I have issued a pull request for the new feature.
Please find attached two histograms with LCG and HFW on/off.

Hello,

I built the latest Toupcam driver and tested the HFW switch with a DeepSkyPro 2600c IMX571 color camera.

Old SDK, LCG (no HFW obviously):


New SDK, LCG, HFW on:

(The values for the R channel are bad because my flats used here had too low red ADUs, so best look only at the G channel)

Fullwell capacity is approx. doubled, but e/ADU has doubled as well. Driver gain was 100 (lowest) in both cases. So unity gain in LCG+HFW on mode must be at a higher driver gain than 100. Has anyone figured this out? Or maybe a gain curve?

CS, Bernd

Actually toup has several sets of gain calibrations that I have measured in the past because the corresponding egain changes after the HCG switch. The first floor is Ascom's test, which could be a reference.

I will build and try HFW tonight

I have questions about current stable indi drivers for Touptek cameras. What are these options ("Dual gain" and "Dual gain mode") for? And why "Dual gain mode" is "High" by default?

Hi Denis,
Take a look at this page, which describes the functions as dual gain.

www.indilib.org/ccds/toupcam-cameras.html

High means HCG " high conversion gain" and is triggered by HCG Threshold in the gain value.

Is there a way to turn on the window heater when cooling is activated? I live in a high humidity environment and it would be nice that the heater turns on when cooling turns on.

the heater has its own function. But I think you could add it in when connect the camera

Please remember heater has level 0(OFF) 1 2 3 4

I don't think the INDI driver implements heater levels. The only choice is On/Off

I will have look on the implementation of this feature

I see different behavior for x64 and ARM64 INDI servers. When I start Ekos on x64 PC I see camera resolution 6224x4168 but for ARM64 resolution is 3104x2084
PS: I remove ~/.indi directory before each test
x64 INDI version: 1.9.9+202211300741~ubuntu22.04.1, ARM64 version is same

Found this in indi_toupbase.cpp sources: github.com/indilib/indi-3rdparty/blob/ma...di_toupbase.cpp#L801
Is this hack up to date?

Another strange behavior for ARM64. My program had to force set some properties (CCD_CAPTURE_FORMAT.INDI_RAW or CCD_OFFSET.OFFSET) even they are already set to proper values after INDI server start. Is this Ok?
