All Sky Camera Revisited

[Gina]

Yes, that's what I think too. 

BTW - Now in Ubuntu Mate on RPi connected via WiFi and Firefox is running fine now.  I'll try the script but as you say, doubt it will work and it so I'll comment out the dpkg check.

[Gina]

gina@asc:~$ sudo apt-get install git
[sudo] password for gina: 
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
gina@asc:~$ sudo apt-get install git
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)

gina@asc:~$ 

Hmm...  Now getting a problem earlier on!!

If this is on the Ubuntu 16.04 installation, perhaps that genuinely is trying to download all the latest updates?

MATE System Monitor shows PulseAudio and itself running only.  Processor is active though.

It's definitely doing something.  Firefox is running - maybe it's that.  I'll close Firefox and see what gives.

[Gina]

Only difference closing Firefox made was to reduce memory useage.  Something is exercising the CPU and at quite a high rate.

Screenshot of System Monitor without Firefox running.

[Gina]

Restarted the system and the CPU activity was low so tried the command again in Terminal and it worked   Now to try the rest...

[Gina]

Voila!!!  It's all working - including the script

[Gina]

Script finished and ready for rebooting.  At this point I can test it with the camera then go on to install my own focuser driver alterations.

[Gina]

Rebooted but now the GUI is not working - just showing four raspberries.  However, the WiFi is working and I have been able to SSH into the RPi from Mint.  A new IP address was allocated to the ASC so had to follow the instructions to clear the old allocation.

Phew!!  I need a break now.

[Gina]

It works!!  ?  Next is to load the Astroberry drivers, install my modifications, compile and install drivers.  ATM I only have the camera driver operational.

Here's a screenshot or two from the KStars FITS Viewer - camera sitting on a box in my living room.

Think I'll save an image of the SD card before continuing.  I think there's a Linux app but forget what so I'll use my Win7 laptop and Win32 Disk Imager.

[Gina]

sudo shutdown -h now

Safely shuts the RPi down.

Waiting for backup to finish...

[Gina]

Done.  Onwards and upwards... ?

[Gina]

Ran these commands.

sudo apt install cmake
git clone https://github.com/rkaczorek/astroberry-diy.git

Now need to do a bit of editing to remove unwanted drivers from Radek's Astroberry set as per my Tutorial  page Installing 3rd Party Drivers.

[Gina]

Oh no I don't!!  Radek has already removed the unwanted drivers from his repository.  Except that I don't require his Focuser as I will install my own.  Doesn't hurt to leave it.  Less editing means less chance of errors!!

[Gina]

I'll just go ahead and install the Astroberry Drivers as shown on the Astroberry github page.

sudo apt-get install cmake indi-full libindi-dev
cd astroberry-diy
mkdir build && cd build
cmake -DWITH_WIRINGPI=OFF -DCMAKE_INSTALL_PREFIX=/usr ..
make
sudo make install

[Gina]

That all worked ?  Then tried

indiserver -m 100 -vv indi_asi_ccd indi_rpifocus indi_rpibrd

In the Terminal to RPi and from Mint menu - ran KStars and Ekos and started INDI getting the Astroberry controls as expected in addition to the camera.

Next job is to replace a couple of the Astroberry source files with my own versions (edited from the originals to suit my hardware).

Edited April 2, 2019 by Gina

[Gina]

Shut down RPi, put card in Mint and replaced the rpi_brd.h and rpi_brd.cpp files with my own, renaming the originals just in case.  Ejected card and replaced it in RPi and powered up.  Now I'm getting "No route to host"!!  I haven't touched anything to do with the WiFi.

[Gina]

Hmm... worked with the IP address.  Now to recompile the C++ files.

Edited April 2, 2019 by Gina

[Gina]

That worked and I'm getting my custom controls.  Now for a cuppa before I connect up the hardware and test the focussing etc.  Also, it would be a good idea to back it up while I'm getting my cuppa.

Edited April 2, 2019 by Gina

[Gina]

Testing the focussing, I have a hardware fault.  Coarse and Fine work but not the Direction.  It's either the RPi or the A4988 driver module as the voltage on the Dir pin changes from 0.02v to 0.4v with the buttons.  So it's changing but not to 3.3v.  I'll try unplugging the driver module and test again with DMM.
