OpenPlotter 4 roadmap

[Loffy]

Hi Loffy, I have done the same setup and I’m about to release a video of this setup at 10am today (15mins). The basic process is to flash the sd card and then use the sd card copier to move the image to the SSD. A couple of changes on the pi config and it just works.

It’s extremely fast on a pi5 and I think it’s the best combination you can build at the moment. Add a MacArthur hat and it’s a very powerful platform.

Boatingbaileys,

Many thanks.

As it happens, I already have a MacArthur HAT installed, and additionallyI have been a subscriber to your Youtube channel for around 6 months or so. I have just now seen a notification re the video. I will view that in the next couple of days (It is late here now in Australia (and hot), and I have a commitment tomorrow).

At the moment, my MacArthur HAT has limited (GPS and compass) sensors hardwired directly to the Pi5 simply routed through the HAT via GPIO pins. I am slowly working toward proving a concept for a slightly more complex project (though not unachievable).

I should be happy to download the latest OpenPlotter4 Beta image after I absorb your video.

Regards,
Loffy

I have now loaded the latest beta versions of the touchscreen openplotter app. It seemed to install okay.

Here is my problem:
- I have a Pi5, Pimoroni NVME, MacArthur hat, and a GPS/compass sensor wired up directly through the 40 pin connector (GPS TX and RX plus i2C for the compass). (Hat connections will happen later).
- I tested the "direct" wiring via the Linux screen app prior to downloading the OpenPlotter4 beta image. The GPS was working fine, and it displayed the correct location of the PI5 with a HDOP of 0.9. Given that the Pi was indoors I was happy.
- After installing OpenPlotter4 I cannot see the "boat" gps position on the chart. Moving the cursor shows a valid position on the toolbar at the bottom of the chart.

Any ideas?
Is the issue that the GPIO app is still under development?
Is there any documentation anywhere that can help (especially re GPIO)? I tried to lookup "read the docs" for version 3, but the GPIO and i2C section was very sparse; just placeholders.
Anything that I should do?
