Description:
An update of https://flows.node. red.org/flow/fa6e4749ff7f9067fd6b5330bc54f9e3 to use more applicable RPi resource sources. My first exercise with Node Red. Dashboard colour selection looking to a future Elecraft colour themed dashboard for my station.

It sounds like the EEPROM on the Pi4 needs repaired, it is a simple process and here is link to a Youtube video describing how to do that.

On the Pi4 you can create an image by using the built-in system backup and copier utility on the Pi's desktop, It can easily?copy to a USB thumb drive or to a USB SDCard adapter.? This will also?let you shrink the size of the SDCard to a smaller?SDCard as long as it is big enough to fit everything?on it. Just make sure when you plug in the backup SDCard it is mounted and should?show up on the pi's desktop then bring up the Backup utility.? I have done this Many times now and have not failed.

You will need to update the board¡¯s firmware.
Also check the SD card if is not corrupted.
Here is the pre compiled binaries

You might tinker with the width setting and spread it out wide. Here is an example of what I'm working on right now. It's a full on radio system controller for a DXpedition station in a box, called a RIB. ()
I have used only three "tabs", but have adjusted them to be very wide, 27 in this case.
I have leveraged two things that aren't mentioned much on this list or in youtube vids.
One, is use the layout editor on the dashboard / Layout tab. Use it to adjust the visual node positions. You can drag the visual representations of each node to any position, and resize them at the same time.
It's not all good, as the NR developers have an auto-place algorithm that screws up your perfect layout each time you add another visual element. So, get all of your buttons/text fields etc in in play, before bothering to place them in the desired positions. You will see what I mean, the first time it happens. I keep screen shots of the layout grid handy, so I put everything back in place without too many expletives.
Also, I use the "Allow group to be collapsed" option. That puts a little arrow in the corner, and allows show/hide of the whole tab.
I've attached shots of the Dashboard and the layout editor, and how to get to it. The idea is the top portion contains the most used controls, and the second and third levels are collapsed until needed.

Were you able to resolve your problem? ?If you need a zoom, for help, we can arrange.
As for downloading new Raspberry Pi images, I have had good results using the official Raspberry Imager. ?Download the app to your PC or Mac and burn your desired OS image directly to a SD Card. ??
Using the Raspberry Pi Imger, you can pre-configure the SSH and other settings, by following these instructions for "Advance Options:

I wanted to thank Dave WO2X for all the work he did on the QST article for NodeRed that just was published.? ?Nice job!!!
With that article, there is a reference to this group, so I expect a bunch of new members.
As a reminder, we are hear to help, mentor and collaborate?all members.? And, to our new members, welcome.? We are happy to help you.

I really wish Node Red would put in better dashboard support.? Lining up groups and spacing them where you want is not obvious.? The current setup is great if you have one row of groupings, but once you get to two rows, it can be a challenge to make it look nice and neat for those of us with OCD.. :)?
They should move to a better WYSIWYG screen for arranging groups and your dashboard nodes.

I haven¡¯t tried it but the default dash is 48x48. You can change that. Also saw an interesting alternative for a dash for those that know web page programming. Looks a lot more powerful with full css support. I have to find the link and post it.?
Having a more graphically oriented dash similar to the HAOS dash is something that intrigues me. I wrote one web site using Wordpress for NJDXA.org (we¡¯re the second call district incoming QSL bureau). It is not professionally done but allows our subscribers to purchase credits to get their QSL cards.?
Maybe some in the group are talented with web programming and would like to contribute some dashboard ideas? I¡¯ll find the link.?

Re: Initialize relays at RasPi startup
Domenick For my GPIO based relay flow, to "initialize" a relay on Node-Red restart, just change one of the "Test" inject nodes to inject one second after start. ?This will position the relay and store he result in context memory. ?I show below an example of using the "false" or open the relay, as an example. Of note, one of the issues with Raspberry Pi GPIO pins, is the first initial "state" on boot up is undetermined, that is the purpose of waiting one second to initialize the relay. ?Keep in mind, as a result, the relay position could be anything for the first second before the "initialize" inject node fires off.

Re: Initialize relays at RasPi startup
For automatic just use an object node to send Boolean false. Connect it to all the Pi relay GPIO outs. Set the inject to send once after 5 second then interval to never. When you start the Node Red server it will initialize the relays after 5 seconds.?

Re: Serial Control of the ERC-4 Rotator Controller
Hi Nick.? Yes I did add a map like Dave did.? I have uploaded my most recent versions of Rotator_20210806.json and Map_Interface_20210806.json to my wb0smx_Flows/ERC_AzMap directory (Note** Moved to !1! Flows by Type/ROTORS/ERC Controller/ERC_AzMap_wb0smx) in the files of this group.? The Rotator flow replaces the original ERC_Control flow that I posted earlier.? But you can change the name to whatever you like.
The two flows are designed to interface with each other through the link nodes.? I modified and simplified Dave's Map flow for my purposes.? It still shows the current beam heading and target heading (for 20 seconds after setting target), and allows for clicking on the map to set a target bearing.? The Rotator flow still has buttons for shortcuts to specified bearings, as well as free form input of bearings in text and numeric fields.
Good luck and enjoy...

Does anyone have a working flow to control and load frequency data to an Alpha 87a amplifier??

Re: Serial Control of the ERC-4 Rotator Controller

thank you for the flow, did you add an Azimuthal map .
I was trying? to add a? map like? Dave did, but his flow required? PstrotatorAZ . any ideas ?
I works great ,?
