Updated - Feature requests ccr ostc4

Post by swissdiving »

For next HW series:
➡️ 1. Vibration alarm on high/low PO2 for CCR (Please!!)
2. Cave function in OC AND CCR mode
(Please!!)
3. Add scrubber time for a second scrubber (Sidewinder or Revo) ---> the current implementation is of no use, as only one scrubber counts down. :(
4. Total dive time for all ccr dives (analog to hours of operation but CCR only)
5. Simpler way to go back from Bailout to CCR mode
6. In CCR fixed Setpoint mode only 3 ppo2 are available. This is only of value for eccrs, for mccr it would be good to have 4 or as pre 1.6.5, 5 setpoints that change according to set depth.

Been diving the beta now for several months on my primary ostc4 (fisher) and backup ostc4. Works no problem.

Loving it.

Matthias, when will you release the 1.5.8 Beta into production?
I've now had close to 60h on the Beta and it works pretty much perfectly!

Hi all.

I am a CCR diver, and have been implementing some improvements to the OSTC4 firmware, with a few of them CCR related. I have some proposals that address some of the points raised in this list, and am happy to work on others with some more input on what the requirements are:
swissdiving wrote: Friday 16. April 2021, 20:52 For next HW series:
➡️ 1. Vibration alarm on high/low PO2 for CCR (Please!!)
As a step in this direction I have tried to make the scrubber timer more visible when it is about to run out:
- display in yellow when < 30 mins left;
- display in red when <= 0 minutes left;
- display negative duration when < 0 minutes left.

swissdiving wrote: Friday 16. April 2021, 20:52 2. Cave function in OC AND CCR mode
(Please!!)
Not sure what this is - can somebody provide a description of the requirements?
swissdiving wrote: Friday 16. April 2021, 20:52 4. Total dive time for all ccr dives (analog to hours of operation but CCR only)
Is this meant to be in SYS / Information / Dive records?
Not sure this makes sense in there, as this is at the moment a simple 'machine hours' counter for the hardware, and the 'number of dives' is an internal counter that can be reset by things like firmware updates - i.e. it is not calculated from logged data.
Probably a better place to keep track of this will be a dive log application like Subsurface?

I have got a proposal for this, please provide feedback: https://github.com/mikeller/ostc4/pull/14
Happy to provide a test build of the firmware if somebody wants to test.

Some of the CCR related improvements that I have done so far, but that have not yet been included in a release:

- Improve the automatic setpoint switching.:
This makes the setpoint switching behaviour identical to automatic switching that is done by most CCRs, making it possible to configure the OSTC4 as a standalone back up dive computer that switches at the same time as the CCR.

-Added surface mode CCR summary:
