Hi and thanks to all.
At the moment I' working on the sourceforge's hosted one (there are 2 version in two different repositories from the same author). I'm having some difficulties using his code, it makes my steppers (a nema 17 and a nema 17 PG27 reduction gear) move in a strange way - they move perfectly using some simple code).

I managed to attach the nema 17-PG27 to the focuser in a pretty stable way and now i'm using this guy code and try to find a way do make it usable on my steppers. I preferred the v168 as the Moonlite compatibility layer is fully functional on indi's moonlite driver. As I intend to use it as a "remote hand" for my focuser, i'm implementing the simplest schema (stepper, arduino nano, DRV8825 from pololu and a probe - is it used ?).

Thanks to all :)

Hi Paolo,
it is partially supported (i own one).
You may find it useful my topic here: www.indilib.org/forum/ccds-dslrs/2080-ex...ng-indi-qhy-ccd.html

TL;DR:
Qhy has not yet released firmware with unified low level protocol, so you have to use the libqhy which doesn't fully support it (e.g.: i'm unable to video stream nor set point nor activate the cooler).

Have a nice day :)

Luca Gervasi created a new topic ' Experience with QHY-183c using indi_qhy_ccd' in the forum. 2 months ago

Hello,
i'm going to share my experience with QHY 183c ( www.qhyccd.com/QHY183.html ) using indi_qhy_ccd with my RPi3 astrobox.

Qhy is experimenting with a common firmware layer that should allow us to use their cameras out of the box. Firmware is available in a indilib's repository subfolder ( github.com/indilib/indi/tree/master/3rdparty/libqhy/firmware ) which mimics libqhy sdk.

Once you attach your camera, kernel recognizes it as:

mar 24 15:54:51 astropi kernel: usb 1-1.3: new high-speed USB device number 6 using dwc_otg
mar 24 15:54:52 astropi kernel: usb 1-1.3: New USB device found, idVendor=1618, idProduct=c183
mar 24 15:54:52 astropi kernel: usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
mar 24 15:54:52 astropi kernel: usb 1-1.3: Product: WestBridge 
mar 24 15:54:52 astropi kernel: usb 1-1.3: Manufacturer: Cypress
mar 24 15:54:52 astropi kernel: usb 1-1.3: SerialNumber: 0000000004BE

You can then upload firmare image (QHY183.IMG) using this command:
fxload -v -t fx3 -I /usr/lib/firmware/qhy/QHY183.img -D /dev/bus/usb/001/006

Where 001 and 006 can be extracted from the previous paste (mar 24 15:54:51 astropi kernel: usb 1-1.3: new high-speed USB device number 6 using dwc_otg) and confirmed by an "lsusb" command looking for your idVendor and idProduct:
lsusb | grep 1618:c183
Bus 001 Device 006: ID 1618:c183

After loading the firmware (less than 1 second), the devices resets and reconnect as another device:
mar 24 16:07:48 astropi kernel: usb 1-1.3: USB disconnect, device number 6
mar 24 16:07:48 astropi kernel: usb 1-1.3: new high-speed USB device number 7 using dwc_otg
mar 24 16:07:49 astropi kernel: usb 1-1.3: New USB device found, idVendor=1618, idProduct=c184
mar 24 16:07:49 astropi kernel: usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
mar 24 16:07:49 astropi kernel: usb 1-1.3: Product: Q183-Cool
mar 24 16:07:49 astropi kernel: usb 1-1.3: Manufacturer: QHYCCD

Please not that it changed the idProduct (was c183, is c184 now).

The device is usable using indi_qhy_ccd as now (indi-qhy 1.6+r3007~201703232003~ubuntu16.04.1).

In my experience, it is not working as expected (unable to stream, wrong colors and so on), I expect that it will be developed a bit more :)

Hope to help someone.
Bye

Hello,
i have a crayford 2" hand focuser witch 1:8 reduction gear (standard skywatcher's focuser) I'd like to remote control.
My first idea was to use a moonlight packaged autofocuser but... it costs 3x my setup :D (about 800 euros in italy). So I was thinking about using someone else's diy focuser which uses a common driver already working on indilib.

For reference, this is my focuser: " nimax-img.de/Produktbilder/zoom/22264_1/...-Newton-Explorer.jpg "

What would you suggest?

Thanks

Hi!
Nick Altair just said that the SDK has been sent!!! :woohoo:
Is there a way I can help you? I mean...I both have hardware and few basic programming skills.

Thanks

Hello,
I have a GPCAM 2 from altair astro ( www.altairastro.com/Altair-GPCAMV2-IMX22...lanetary-Camera.html ). It seems to be not supported, so I asked in the Altair Astro Group on google ( groups.google.com/forum/#!forum/altair-astro ) which seems to be the correct line of contact to be used if it will be ever supported on indilib. Nick Altair answers:

Hi Luca, a long time ago I think in either late 2015 or 2016, we tried contacting the Indy team about sending them the SDK through their website, but no response, so we will leave it up to customers to campaign for this.

We are happy to provide SDK legitimate developers to enable Mac use.

We know most customers with Macs are using PC emulation software, because most astronomy software is PC based, but happy to help out. We would need some kind of official contact from whatever company needs the SDK, to our company.

Best regards, Nick Altair


Is there a way to be useful to make again contact or cooperate with you about that camera? (I'm not an active developer, sorry).
Thanks
Luca
