Hey All, I've made a pull request for the ZWO EFW to Rumen's fork at github.com/rumengb/indi/pull/1 which makes the EFW work fine for me.
Adding support for multiple EFW is still a TODO.
There's error handling in there, but that can probably be improved.
Here's how it looks when in use :

2016-10-12T21:34:59: ASI Wheel: Entering ASIWHEEL::Connect
2016-10-12T21:34:59: ASI Wheel: ASIWHEEL::Connect id 0
2016-10-12T21:34:59: ASI Wheel: ASIWHEEL::Connect 5 filter slots
2016-10-12T21:34:59: ASI Wheel: ASIWHEEL::Connect current filter position 1
2016-10-12T21:35:12: ASI Wheel: Setting current filter to slot 2
2016-10-12T21:35:12: ASI Wheel: Entering ASIWHEEL::SelectFilter target 2
2016-10-12T21:35:15: ASI Wheel: ASIWHEEL::SelectFilter Done moving to 2

Dear Antares,

How do you test it?

Please provide some logs in order to be able to help!

Hello Rumen, thank you for your answer.

I did not practice a lot of tests.
I have pluged my EFW on the RPI3 (that run Ubuntu Mate) and launch Kstars then Ekos and finaly starts INDI in local mode.
For testing I choose the devieces as folow :
Mount : Telescope Simulator
CCD : CCD Simulator
Filter : ASI Wheel

The logs that returns indi is in my previous message.
May be there is a log somhere else but i dont know where. If so, let me know where to look :-)
Sorry not to be more accurate in my explanations and I hope my english is clear enough for you to understand (i m french) ;-)

Regards
David

Hi David,
I suspect there is something wrong with the udev rules.
Maybe running indiserver as root will shed some light.

Can you try to run indiserver from terminal like that:
$ sudo indiserver -v indi_asi_wheel

Then connect Ekos to localhost port 7624

Can you see the EFW now? Does it work now?

Hi Rumen, thanks a lot,

Just tested your idea this morning and it works.
Here is what I see in the terminal :
2016-11-16T06:11:22: startup: indiserver -v indi_asi_wheel
2016-11-16T06:11:22: Driver indi_asi_wheel: pid=4706 rfd=3 wfd=6 efd=7
2016-11-16T06:11:22: listening to port 7624 on fd 4
2016-11-16T06:12:12: Client 0: new arrival from 127.0.0.1:48989 - welcome!

Here is the log in Ekos
2016-11-16T07:12:21 EFW filter is online.
2016-11-16T07:12:12 INDI services started. Connection to remote INDI server is successful. Waiting for devices...
2016-11-16T07:12:12 Connecting to remote INDI server at localhost on port 7624 ...

What can I do now to make it works permanently ?

I tested whith my Atik 314L+ plus the EFW : both works fine together:-)

Once more, thanks Rumen

David

Hi David,
I have just made a pull request for Jasem with the new udev rules that fix your problem.
however you can apply them yourself:

as root edit:
/lib/udev/rules.d/99-asi.rules

at the bottom:
replace:
ATTR{product}=="ZWO EFW" ATTR{idVendor}=="03c3" ATTR{idProduct}=="1f01" GROUP="users", MODE="0666"
with:
KERNEL=="hidraw*", ATTRS{idVendor}=="03c3", ATTRS{idProduct}=="1f01", GROUP="users", MODE="0666"

then reload the rules:
$ sudo udevadm control --reload-rules

this will make it work without root.

Hi,
looks great! Is it possible to use this filter wheel standalone with USB connected to a raspi or PC ? My dealer told me that this filter wheel works only together with an ASI camera ?

Thanks,
Klaus

Hi Klaus, Who is your dealer? :)
Yes, the EFW works without ASI camera. It works with every camera that can work with 1.25" filters.

Thanks Rumen for the setup guide, I will test it as soon as possible.
To kkretzsch I equally confirm that you can use the ASI FW with other astronomy caméras.For example, I use it whith a Atik 314L+.
You only need a system to drive the FW...of course, choose INDI ;-)

Hello, everybody, hello Rumen,
Sorry to bother you once more :-)
Tonight a had time to do some more tests whith my EFW.
As you said that rules will be chaged in an update, i did the update of my RPI3. I simply lauche the Software updater of ubuntu mate.

Once done, I test to start indi in local mode and, like before, my EFW is wasn't recognize.

So I decide to makes the chages you talk about : change the botom lines of /lib/udev/rules.d/99-asi.rules
When i open the file, I saw that those lines alrady exists. (the update have been done)

Like before, I can use the EFW by lanching it in "server mode" so it is fine.
But, may be there is only little thing to do to make it work in local mode.

Feel free to ask me for more tests.

Best regards
David
