Argonaut m7 touch monitor, sunscreen readable, P7X Water Sealed Front

[mgrouch]

I’ve got chance to play a bit with Argonaut
m7 gen 2 and pi 4 with openplotter 2 beta.

1. Screen resolution is a bit low 800x480. 480p
But it’s workable

2. Touchscreen support from Raspbian and OpenCPN
way poorer than on Android.

Only one finger touch.
No double click emulation.
No on-screen keyboard.

3. No speaker built in into M7 monitor

It seems if you have 3 choices for a cockpit
universal display

1. Windows PC stick with Open CPN in cabin
and touch HDMI display in cockpit
2. Android Tablet with Open CPN in cockpit
and some kind of NMEA multiplexor in cabin
(KPlex)
3. Openplotter in cabin with HDMI touch display
in cockpit.

due to poor support of multitouch in Linux
option 3 so far looks least attractive.
I haven’t tried first 2 though they might have
their own drawbacks.

How do you set up touchscreens with multitouch
for a cockpit with OpenPlotter 2? I just
couldn’t figure it out.

thanks,
