A task managing navigation app built for Qt

CrossDump

A task managing navigation app built with Qt. The project has been developed mainly to run on CrossControl's display computers.

Techniques used in the project have been documented in DOCS.md (text in Swedish).

Offline maps

An offline map of Uppsala has been generated and is included in the repo under offline-maps/. Below are instructions for installing the offline map on CrossControl's displays and on Linux.

View DOCS.md for further documentation on creating and using offline maps.

Install offline maps on CrossControl displays

Copy the offline map to the display's cache directory via SSH:

scp offline-maps/uppsala.db ccs@192.168.0.163:~
ssh ccs@192.168.0.163
...
sudo su
mv uppsala.db /home/root/.cache/QtLocation/5.8/tiles/mapboxgl/mapboxgl.db

Install offline maps on Linux

Copy the offline map to the local cache directory:

cp offline-maps/uppsala.db ~/.cache/QtLocation/5.8/tiles/mapboxgl/mapboxgl.db

Connect to a CrossControl display via Qt Creator

Go to Tools -> Options -> Devices -> Devices

Set "Host name" equal to the IP address of the display.

Test the connection with the "Test" button and finally click OK.

Running on CrossControl displays

Select compile target matching the display, for example CCpilot VS.

Add -platform wayland as "command line arguments". Optionally use -platform eglfs for drawing directly to the framebuffer. For the eglfs setting you also need to SSH into the display and run /etc/init.d/weston stop.

Under Run Environment:

• Set QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS to /dev/input/touchscreen0
• Set XDG_RUNTIME_DIR to /run/user/root

Profiling the app

Enable an FPS counter by adding the following code to the bottom of main.qml, which will print information to the console:

import com.crossdump.fpscounter 1.0

FPSCounter {
    id: fpsCounter
    width: 100
    height: 100
}
Text {
    text: fpsCounter.fps
}
