DMK41 AU02.AS : How to configure it with INDI ? #472
I'm not sure I understand the problem, Ekos exposure can be set to any value, you can set it to 0.01 and it would send that over to the INDI driver. What do you mean by not accurate enough?

EDIT: Also Ekos does not record AVI.

DMK41 AU02.AS : How to configure it with INDI ? #473
I thought I would have the choice between 0.00, 0.50 and 1.00. I just saw that I can write 0.01, 0.02 ... But not below. Impossible to get 1/10000 (0.0001) for example

I changed the decimal precision to 4, so now you can write 0.0001

Thank you !

Do you plan to integrate video recording via INDI? Launching V4L2, when I open the window streaming, there is already a "pause" button and a button "capture an image" (with a list of possible formats). It "would suffice" to add a "capture video" button, perhaps with a timer. But I always ask too much! :oops:

There are no plans now to add AVI recording into KStars as it requires a few extra dependencies that I want to avoid for the time being. Maybe in future versions :-)

I tried to enter 0.0001 in Ekos (ccd v4l2), it still refuses to go beyond the second decimal

DMK41 AU02.AS : How to configure it with INDI ? #558
Hi,
I am right where you were here. I have a DMK 21AUO4.AS and have never been able to get to work under linux. I clicked on your link, but cannot find a procedure there. I also have a Celestron NI5 which is a rebranded IS camera that I would like to get running under linux. Could you cut and paste the procedure so I can try it?
Thanks,
John

DMK41 AU02.AS : How to configure it with INDI ? #561
I don't have linux (Fedora 20) recognizing the camera(s) yet. I have installed libindi but barely have a clue as to how to interface anything yet. I know first I need to get the cameras recognized. (on bootup dmesg shows the cameras as correctly identified, but v4l says there is no video device) That is where I am stuck, so I have a way to go. The installed libindi is 0.0.6-6.fc20 for a 64 bit linux machine.

DMK41 AU02.AS : How to configure it with INDI ? #563
I have a DMK 41AU02.as and I also had never managed to make it work under linux, until I tried the solution described here
posts #12 and #13:


My Linux engineer told me:
This command tells the uvc driver that it is responsible for the camera

echo "199e 8101" | sudo tee /sys/bus/usb/drivers/uvcvideo/new_id

If the number "8101" does not work, you can run dmesg to determine the correct idProduct.

Best regards

Indeed. I am not in a position to test with all the different models, but this solution is looking promising.

I'm not at all convinced this is the most efficient way to do things, but on my Mint 15 (based on Ubuntu) installation I now have a file /etc/udev/rules.d/70-tis-cameras.rules which reads:

Code:

# Udev rules for TIS CCD cameras
#

ACTION!="add", GOTO="tis_end"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GOTO="tis_test"
SUBSYSTEM!="usb_device", GOTO="tis_end"

LABEL="tis_test"

ATTRS{idVendor}=="199e", ATTRS{idProduct}=="8101", RUN+="/usr/local/bin/config-tis-camera.sh"

LABEL="tis_end"

and a script /usr/local/bin/config-tis-camera.sh:

Code:
#!/bin/bash
#
# Load and appropriately configure UVC video driver for the USB TIS CCD
# cameras

USB_ID="199e 8101"
/sbin/modprobe uvcvideo && echo $USB_ID > /sys/bus/usb/drivers/uvcvideo/new_id

This appears to get the camera recognised by the UVC driver when it is plugged in. I believe that any V4L2-compliant application (that can handle debayering the raw image data from the camera) should then work with the colour cameras. I can't test the mono models as I don't have one, but I think this should work for all of the USB DMK, DFK, DBK 21, 31 and 41 CCD astronomy cameras and perhaps some of the others as well. If I can find someone selling a used USB mono camera that might be useful to me at a reasonable price (probably the DMK21.618 or DMK41 as I'm unlikely to use the others) then I'll give it a try, but they don't seem to come up that often.

Having reached this point I also found a couple of German web pages suggesting the same solution is valid for some microscope cameras, but I have no first hand information about those.

I'd suggest that it would be very helpful if this information were made available somewhere on the main TIS website?

It worked for me. Do not forget to make these files executable!

Hi,
There may be a small error in the uvc driver as the Imaging Source camera (199e:8101 DFx 21BU04) is listed as being recognized on the uvcvideo site but the idProduct in the linuxtv.org source tree seems to be different (0x8102):
/* The Imaging Source USB CCD cameras */
2433 { .match_flags = USB_DEVICE_ID_MATCH_DEVICE
2434 | USB_DEVICE_ID_MATCH_INT_INFO,
2435 .idVendor = 0x199e,
2436 .idProduct = 0x8102,
2437 .bInterfaceClass = USB_CLASS_VENDOR_SPEC,
2438 .bInterfaceSubClass = 1,
2439 .bInterfaceProtocol = 0 },

You could send a request on the uvcvideo development list for this to be corrected or simply ask them to add
your camera idProduct (0x8101).
Maybe someone from Imaging Source can confirm the idProducts they are using for their uvc capable cameras.
