Hi,
We are very fortunate users of INDI for driving a radiotelescope interface at F4KLO in La Villette, Paris (France).
The radiotelescope entered into exploitation phase a while ago to contribute public astronomy demonstrations.
At our radioclub F4KLO we also operate the radiotelescope to perform radio communications by reflexion of radio signal on the moon (Earth-Moon-Earth).
We want to add remote individual users to let them perform some experimental radioastronomy ad we have created individual accounts on our Linux machine.
Presently main user works fine with Python clients driving the radiotelescope through Indi library.
However for new Linux users we are facing a problem with a python client that needs to import PyIndi.
How can we share PyIndi ? Is it necessary to install something for each new user ? Can we use a Path in some file ?

Thanks for help.

Hi,

While tutorial_two example driver is running top Linux utility shows as much as 95% CPU occupation !

We have nearly achieved development phase of our INDI driver based on above example.
It will soon enter into validation phase.
La Villette Radioelescope is a thirty years old object and mechanics have suffered from time erosion. It is a 10 m dish initially built for Galaxy atomic hydrogen 1420 MHz listening.

Our driver was developped after tutorial_two example. It is now able to perform GoTo at low and high speed and compensate for Earth motion, following INDI clients Stellarium and Skycharts requirements.

Driver is running on a RaspBerry Pi connected to an interface card via /dev/USB0 driving antenna motors electronic control interface.

As shown by Linux "top" utility, indiserver is using less than 1% CPU whereas tutorial_two is using up to 95 %CPU time even when not performing any task. So does our own driver.

However we found a very simple solution that corrected this situation and now our driver is only using 0.6 to 1% of CPU even when performing a GoTo asked by client Skycharts.

Bernard,
