I am new to INDI and to this forum. I am using Linux (Q4OS, derived from Debian 10) for about one year.
I owe a DMK 31AU03.AS camera and I want to use it on my Linux system.
I have installed CCDciel 0.9.75 and the latest version of INDI 1.9.1 which I compiled from sources.
I launch $ indiserver indi_v4l2_ccd from the command line, then I start CCDciel, which I configure to use with my camera.
I get the video stream without problem and I can change the frame rate successfully (1/30, 1/15, 2/15, 4/15).
I can also choose an exposure duration among a list (0.001, 0.005, 0.01, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 30, 60, 120, 240, 300, 600, 1200s).
But when I click on the button to start the exposure I get this error message:
"Failed ###.###-second manual exposure, no adequate control is registered."
In the past, I was able to take exposures with my DMK camera, using IC Capture (the manufacturer software) on a Windows computer.
I have reported the problem on the CCDciel list. P. Chevalley who is the author has directed me to this forum.
