Hello! I'm a KStars/EKOS/INDI newbie (1 week) so please bear with my stupid questions!

I am trying out KStars on my MacBook. I want to see if I can use it to run my equipment instead of using EQMOD + Cartes du Ciel + PHD2 + EOS BackYard running in Windows7 in a virtual machine on my MacBook.

So far so good. It's been a bit of a steep learning curve. Nevertheless I've successfully got KStars controlling my mount. It also works with my Canon 450D and my guide camera.

The specific problem I'm having is getting KStars/EKOS/INDI to work with the gamepad I use to control the mount at the telescope.

I understand I have to connect the gamepad to the mount in the Device Manager as described here: indilib.org/support/tutorials/135-contro...ools-menu-gt-devices

When I do this I get the error message: " ... make sure the package that provides the indi_joystick binary is installed."

Any suggestions how I do this?

Unfortunately, the joystick support is limited to Linux only.

OK. Thanks. At least that answers the problem. :-) Pity I didn't post the question here first. I'd have saved myself several hours of messing about.

That means I have got to work out a way of being able to adjust the mount at the scope since my MacBook is 5 metres away in my warm room.

Anyway, thanks again.

In the Mount tab there is a Mount Control button



When you click it you get this popup that allows you to fine control your mount

Wvreeven - hello, thanks for that suggestion. I'd discovered that popup already and had tried it using my iPad mirroring my macbook's screen. It works in a kind of fashion. A bit unresponsive, but that's probably down to the connection between my ipad and the Mac.

Hi, I am wondering if the joystick is actually on a Linux (Raspi) as a indi_joystick driver server, then shouldn't kstars/ekos client on iMAC be able to use it. Isn't it just XML indi protocol.

It uses Linux joystick API. For the driver to work on Mac, someone must add the MacOS joystick/gamepad equivalent calls

Hi, I am using the joystick driver on a Linux system, but was looking how to connect to it from the iMAC, so I don't need the driver yo be on the iMAC.

At first, When setting up my remote devices on the iMAC there was not a selection for joystick.

Not sure when, but I think after I connected to my remote server, it appeared under INDI Webcam Joystick. It has a nifty icon and hovering over it displays
"Available as REMOTE driver."

That is exactly what I was looking for. Thanks,
Oh, BTW, This is using Kstars 3.3.6 on the iMAC.

I am using PlayStation PS4 as my joystick on a remote Raspi. Under linux (jstest) the left joystick is #1, right joystick is #2, and the left digital joystick is #3.

Under INDI Control Panel Monitor the left joystick works fine. Manipulating the right joystick give garbled results showing up under #2 and #3. And the left digital joystick doesn't show up under #3. Note, all the Axes values shown in Monitor are correct though. And the buttons are correct. So I figure the algorithm for calculating the Joystick values from the Axis values has a bug somewhere.

Thinking perhaps I am running old joystick driver on Raspi, I did a git pull from master for the latest everything. Same results.

Looking at the source code it seems to me that the joystick algorithms perhaps assumes 2-axis joysticks, where the game controllers are 3-axis joysticks. X-Y-Trigger.

So I added some work around based on reading the "name" given at onConnect. In this case the name is "Sony Interactive Entertainment Wireless Controller".
I assume all PS3 and PS4 controllers return a name with "Controller" in it. Not knowing if XBOX sends something similar. Does anybody know what XBOX returns?
Hoping they return something with Controller in it... So I am looking for the word "Controller" in the name. If it is, I set a boolean PS3=true. Then in the rest of the driver code if PS3 is true I skip the current code and substitute the new code. Testing now. I will push this up to github. I am looking for someone with a XBOX controller so I can make that work too.

I just obtained a X-BOX game controller and it responds with name "Microsoft X-Box One S pad". So looking just for "Controller won't work.
Also, the position order of the buttons for 3 and 4 is flipped
PS4 button #
X-Box button #
X(Cross) #1 - Bottom of Diamond pattern - A #1
Circle #2 - Right of Diamond pattern - B #2
Triangle #3 - Top of Diamond pattern - Y #4
Square #4- Left of Diamond pattern - X #3

Not sure how people would prefer the button orders, but under PMC8 the STOP is #1 (Cross or A); Park is #2 (Circle or B); Un-park is #3 (Triangle or X).

For now I am just testing name for presence of either "Controller" or "X-Box and assigning a boolean PS1 to true.

Ahh! Setting boolean PS3 to true, Not PS1.

Hi,

After a long time "disconnected" due to work issues, I am now here again!

A simple question related to Joystick:

I already have a PS3 wireless control and I wonder if it is possible to connect it to my RPI/Stellarmate wirelessly. I understand that is it possible by cable (following your instructions) but I don't know whether I can use it without cable. As per your comments with yours (Thustmaster wireless) it seems to be possible, but please let me know how to do it.

Thanks!
