Project Information¶

Goals¶

The goal of the libdeco-ostc project is to provide dive decompression library reusing and integrating existing solutions if possible.

Implementation of dive planning library is _not_ one of the goals of this project.

Features¶

The libdeco-ostc project features are as follows

Buhlmann ZH-L16C with Gradient Factors algorithm used by OSTC dive computer (max. depth 130m)
OC and CCR modes
Nitrox and Trimix supported (up to 5 gases)
configurable dive altitude and surface pressure
configurable depth of last decompression stop
NDL calculation for non-decompression dives
C API
Python API
supported x86, x86-64, PowerPC and ARM platforms

Measure Units¶

The libdeco-ostc uses the following measure units

depth in meters, i.e. 30 meters
altitude in meters, i.e. 700 meters
deco stops or NDL times in minutes, i.e. 5 minutes
ppO2 in bars, i.e. 1.4 bar
surface pressure in millibars, i.e. 1013 millibar
