Hi all,
I'm currently testing some GPIO tasks to switch on and off things. I saw, that there was an gpio driver in INDI indilib.org/raspberry-pi/raspberry-pi-gpio-control.html where it was possible to switch several GPIO pins.

I set up a new Astroberry with the new 2.0.4 and tried to install the indi-rpi-gpio, since it was not installed from scratch.

Outcome was, that it is not possible to install the GPIO driver sinde there is a conflict with the pigpiod (it seem that there is a new one installed and the indi-rpi-gpio needs an older one)

Can somebody help here? Thank you.

Best regards

Jürgen
 

Just some mor information on the errors during the try of installation of indi-rpi-gpio: Just some mor information on the errors during the try of installation of indi-rpi-gpio:

You might need to build the driver from source. On Raspbian libpigpiod is included but it is not available under Ubuntu. So the libpigpiod library has been added to the INDI library (this is permitted by libpigpiod licence) but it is separated from the driver. This is an older version and the driver has a dependency on it.
So by building from source you can install just the driver without lipigpiod. The driver should work with the latest version of libpigpiod. If not, let me know and I can fix it.
I am the author of the driver but I am not very knowlegeable about Debian installer so build from source is what I would do in this case.

Hi Ken,
thank you for your reply. Building from source was also an approach I thought of but I didn't found the sources in github.com/indilib/indi (can aou tell me were the source is for the future?) and I'm also not so familiar with compiling.
But I found yesterday, that at least in Astroberry there is the driver "Astroberry relays" (github.com/rkaczorek/astroberry-diy) which is I think quite the same. The control of my relais worked with that :-)

I also use Stellarmate, but I didnt had the chance to check that in Stellarmate 1.6.1 (Kstars 3.5.6), as far as I remember, with the Stellarmate Version 1.6.0 (Kstars 3.5.5) it worked with the indi-rpi-gpio.

The source code is in the INDI 3rd party library github.com/indilib/indi-3rdparty
There is indi-rpi-gpio, libpigpiod and indi-asi-power which is the version that controls the ASI Air power controller.
The Astroberry relays driver also works fine and is much simpler. The RPi GPIO driver provides Pulse Width Modulation e.g. for controlling LED brightness or motor speed control, and periodic switching e.g. for triggering a DSLR imaging sequence
