Added pulses to openplotter-gpio v4.
Tested on RPI 4 & 5. It uses gpiod instead of pigpio or RPi.GPIO or GPIO Zero.
Only Seatalk1 is pending. When developing digital and pulse features, I have learned a lot about gpiod's Python binding and it is very capable. I am pretty sure we can also add seatalk1 using gpiod, but that will require a lot of testing and I do not want it to delay the release of OP4, so we will leave it until the stable version is released.
In addition to openplotter-gpio, updates to many other apps have been released. It is important to install them all from openplotter-settings and reboot or errors may occur.
There are big changes that make the system more robust and easier to debug. Many processes have been converted to systemctl services.
You will see that the "Rescue" option has disappeared from all applications. This is due to better management of this feature and now the system is more intelligent and can easily recover bricked systems. If your system does not boot or has entered a loop that makes it unmanageable due to a misconfiguration of any of the openplotter settings, insert the SD into another computer and add the following in /boot/firmware/config.txt:
OPrescue=1
OpenPlotter will start with all services disabled so you can fix any offending settings. When you are done, simply delete the new line in config.txt or set it to 0 and magically all the services will start.
It is taking longer than expected because the new Raspberry 5 is a powerful and rare beast and everything should work on Raspberry 4 as well. Thank you for your patience. Test and report as usual.

I'm a newbie and have a Pi 5 with a MacArthur HAT and I'm trying to get the usb gps a u-blox7 to work in Open Plotter 4. The gps is recognized in the Series section and it is in Signal K. It seems to have activity in but not activity out. The usb gps works in my other Pi 4 with Open Plotter 3. I'd appreciate any help anyone could give me with this. Thanks.

Updated openplotter-sdr-vhf v4
Uninstall the old version from openplotter-settings before installing the new one or run this in a terminal:
sudo systemctl disable openplotter-rtl_ais
rtl-ais has been replaced by the powerful ais-catcher. I do not have an SDR with me and it is untested, so there are bound to be bugs. Please try and report back.
@BlackSea, you did an excellent work with this package adding the webassets and the service, congratulations.

Sdr-vhf installs fine, but the service doesn't appear to start. When you select "Enable AIS Reception" the line doesn't go green like it used to. I'm inland with no AIS Reception, so I have no idea if the service is actually running or not.
