Well that certainly slams the brakes on it.

I was looking at the moonlite and robofocus code trying to understand it and it looks relatively easy. I couldn't relate the data I saw from wireshark at all.

OK, time to get started then. Can't wait forever. It would be nice to have the protocol, etc to speed this up, but it appears not to be an option.

Dmesg gives this when I connect the focuser:

44.703687] usb 2-1.1.1.1: new full-speed USB device number 7 using ehci-pci
[ 44.799169] usb 2-1.1.1.1: New USB device found, idVendor=0925, idProduct=7001
[ 44.799171] usb 2-1.1.1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 44.799173] usb 2-1.1.1.1: Product: Generic HID
[ 44.799174] usb 2-1.1.1.1: Manufacturer: SharpSky Pro
[ 44.802145] hid-generic 0003:0925:7001.0002: hiddev0,hidraw1: USB HID v1.11 Device [SharpSky Pro Generic HID] on usb-0000:00:1d.0-1.1.1.1/input0

It looks like it sets up 2 things under /dev -> /dev/hidraw1 and /dev/usb/hiddev0.

Under Windows, I ran Wireshark to capture some USB traffic. I've never used Wireshark before so I don't know what I am doing with it yet. :)

I've attached some captured output files that I'll start working on trying to understand. One file is just connecting the focuser only. The other has connection and moving the focuser back and forth. I've attached in case someone else can understand the data and/or tell me if I'm capturing the right stuff.

I've tried both of these drivers (for #1). I haven't tried #2 yet.
I'd like to get temperature compensation as well.

I believe it was done before by other users here (google the forum). Once you have the protocol, the rest is easy. You can customize moonlite focuser driver and change it to fit the protocol you found.


Ok, if we get nowhere with Dave, I'll start on this and see what I can discover.

That's what I've tried - maybe you'll have better luck.

Chris Ryan created a new topic ' Sharpsky Pro Focuser Driver' in the forum. 3 weeks ago

From what I can see there is no driver for the Sharpsky Pro focuser. I've tried to contact the manufacturer but have had no recent responses from him. In the past he mentioned that there had been no real need for creating the INDI driver so he hadn't gone to the effort.

Anyway, I've got one of these and I'd really like it to work under INDI. It works under ASCOM of course. In case it followed the same protocols as the Moonlite and Robofocuser I tried those, but had no luck.

I'm willing to learn whatever is required to get it done. Can anyone give me the path/process required to do this? How do I reverse engineer what it is doing under ASCOM? Once I have that info, what's the best way forward from there - copy and existing focuser driver and modify it for the Sharpsky? Any tips, etc would be greatly appreciated.

If it's appropriate, can that delay amount be configurable?

Have you tried connecting it as if it's a MoonLite or Robofocus unit? According to the website, it's compatible with the protocols of those 2.

Chris Ryan replied to the topic 'My gentoo overlay with indilib 3rd party drivers' in the forum. 10 months ago

I'm rebuilding my laptop again (from a new install) and I stumbled across the qsi + libftdi problem I mentioned a long time ago. Would it be possible for the qsi build to request a < 1.0 version of the libftdi installed, and to depend on it? While it's easy enough to add the package mask and do the install, it's currently the only thing I've found in the @indilibs build set that doesn't happen automatically.

Also, thanks again for updating! :)

It was in Kstars from memory (can't check at the moment, sorry). I know I set it there, but also importantly I told it not to over ride the mount settings.

Chris Ryan replied to the topic 'Strange geographic location for Losmandy Gemini' in the forum. 1 year ago

I can't recall getting time issues with the G11 Gemini, but it's never showed the location properly in INDI. For me, it shows something like (24) instead of Brisbane. However, the location coordinates seem to be fine. Since the location was messed up, I just set and control the location details via the handset (or website) and just let INDI read the values.

Chris Ryan replied to the topic 'MaxDome issues' in the forum. 1 year ago

That sounds like great progress. I'll do an update tonight (in approx 10 hrs) to try it out and see how it goes. I assume builds for RPi should be ready by then?

Do you have any plans or ideas to handle dome placement based on anticipation of where the scope will be? By that, I mean when the scope is issued a goto that will significantly change its position and therefore the dome's opening - will it detect this event and start moving to the required position at the same time the scope slews, instead of waiting until the scope stops moving?
