DO NOT RELY ON THIS APP FOR YOUR PRIMARY FLIGHT INSTRUMENTATION.
This app is meant solely as a backup and a convenient alternative display of available traffic and attitude information available from ADS-B through the Stratux ADS-B receiver with an AHRS daughter board.
Most of the hard work is done by the Stratux itself and this app is mostly a "dumb" display for that data. It is not meant to replace far more robust EFB apps. It is meant to be used as a simple display for the AHRS and available ADS-B data provided by the Stratux. This app originated as the Rosco Android app and was modified to run on a modest sized screen connected directly to the Raspberry Pi HDMI port, with a lot of refinements to the original app. It was then bakcported back to Android with all the new refinements and updted to display in either portrait or landscape modes.
This app depends heavily on the Qt libraries, version 5.12.0 as of this writing.

There are only a few controls:
The + and - buttons on the left side of the heading indicator zoom indicator and out from 5 NM to 100 NM of airspace surrounding you, which is in the center of the heading indicator. The current airspace size is displayed in the bottom left corner just above the G-Force indicator.
The Menu button has nine options:
Reset Level: Allows you to re-specify what is considered level in the Stratux software.
Reset G-Mtr: Allows you to reset the G-force indicator the same as in the stratux settings.
All Traffic/Cls Traffic: Filter traffic showing all (unfiltered) or only traffic that is within 5000 feet above or below you.
Exit RoscoPi: Exit the Stratofier display app back to the X-Windows desktop or the Android main screen.
Shutdown: Shuts down your Raspberry Pi. Not available for Android.
Upgrade: Upgrades the Stratofier software. You will see an LXTerminal window open showing compile progress. Once it finishes it will reboot and you should have the most recent version. This pulls the source code from github and compiles it. You need an active connection to the internet in order to do this. The easiest way to accomplish this is plug your ethernet port from your Pi into your router or any available ethernet plug on your network. Note also that this only upgrades the Stratofier software, not the Stratux software. That must be done according to the instructions from the stratux.me website.
All/Public/No Airports: Cycles through displaying all, just the public use, or no airports at all within the defined range of the heading indicator.
In/Out: Toggles whether or not to allow displaying traffic outside the confines of the heading indicator. In landscape mode this will allow distant draffic to be drawn to the left of the heading indicator (your left as well). In portrait mode it will allow traffic above the heading indicator (in front of you) to be drawn.
Tapping the center of the heading indicator shows a short selection dialog for Heading bug, Wind Bug, Clear or Cancel. Selecting a wind bug will query for both wind direction and speed.
Long pressing on the center of the heading indicator will display the crosswind component if you have a heading and wind bug set. It won't do anything if you don't already have those set.
The rest of the display should be self-explanatory. It's mostly similar to many other glass panel style all-in-one displays. Obviously the speed displayed is GPS-derived ground speed, NOT airspeed since the Stratux can't provide that data without an external pitot-static sensor.
That's it. All the data is supplied by the Stratux software. You can also use Stratofier as a standalone display on another Raspberry Pi as long as it can connect to the Stratux WiFi access point.
The only difference between the Raspberry Pi version and the Android version is that the Android version auto-rotates between portrait and landscape according to the orientation of the device whereas the dedicated screen has to be configured for that manually. The Android version has no shutdown button in the menu.
