Galileo Sol dive log decoding for sidemount dives.

[Willem Ferguson]

Hi Jef,

Attached is my modification of Simon's code for decoding Uwatec dive 
logs. For your convenience I also attach a dive log. If you look around 
line 388, there is decoding of bookmarks. If you look at lines 390-440 
there is decoding of cylinder changes. The Uwatec Sol registers cylinder 
changes even if the gases are identical. I use the hex value f9x value 
to detect a cylinder change. I also managed to decode a number of alarm 
conditions such as max depth exceeded, rapid ascent, heavy workload, etc 
but I did not spend a lot of time on that, though these are reflected in 
my modifications to the code.

I  must admit that I am focused on my own need which is to record 
sidemount dives accurately, preferably using cylinder change events, 
otherwise using bookmarks. Is any of this reasonably easily 
implementable within the context of libdivecomputer-subsurface dive 
upload? What does libdivecomputer do if there are two successive 
gas-change events to the same gas? I get identical information if I 
write the data on a slate during the dive and decode the hex dump 
afterwards. At the moment I download each dive twice, once into the 
Subsurface dive list and then into a hex dump (also using Subsurface). 
Then I run the above software on the hex dump which gives me the times 
at which I performed cylinder changes. A roundabout way and not 
efficient at all, but it works if one is prepared to take the trouble.

What would you suggest I do in order to make a positive contribution? I 
would be glad to help in any way.

Kind regards,
willem
