Seatalk 1 on Raspberrry Pi 5 working

[Sailoog]

Thanks to Adrian (Wegmatt) who did some excellent coding work, we now have Seatalk 1 up and running on Raspberry Pi 5.

To use it on OpenPlotter v4.x.x, make sure you have at least these versions installed:

• Signal K sever 2.11.0
  
• openplotter-signalk-installer 4.2.0
  
• openplotter-gpio 4.2.10
  

The Seatalk 1 connector on the MacArthur HAT should now also work fine on the Raspberry Pi 5: https://macarthur-hat-documentation.read...atalk.html

Post here any issue please.

Awesome Job Guys!!

I was so happy to hear this, I went and installed my RPi5 on the boat:

ATTENTION an update to the latest kernel broke Seatalk1 on Raspberry Pi 5: https://github.com/SignalK/signalk-server/issues/1788

It has an easy fix but it has to be applied to new versions of the Signal K server and the openplotter-gpio app. We will publish here when it is solved.

Updating to SK 2.11 fixed the issue.
Thank you

Also updated openplotter-gpio to fix the same issue in digital and pulses features.

Make sure you have these apps updated:

• Signal K sever 2.11.0
  
• openplotter-signalk-installer 4.2.0
  
• openplotter-gpio 4.2.10

New user, sorry to bother you but, in my case, the Seatalk 1 to Signal K connection is not working doing a fresh installation on a Raspberry Pi 5 with:

Signal K Server version 2.12.0
Signal K Installer version 4.2.0
OpenPlotter GPIO 4-2-10

I believe I have done everything by the book, in fact if I use a small python script I am able to see a nice stream of Seatalk messages coming through my pin 4

In the Signal K Dashboard I can see this error message:

Traceback (most recent call last) File "<string>", line 299, in <module> ValueError: invalid literal for int()with base 10:


Any idea?

Thanks in advance.

Are you using Raspberry OS or an OpenPlotter image?

I got the latest OpenPlotter image from the Open marine website and did a fresh installation.

To be absolutely sure about my setup I downloaded an Openplotter V3 image and installed it on a Raspberry Pi 3.

With the same optocoupler wiring I was able to connect my seatalk instruments to the Signal K server at first try.

So I suppose the problem must be something related to the combination Openplotter V4 + Raspberry 5.

Thanks for your interest.

After checking with the developers in their Discord channel it seems that there is a bug: the default value of the GPIO pin in the Data Connection setup interface is 4. If you dont change it there is a problem in the configuration and you get errors.

You must change to a different GPIO pin number, for example 5, save the change and restart Signal K.

Then change again to pin 4, save and restart, and voilá!
