Hello again !

The code is now compiling correctly and I have been able to start indiserver, start CCDciel and use the Panel (only the Tracking part of the code is working, the rest is still simulated).

If I tried to use KStars (as it is the only way I know to be able to test GoTo functionalities with Indi) ... I can see my driver listed but when I connect indiserver I get an error message like "driver was not found on the system".

I checked and the driver is (together with the other) in /usr/bin while the xml is in /usr/share/indi

With KStars I can use indi with indi_v4l2_ccd and indi_gphoto2_ccd ... which have files located in the same place of arduinogoto_telescope ...

Any idea ? I tried to strace indiserver but without success !

Cheers

I checked what I sent you, and in the XML file, the file is called "indi_arduino_telescope", while the executable is called "indi_arduinogoto_telescope", so please change the name in the XML file to that of the executable exactly and run sudo make install and try again.

Hi,

yes that was the reason ! Thanks.

I am now trying to debug the code using QT creator 3.5 (I have being using Visual studio years ago and I found QT really a good development environment). I watched your videos here:
www.indilib.org/develop/developer-manual...ent-environment.html

After some try/error I got my driver built with debug symbols in it (the size is more than twice the normal build) ... but ... there is always a but !!

As my driver is a telescope driver and kstars require to have a CCD driver as well so I tried both indi_v4l2_ccd (with my laptop webcam....) or indi_gphoto_ccd and within QT, the application start like this:
indiserver -v indi_v4l2_ccd indi_arduinogoto_telescope

The issue is that, I just use:
indiserver -v indi_arduinogoto_telescope
I can debug with no error (breakpoint works), but I cannot test it with kstars.

If I use
indiserver -v indi_v4l2_ccd indi_arduinogoto_telescope
indiserver -v indi_gphoto_ccd indi_arduinogoto_telescope

I got a segmentation fault ! Any idea or recommendation ?

Cheers

The driver you want to debug should always be the first. i.e.
indiserver -v indi_arduinogoto_telescope indi_v4l2_ccd

Hi,
I'm also trying to morize my mount. Could you send again your project? Dropbox links are not working anymore.

Hi,
sorry to be away for so long but many nice things happened (a daughter and a new job) and I didn't have time to work on the project. I will create a git repository and upload the latest set of files ASAP then post here the link.
Thanks

Hi, I am succesfully using your driver for guiding.
However I don't know how to enable GoTo. You have written "I can see that GoTo is now available. " Where is this option?

Hello topaz, francesco and Jasem
I am also trying to get my head around this topic. I am using the Arduino-ST4 for guiding, but would like to use it to move the telescope by pressing buttons...
I have successfully done that under Windows, but would like to make the step to Linux in order to be able to put eveything on an Raspi. I am working i to achieve what Franceso was trying (and maybe he succeded in) to allow slewing of the telescope by giving it permanent guiding pulses (=pressing a N/S/E/W button on screen). GoTo is yet another step after that...
So, if you have made any progress here, please share it - it would help me on my learning curve.
