Hello Nigel,

SVBony introduced the ability to store the settings in a recent SDK :

<< SVBCAMERA_API SVB_ERROR_CODE SVBSetAutoSaveParam(int iCameraID, SVB_BOOL enable); >>

I don't use this feature. In my mind, it's the wrong way to go. The settings should be stored in the client software, not at low level, or you may experience
the issue you just discovered.

Sadly, AstroDMX seems to use it.

Thanks for sharing your experience.

Best regards,

Hi folks,

I'm working on the temperature control on the SV405CC, and I have a question.

The SVBony SDK controls for camera cooling are somewhat different from the INDI default controls.

SVBony provides :

- Powering the cooler ON/OFF
- Setting the cooler power (0 - 100%)
- Reading the current temperature
- Setting the target temperature

INDI provides :

- Setting the target temperature
- Setting the cooling/warming ramp
- Setting the temperature hysteresis

What should I do ?

- Try to wrap all the SVBony controls onto the INDI controls, and only them ?
- Try to mix the INDI Controls and the SVBony SDK, with extra controls ?
- Provide only the SVBony controls, as a proprietary panel, without the INDI default controls ?

Please notice that I don't have the camera yet (waiting for delivery), so, I'm note able to see how the SDK controls really act.

Best regards !

First implement and release the INDI control, then implement the SVBONY control. Or vice versa. Why not implement it in whichever way can be released sooner?

I too am waiting for SV405CC to ship, and SVBONY tells me it will ship at the end of this month.
Hopefully the SV405CC will arrive in your hands soon.

Hi Collin

are you saying the settings are stored in the camera and retained through power cycles?

That sounds a rather pointless and error prone thing for them to decide to do. Would have thought it would be cheaper/easier and thus more profitable to leave it to a client to set.

Is there some form of reset to defaults call that could be made when the indi driver is initialised otherwise people are just going to keep hitting what seems like random errors?

INDI has CoolerSP (Cooler ON / OFF) control. You can also add your own property for setting the cooler power. I presume there is "automatic" mode when the power is set automatically, and another where it is manual. You can also add another switch for that.

Hi Nigel,

I agree with you, pointless and sensitive.

<< Is there some form of reset to defaults call that could be made when the indi driver is initialised otherwise people are just going to keep hitting what seems like random errors? >>

I don't know yet. I have to explore the APIs deeper.

Hi Jasem,

Thanks for your answer.

I think I will choose this option :

<< - Try to mix the INDI Controls and the SVBony SDK, with extra controls ? >>

Hi Collin

Did you receive your SV405CC?
I received mine last week.
I am testing it with SharpCap but have not done astrophotography yet.

If you don't mind, can you tell me when the SV405CC INDI driver will be released?

I have created an indi_sv305_ccd driver for the SV405CC.

After a little while, I'll send a pull request to GitHub.
The following changes were made in addition to the SV405CC support.

1. Improvement: OFFSET suppot on Ekos Camera module.
2. Fixed a mutex conflict that occurred when two or more SVBONY cameras are connected.
3. Added break to case SVB_BLACK_LEVEL of Sv305CCD::Connect.

Thanks

Don't know if this is related to this change but now, the indi_sv305_ccd crashes with or without any camera plugged-in:
