Currently the profile ringbuffer starts at the base address 0x4000, but I believe the real start is one 0x20 byte page earlier, at 0x3FE0. I have two reasons for this: 1. To locate the start of a dive, we always have to substract one page from the pointers in the logbook ringbuffer. With the new base address, they would point directly to the start of the dive, which makes a lot more sense. 2. When comparing the divetime as stored in the header with the one obtained by counting the number of samples, they always match except for dives that span the ringbuffer wrap point. If those extra 0x20 bytes are included, the counts do match again. Unfortunately, this change breaks the assumption that the ringbuffer is aligned to packet boundaries. As a workaround, we define a virtual ringbuffer that is slightly larger than the actual ringbuffer, but properly aligned. Data outside the real ringbuffer is downloaded and then immediately dropped.
Overview ======== Libdivecomputer is a cross-platform and open source library for communication with dive computers from various manufacturers. The official web site is: http://www.libdivecomputer.org/ The sourceforge project page is: http://sourceforge.net/projects/libdivecomputer/ Installation ============ On UNIX-like systems (including Linux, Mac OS X, MinGW), use the autotools based build system. Run the following commands from the top directory (containing this file) to configure, build and install the library and utilities: $ ./configure $ make $ make install If you downloaded the libdivecomputer source code directly from the git source code repository, then you need to create the configure script as the first step: $ autoreconf --install To uninstall libdivecomputer again, run: $ make uninstall Support ======= Please send bug reports, feedback or questions to the mailing list: http://libdivecomputer.org/cgi-bin/mailman/listinfo/devel or contact me directly: jef@libdivecomputer.org License ======= Libdivecomputer is free software, released under the terms of the GNU Lesser General Public License (LGPL).
