Next point button in freeboard vs KIP?

@David Godin I understand boat/pin functionality doesn't exit yet. I want to work on that, so I'm gathering ideas for how to do that development. Having simple buttons to mock up a UI would be useful.

Next point button in freeboard vs KIP?

For my usage, I'm not using an AP. I guess I could just use the AP widget if it has such a button, but I was hoping to be able to use the generic kip push button so that I can mock something up, as I think this will be useful for other mockups in want to do (e.g. ping start boat and pin). But if the AP widget has buttons that do this, then at least I can look for a code example to follow.

Anyone found reliable 12v Raspberry Pi power options for boat use?

I found an entirely separate 5v supply for the screen, and I'm still getting the message? So that is just a pi-5, an NVMe SSD and a keyboard dongle. So the warning cannot be due to power demand, but some aspect of the supply?

Next point button in freeboard vs KIP?

@David Godin ah node-red! I've seen that mentioned a few times but don't yet know what that is. I'll investigate. Non super elegant will do whilst I'm working out how to get what really want ( which is ultimately to get sailracer app for functionality). Note that I'm currently defining waypoints and routes in openCPN and doing a GPX export/import. Now that's something that is screaming for better integration.... But at least it works for now (and my C skills are rustier than my JavaScript).

Next point button in freeboard vs KIP?

@AdrianP yeah I can see how to do it programmatically, as that is obviously what freeboard does. But I was hoping to be able to mock up a UI using existing kip widgets before committing to a custom widget (graphical elegance is not my strong point). So my main question really is about how to use a kip push button to do anything, so I can focus on a server side plug-in whilst working out what I really want to do.

Next point button in freeboard vs KIP?

I'm not using an AP. I'm setting up for racing and working on a plug-in that will give me TWA and AWA for the next leg. Ultimately it might need widget support, but I'm trying to work out if I can use standard kip widgets to drive it whilst I learn exactly how things work and what I want

Anyone found reliable 12v Raspberry Pi power options for boat use?

Having read this discussion, I ordered an SH-RPi for the system I've just started building. It arrived today, but I'm getting a warning that it cannot supply 5V at 5A and the screen often does not turn on. My stack is (top down): * SH-RPi v2 * Pi-5 * USB bluetooth with long range antenna * USB keyboard/mouse dongle * USB micro speakers * NVMe base board with 512GB SSD * 7" Pi Touch Display v2 When powered on the screen often does not power up, but the LEDs on the SH-RPi and Pi-5 all do the right things and it looks like it is running OK. If I disconnect/reconnect power to the screen it eventually turns on, but there is a warning on the top right of the desktop saying words to the effect of "the power supply cannot provide 5V at 5A, so peripheral usage will be limited"? I've installed the software and it appears to be working fine (shutting down the Pi when power is removed). Can this SH-RPi-2 power a Pi-5 with boards/peripherals I have (if not, then it is not really useful)? I have put the jumper in place to allow 2.8A draw. Note that I have tried powering the display from the 5V at the end of the 40 pin connector (as done without the SH-RPi) and from the 5V supply from the SH-RPi (of course the power cable was not long enough by default!). Also any idea how when this low power mode is triggered how I can reliably get the display to power up?
