Pi and WIndows questions

[ag6ay]

Hi I have some questions and observations. I'm looking forward to comments Cheers Rick AG6AY

Installing on Pi using Stretch

1. I found line 51 in graphics.py needed 'x11' in the list before init_display() would work (the full list of possible values is at https://www.libsdl.org/release/SDL-1.2.15/docs/html/sdlenvvars.html) but debian-based Pi only needed 'x11' added)
2. I found packages python-pygame and numpy pre-installed installed with Stretch and I did not need to add them manually.
3. I did not need to build basemap ... this seemed to work ...

After installing Stretch ... sudo aptitude update sudo aptitude upgrade sudo aptitude install libgeos-3.5.1 sudo aptitude install libgeos-dev sudo aptitude install python-matplotlib sudo aptitude install python-mpltoolkits.basemap git clone

I say seemed to work because running the ./collector.py and ./dashboard.py brings up the logo and marque moving line at the bottom of the screen but i have not yet gotten the various dashboards to visually cycle on the screen.

Do I need data in the database first?
Can you provide more instructions on using replayer.py?

Installing on Windows

1. I am stuck on Step 14 and 15 of INSTALL_WINDOWS.md. "call ..\Scripts\activate.bat" finds nothing to execute.

Hi,

You probably need to add x11 if you are running x-window system. I never did that. Please make a pull request so that can get added.

Until there is data, not much should show, except for the map.

I don't know about the windows installation. You might want to ask VE1GPY, he gave me that.

to use replayer, change the name of the N1MM_LOG_FILE in config.py to point at a log file you want to process into the system. This simulates the UDP messages from N1MM and sends them to the collector. if you have a old log file from field day, you can use this to test.

Thanks for the info

What I meant by ....

"I found line 51 in graphics.py needed 'x11' in the list before init_display() would work (the full list of possible values is at https://www.libsdl.org/release/SDL-1.2.15/docs/html/sdlenvvars.html) but debian-based Pi only needed 'x11' added)"

... is that, with the current Stretch Raspbian version, the dashboard.py log was showing 'No suitable video driver found!' before terminating until I made the following change in graphics.py ...

From: drivers = ['fbcon', 'directfb', 'ggi', 'svgalib', 'directx', 'windib'] to: drivers = ['x11', 'fbcon', 'directfb', 'ggi', 'svgalib', 'directx', 'windib']

... after which the program does not terminate and the logo with scrolling marque line is presented. I do not get a map, however.

I did not actually have to install x-windows ... it was already part of Stretch and was the driver os.putenv('SDL_VIDEODRIVER', driver) needed for my OS.

So I should have seen a basic map? Hmm. Perhaps sudo aptitude install python-mpltoolkits.basemap did not work for me after all. I will look over weekend.

I would like to request write access so that I can create an x11 branch using ... git push origin x11

.... or do I fork first and push there?

Fork then push to your fork and make a pull request. Thanks!

the main branch now has

drivers = ['x11', 'fbcon', 'directfb', 'ggi', 'svgalib', 'directx', 'windib']

so I am closing this issue.
