off grid in germany

Last night I swaped the system between my "WinuAE" and the old "Server" Intel D525MW, so the self 3D printed housing matches it's purpose now
(red case with fan on the top with the C= logo is now the WinUAE machine)

Then I took an old SSD with an old backup of my W7 system and surprice it didn't crash on booting (as the hardware changed, some ICH driver family...)
but the VM can't start the Linux VM I have created on my server.
W7 is 64 bit, the Linux VM is 64 bit ... and that's the point. I need V-hyper / virtualisation, that the board can't provide.
After many searches in the web I found out, that I only could run a 32bit VM Linux ... ok. Was a try.
I keep the VM running it on my Server, that runs flawless (knocking on wood? haha)

There is one more thing that could come in handy ...
These RS485-Network adapters ... https://amzn.to/3Lc2sOw ... so if I understand it correct, it simulates a COM port on the machine and builds a "bridge" over the ethernet to the RS485
May be next month.


Edit:
Have now VM installed on the Lattepanda, takes forever to start but if it is once stared, it runs well.
Parallel runs the battery monitor software and the dos batches. Still have 5 pages open (3 tablets, 2 on my PC) and they load with is lightly more delay compared to my server that is standing upstairs close to me, but acceptable.
So I think about a housing for the Lattepanda and leave it there for the next time.
(The PI was never meant to run the logging and serve more then one open page but it kept up very well until I went crazy haha)

How is that rs485 different from just using one of the $1 converter boards ? You get the rs485 data to a com port -  then can do what ever you want to with the data.

I am not sure how these protocolls work.
I was also thinking about using one of the small converter boards and wire them to the PI, so I have not the USB stack "overhead" the cpu has to handle with.

I guess it made everything easier and that all could gone another direction if they populated the serial connector at the BMS. But it is what it is now

If someone made an interface already that works on the rs485 then it is pretty easy.  They pretty much all use modbus.
I think you probably saw the videos I made where I used rs485 to esp8266 . I used it because the smarter people had made the modbus programs work so I only had to figure out how to connect it all together. Nice thing is the pi gets all the data via it's built in wifi so no wires going to it other than the power cable.

Thanks, Larry

yes

One day we will trip over what we are searching today



BUT I have found out now, why the pages sometimes don't load or load extremly slow ...
After that now, the answer was so easy and obvious ... but you have to find it
If more then one page is trying to load the data text files, then a file can be blocked while it is loaded from another page ...
So I added two lines to my batches, in it the data text file is copied to the web share folder and then it is also duplicated.
Each page loads it's own text file now. Did this also with the current.txt.
Now it is all running great, like I wanted.

I also mounted the Lattepanda on it's "new" cooling plate and hung it by it's cables in place
