[enhancement] show radar page using hdmi / dsi screens

[Stefan-Kosker]

Feature request / discussion: auto navigate to radar.html in full screen mode after successful boot.

Currently, in the vanilla stratux, only way to see the traffic is using Skydemon e.g. or another device to connect to stratux and navigate to radar.

I don't see why on successful boot stratux can't open a chromium and show a full screen version of radar.html hosted on localhost. This would also make it possible to change the settings directly on the device

I see, that this requires booting rasp-pi on gui mode, which additionally uses more resources and doesn't help with the heat dissipation. This is definitely a consideration. This could be a setting itself which you have to update via WLAN.

Currently working solutions are using a second raspberry pi to connect and call the browser and show it. Or use straight up a mobile phone to show the page. Or just skip it and use Skydemon. All of these solutions require a second device. I think it would be neat to have a built in display using the dsi connector or hdmi + last usb for touch-enabled to use the + - buttons.

Reasoning behind this feature is: In cases your iPad dies, you are not directly also blind to other traffic. This single point of failure is very easy to fix, if we can provide a fallback display.

I am aware of the project stratux-radar-display. But it is also another project supported by a single person / small team. In the aviation world, where redundancy is the main line of defence, trying to eliminate unnecessary points of failure without redundancy would be a smart thing.

In case this feature gets implemented, I will contribute with a tutorial for display + tx version and also 3d print files for a case using a 4.3" dsi touch screen for raspberry pi

Thank you very much.
