I shall describe installing the Astroberry drivers.  The package contains drivers for a Focuser and Relay Board.  The focuser provides remote focussing for telescopes and camera lenses that is used from Ekos in KStars for remote focussing and even auto-focus.  This works in conjunction with hardware attached to the RPi to control a stepper motor. 

The Board driver is designed to control 4 relays for whatever purpose may be required.

The whole process is well described in Radek Kaczorek's GitHub page astroberry-diy   (same link as above).  I have used these drivers both as published and with modifications to suit my special needs eg. using the Board driver to control my roll-off-roof.  I'm happy to answer and questions but also Radek (RadekK) is a member on here and very helpful.

Oh dear!!  Just tried this with my second imaging rig RPi and get this on running make :-

From running the command that includes installing wiring.pi I get

wiringpi is already the newest version (2.50-1ubuntu1).

@RadekK can you help, please?

I should add that I ran the following commands, one at a time.

sudo apt-get install cmake indi-full libindi-dev wiringpi
git clone https://github.com/rkaczorek/astroberry-diy.git
cd astroberry-diy
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make

Since the problem is with wiringPi I could probably get round this problem by using an earlier version of the Astroberry files - I have copies.  I'll look into that later.  Meanwhile, I'm wondering why the change to wiringPi, may be a good reason...  Mind you I've had the earlier versions running without any problem for a few years.  I shall be interested in your views @RadekK.

Hi @Gina

Remove wiringpi installed with apt and use the latest version from the author's site http://wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/

The driver used to support low level library designed for raspberry pi only (bcm2835) and wiringpi. The latest version uses wiringpi only as it makes it more generic - now it can be used on other devices than raspberry pi and is not limited to a specific version of raspberry pi.

Thank you @RadekK.  That makes good sense.  I did try the autkor's site, drogon.net, but it was down temporarily.

Wow.  There's a blast from the past.  Back in the day Gordon Henderson and I used to hang around some of the same mailing lists (where "the day" was twenty years ago or more).

James

Gordon's wiringPi git is still unavailable

Quote

git.drogon.net is temporarily unavailable. Please look for alternatives for wiringPi, etc. -Gordon

so I shall have to resort to the bcm2835 setup as use in earlier versions of Astroberry as I have no idea when it will be available again.  I need to edit the C++ code for my ROR control but I was hoping to use the Astroberry code unaltered for the focuser for my second imager.  Oh well, these things are sent to try us!!

Are you sure that the site is not available? I have just opened it and downloaded latest wiringpi from https://project-downloads.drogon.net/wiringpi-latest.deb

There's this, too: https://github.com/WiringPi/WiringPi

James

Hmmm... Not as simple as I thought.  Seems there are other changes apart from replacing the bcm2835 library with the wiringPi library.

I think I shall need to take the micro SD out of one of my working RPi systems and copy all the Astroberry files to my desktop and then to the new SD cards.

Must be suffering from a dense spell!!

Connected human interface devices and ran the RPi in GUI mode.  Having removed to old wiringPi I downloaded and installed the new one from https://project-downloads.drogon.net/wiringpi-latest.deb.  The library appeared to install fine.  Next I closed down, powered up and accessed via SSH from the desktop.  I deleted the astroberry-diy directory and all it's contents to give me a clean start then entered these commands one at a time

git clone https://github.com/rkaczorek/astroberry-diy.git
cd astroberry-diy
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make

I thought it would work now but it still failed as before.

OK James. I'll try that.  I presume I need to remove the duff wiringPi with

    sudo apt-get purge wiringpi
    hash -r

Probably sensible, yes.

James

Hmmm...  Fixed the wiringPi error but getting others.

I think that means that you're not going to get anywhere unless you download the wiringpi source and build it yourself.  The existing one appears to contain references to functions in an incompatible release of glibc.

You may be able to ignore all of the other errors, which are only warnings anyhow, though it may be helpful if at least some of them are fixed.

James

I'll take a look at the code tomorrow.  I could also cut out the focuser section from the compiling list and see if the Astroberry Board compiles.  I don't want the focuser for my ROR remote control though I guess I could add a webcam to watch the imaging rig.

But where are the source files for wiringPi?

Here's probably best:  https://github.com/WiringPi/WiringPi/releases

It looks as though Gordon is no longer developing WiringPi, so I imagine the github site will be the primary source now.

James

At first I have been surprised by what @JamesF said but I have just read this http://wiringpi.com/wiringpi-deprecated/

So it looks like wiringPi will not be maintained anymore 😞 It's really bad news. However I fully understand Gordon. Maintaining a software is a nightmare nowadays. Few understand how much work it takes and how many nights one has to invest to keep things running for others for free.

Having said that I will have to move astroberry-diy back to BCM2835 library. It will take a while though so stay tuned.

Thank you @RadekK.  I used to write and maintain software so I know what you mean.  It's also why I really appreciate your efforts in this field.

I can see the problem with catering for different operating systems and a variety of SBCs and all the permutations that result.  ATM I am only interested in RPi 3 B and RPi 3 B+ though sometime in the future I can see wanting the RPi 4 to cater for faster imaging.

With wiringPi apparently broken I think my best option will be to take working versions from RPi 3 B and B+ and copy files to the new micro SD cards.

I thought just copying the astroberry-diy directory and all its contents from the working card to the new one would work but something was wrong with the bcm2835 library.  Maybe I should just clone the card and leave it at that.  I've found I can change the network name so that I can use both old and new at the same time.  That would give me a second imaging rig.  I'm rather surprised that just copying all the Astroberry files across and recompiling didn't work.  Must be something in the rest of the system - different version of something perhaps.
