I noticed recently that the OSTC4 source code is now available for download. Is this intentional ?

Looks like some great improvements, I look forward to trying them! Thank you

I suspect that once you have recharged the battery you will have to reset the battery status by using the battery reset menu :

Settings -> More... -> More... -> Reset Battery -> New Battery -> Internal 16650

And thank you for the information Matthias.

If the battery on the OSTC2 2017 is completely emptied, the "New Battery" menu is shown when the device is placed on the Qi charger.

Is the battery type "Internal 16650" / Type 4 ?

Is this battery user-replaceable or is it potted in resin ? I'm just curious.

What is the maximum/fully-charged ...

It looks like your OSTC3 is set to the wrong colour display mode ?

Perhaps try :
Menu -> Settings -> Display Settings -> Colour scheme -> Select "Standard"

Good day

I have an OSTC 3, which has an infrared data port. I was wondering if there is a way or a planned device that will allow an OSTC 3 to access Oxygen sensor readings from a JJ CCR via the DiveCAN system ?

As far as I understand the DiveCAN implementation on a JJ CCR makes an auxillary port ...

Thank you!

I bought my Sport before I finished my OWD certification. Lately I've been diving with a buddy and we've been using GUE's Minimum Decompression Limits, which effectively replaces NDL. It would be very useful to have NDL as optional, so that during these "team" dives the display of the computer doesn ...

Hi

Would it be possible to make the NDL display on the OSTC Sport optional ?

Thanks

I also use Subsurface, it's amazing software, thank you to the developers .

I recently visited DeepStop in Germany (and bought an OSTC 3). I got a chance to play with an OSTC 4... It's big, but really awesome. Clarity of the display was incredible, very responsive.

Does the code running on the OSTC 4 run "baremetal" or does it run on top of an operating system ? Does the ...

Good day

Is the OSTC Plus open source ? Can a person compile and load custom firmware ?

Thanks

Is the OSTC 4's source code written in a similar way to the OSTC 2's source; mostly ASM with some C (deco_p2.c), limited used of local variables in favour of global variables, no input variables on functions and no returned variables in favour of global variables, highly procedural/not object ...

Thank you for the update. I love my OSTC Sport (:P).

@previous poster : My OSTC Sport shows the same uptime.

Thank you very much Matthias --- once I figure out what the inputs (int_I_pres_surface) are I'll be able to compare it to other decompression implementations .

I would have expected that these kinds of queries would have been welcomed by HeinrichsWeikamp. They're not difficult questions to answer; "yes, yes, no" or "You need to buy an OSTC 2/3/4 to ask these kinds of questions".

I'm currently trying to simulate the decompression model (p2_deco.c) on an ...

In your hwos_code repository you have automated tests for gas volume consumption in "Tests", do you have tests for your deco model ?

Good day

I have an OSTC Sport, which I am very happy with. Someone recently asked me how certain I was whether or not the decompression model implementation on the OSTC Sport is accurate and I couldn't answer.

So I was wondering, has the decompression code for the Sport ever been checked by a ...

You really should use the SAFT batteries; they last much longer and they have a highly predictable discharge profile. Their power output is also not affected as much by cold temperatures.

Alkaline batteries are unreliable and different manufacturers make batteries with unpredictable discharge ...

I suspect the Sport uses a bootloader that verifies a signature on the firmware to be booted or refuses to flash firmware that isn't signed. There are many ways to prevent someone from running unauthorised code on an MCU.

In any case, coding in ASM would be painful ;) . It is nice to be able to ...

I bought an OSTC Sport and so far it has been reliable and easy to use. Everyone asks me about it because no one has seen them here before (Cape Town) and it looks really nice, well made and comfortable to wear/use. I'm very happy with my purchase.

I would say the only thing missing is air ...

Subsurface is very good... it's very nice to have a piece of software that can download from different computers on any major OS and stores the data in an open format (XML). HW should stick to firmware .

Hi

That is disappointing, but I will probably buy the OSTC Sport anyway.

Thank you for the response .

Hi

I'm considering buying an OSTC Sport. I like open source software and I mostly use Linux; being able to read logs on my Linux machines is important to me. I like to know how things work and it is nice to be able to modify them if necessary.

I've been trying to find the following information ...
