Thanx guys,
for all the comments.
@Linus
We are using the USB-CDC package from ST for our STM32F4. It comes with
a driver for the PC that make a COM port, for linux it should work the
standard linux kernel !? At the moment it is ok for us, but I am looking
for a way to have the USB also work with PCs standard driver config.

My kids are studying in Munich, may be we can meet in the next weeks.
The housing of oDiCo is made from plexiglas version 0.1 and filled with
silicon oel. The next housing 0.2 will be milled from POM and the
electronic will be an industry factored PCB. Awating to have it in the
lake in June ...

I had also the idea to implement the dive computer as USB mass storage,
but there a some more things to consider. In the moment we are looking
for a straight forward way. Because serial is running already we prefer
to use a already available protocol like the "SeaBear", you've
mentioned. We use the STM32F$ USB port without additional electronic, so
we are open for further improvements.
Any idea were I can find that SeaBear-spec in the mailing list, or just
ask Miika ?

This is interesting, I was starting to research on how to do that,
what kind of board, sensors, screen, etc. I wanted one that vibrates,
wireless charging, nfc or bluetooth and has a rechargable battery (for
freediving). I will look at you link later.
Good luck, I will follow your advances.

Hi list,
me and some friends are developing a DIY diving computer at the
moment.
See link (only in German at the moment):
http://www.skin-diver.org/sdiv/bastelecke/odico/
We intent to have it as a hardware platform for open source diving
software development. We are thinking to have it available as a
kit in a few month.
The software is in a alpha status, using Bühlmann ZHL16 Deco.
Odico uses a CORTEX M4 processor and can be programmed/debugged
from outside with CooCox.
We have made about 10 dives with hardware release OH0.1, deepest
47m/150ft. It's works fine, very reliable :-)
USB virtual com port is used for the communication with a PC.
"subsurface-divelog" seems to be good software/project for a Pc
front end and we would like to use it for odico.
So next is to implement a protocol into odico, compatible with
"subsurface-divelog".
So we have some questions:
Which protocol do you recommend us to implement into odico ?
One idea is UDDF/UDCF, is this a good approach ?
I also found some specs for the Suunto protocol and OSTC; is it
better to implement this ?
Other suggestions ?
I am very keen about your comments.
Thanx
Thomas Schrein
