. 5) Move the relative position of the call to fill_pressures() within the function create_polt_info_new() in profile.c.

2014-10-12CCR patch: Calculate the correct partial gas pressures for CCR divesGravatar willem ferguson
This patch adds code to the function fillpressures() in dive.c to allow calculating o2 pressures, based on the data from the po2 sensors in the system. The following changes were made: 1) add code to perform po2 calculations for CCR with 1, 2 or 3 oxygen sesnors. 2) Add four fields to the gas_pressures structure in dive.h. This allows communication of data between the function that calls get_pressures() and the return of partail pressure values to the calling function. 3) Delete the fields for setpoint and gas partial pressures from the structure plot_info. All partial pressures (from instruments as well as calculated) now reside in the pressures structure that forms part of plot_info. 4) Perform changes in several parts of profile.c to make use of the pressures structure in plot_info.

Instead of trying to use add_event() to reinsert events we simply copy the memory and adjust the pointers. Using add_event() lost the gas mix and gas index information on gaschange events - and this prevent switches between cylinders with the same gasmix to be rendered correctly.

2014-10-12CCR patch: Oxygen partial pressuresGravatar willem ferguson
This patch does three things: 1) A new function fill_o2_values() is added to profile.c. This fills all oxygen sesnsor and setpoint values that have been zeroed before in order to save space in the dive log. This recreates the full set of sensor values obtained from the original CCR xml log file. 2) Function fill_o2_values() is activated in function create_ plot_info_new() in profile.c 3) The calling parameters to function fill_pressures() in dive.c are changed. The last parameter is now a pointer to a structure of divecomputer. This will be needed in the last patch of the present series of three patches.

2014-08-14Add "download into private trip" dialog checkmarkGravatar Linus Torvalds
This adds a checkbox for the divecomputer download dialog that allows you to tell the download to put the newly downloaded dives into a trip of their own. That in turn will disable the dive merging with any existing dives, which means that you will not mix up your newly downloaded dives with any old dives. That, in turn, is very convenient of you know that some of the dives were done by other divers (or from testing that happened during servicing etc), or the dive dates etc were wrong because the dive computer date had reset due to battery changes etc. Once you have all the dives in a private trip of their own, you can then fix them up (delete dives you don't want to merge etc), and then after all the data is ok you might want to merge the cleaned-up results with previous trips etc, and then manually ask subsurface to merge the dives or whatever.

2014-08-13Make SAC values in planner settings respect unit settingsGravatar Robert C. Helling
So far, the fields for the two SAC rates did not show a unit and were implictly l/min. Now they respect the settings for volume units. This was harder than I thought for two reasons: 1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point the field prefix and what is entered is actually hundreth of cuft per minute. 2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min internally) which would then become 19l/min when switching back. While being at it, I gave the gradient factors '%'-signs as units. Signed-off-by: Robert C. Helling <helling@atdotde.de> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-08-06Make gas use statistics be coherent and more completeGravatar Linus Torvalds
The gas use logic in the dive statistics page is confused. The SAC case had a special case for "unknown", but only for the first gas. Other gases had the normal empty case. Also, the logic was really odd - if you had gases that weren't used (or pressures not known) intermixed with gases you *did* have pressure for, the statistics got really confused. The list of gases showed all gases that we know about during the dive, but then the gas use and SAC-rate lists wouldn't necessarily match, because the loops that computed those stopped after the first gas that didn't have any pressure change. To make things worse, the first cylinder was special-cased again, so it all lined up for the single-cylinder case. This makes all the cylinders act the same way, leaving unknown gas use (and thus SAC) just empty for that gas. It also fixes the SAC calculation case where we don't have real samples, and the profile is a fake profile - possibly with gas changes in between the fake points. We now make the SAC calculations match what we show - which is admittedly not at all necessarily what the dive was, but at least we're consistent.

2014-08-05Picture handling: cleaning up the messGravatar Dirk Hohndel
We had pointers to data structures on the stack which we frequently reallocated. These data structure contain basically a filename and an offset. We then create a hash of the pointers to those datastructures with the filename being the key. And then we passed those pointers around through a Qt model(!!!) only in order to then later look up by filename what the offset might be. I am at a loss for words for the lunacy behind this design.

2014-07-12Rename event: correctly replace event with new oneGravatar Dirk Hohndel
I don't like that the event structure includes the variable length array. That really makes it a pain to change the name of an event (on the flip side, freeing events is easier I guess). Anyway, to correctly rename an event we need to actually remove the event from the correct dc and then add a new event with the new name. The previous code was insane (it only worked if the new name was of smaller or equal length, otherwise it had a beautiful buffer overflow). And of course we need to do this both for the current_dive and the displayed_dive. Fixes #616 Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
