open source decompression tables.

dangraf · 22nd June 2008, 20:53

I'm building my own dive computer for a CCR (not for commersial use) and are in need of decompression tables/algorithms to make it complete.

I'm searching for info about decompression tables and have been looking at the VPM which is an excell sheet and macros in basic. I have also been looking at the "open source code dive computer" where the code are written in asm for a PIC microcontroller. I have also been looking at "v-planner live" which seems to consume a lot of program-memmory and need a 32bit floatingpoint controller.

I'm writing my code in C on a 16bit microcontoller with limited programmemmory (255k).

Do you have any recomendations where to understand decompression therory so I konw what I'm doing? I have ofcause some theories about what's happening, but I want to be exact.

Are there any other open source decompression tables/algorithms that are availible and maybe already written in C?

Or do you have any other recomendations to help me out?

I found this site very helpful DIY DECOMPRESSION and Stuart is a member of this forum so you may get some direct answers if you talk nice

checkout MV-Plan and associated source code. It's has some decent code based on bulhmann + gf, though not VPM.
