INDI Library v1.7.6 Released. (27 Feb 2019)

First release of 2019 comes with quite a few new drivers across the board along with significant performance improvements to INDI camera and live streaming performance. Many drivers received significant updates to improve performance & stability, while a few were re-written from scratch to be in line with INDI standards. Here are some of the highlights:

You might want to start with some USB Serial monitor/sniffer and watch the traffic as you issue command and receive response. 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.

Hi,

I know, to email, the original designer of the Sharpsky focuser - Dave Trewren... I'll drop him an email to see if he can get interested...

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

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

It looks like Sharpsky focuser is MoonLite/Robo compatible (as described in Other features on the focuser site )
This means that you can either:
1) use MoonLite/Robo control box and MoonLite focuser driver
2) skip any control box and use any stepper motor controller (see this post ) or use Astroberry PiFace driver (see this post )

Option #2 will let you just control the stepper motor and will not provide all other focuser capabilities (i.e. temperature compensation etc.). Depending on level of compatibility option #1 might provide you with support for all capabilities.

I'd be interested as well. I asked Dave some time ago as well.

I got an email back from Dave.... I have asked him, if he has some time as he does have a day job, to join the forum to potentially join in the discussions....

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

Hi Phil

Did David get back to you on this? I did ask him a while ago. I have the same focuser.

Hi,

The last email I had from Dave said he was going to look at the Indi project if I could give him various links (which I did) - the final sentence was, "it's sad, but it just boils down to time... or the lack of it"

It sounds like he would like to get involved... but can't afford the time...

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.
