Electron CPU usage

[TiemenMoesker]

I researched the BCM2835 today if there where any known problems with it. Turns out there are, I just didn’t understand any of them. English is not my first language and I am a kinda new to the whole Raspberry Pi stuff and all the programming around it.

@TiemenMoesker I’m sure thats not the reason for it, but it was worth trying it as a possible fix

You have a link for that?

@Mykle1

Let me try, appreciate the help dude. Best forum i’ve ever been on. Problem is not solved yet, but I am happy there are some more brains in de game to help us out.

I have installed the MMM-Earth module and the same thing happends.

That makes perfect sense. If your Pi struggles with the simple compliments transition then it would certainly have trouble with MMM-EARTH. I’m even more sympathetic now because that’s my module! :-(

This is what I found just typing in Rapberry BCM2835.
Not sure if this has anything to do with this problem tho.

I read through both links. I don’t see anything that applies to this problem directly.

BCM2835

For my two raspi3:

Both of them are the BCM2835 Hardware-Versions. First BCM2835 has the problem, the other BCM2835 hasn’t. Wow… :-D

@djsunrise19

So the CPU usage doens’t spike with animations?

Not so high like my first one (100% permanently), about 50-60%. Here is a picture from my ATB, that arrives today. Naked installations, standard config / css / modules. 75% peak. Bad.

@djsunrise19

Sorry to hear that man. I can get mine replaced for free, but I think I get a Pi with the same hardware

Well, there goes my theory, if the installations are exactly alike.

Oh hell no. This issue gets more mysterious by the day!

That is even high, in my opinion, based on my results

[bhepler]

For what it’s worth:

Hardware: BCM2835
Revision: a02082

And I do not have the problem.

It definitely helps. I think we can now eliminate the possibility that the difference in hardware has anything to do with this issue.

Thanks!

@Mykle1 Yes, you’re right. Yesterday I installed the new raspbian stretch and all MM tools manually, uninstalled electron and installed the @beta (1.8.). I wanted to give that a try. But still the same.

As you can see, the problem is there , less or more, over months (with that 50-70% cpu usage). With 2-3 animations at the same time my raspi struggles (raspi2 and raspi3). But a few days ago, there were an github update. Since that update my mirror is unusable. Why?

git pull && npm install

says, that there was a change in the readme file only. But it doesn’t seem so.

Since you are addressing me directly, I will answer, directly and plainly. I don’t know why your mirror is now unusable. I joined this topic because I was/am interested in determining why some people have this problem and others don’t. We have eliminated some possibilities but not all. I can sympathize with you, having struggled with problems of my own. There only seems to be a handful of people experiencing this problem. I am not one of them but I am trying to determine the cause using what little knowledge I have.

@Mykle1 I’m sorry. There is nothing directly to you. I only try to write as much as I find out in that situation to know as much as we can. I’m very thankful that you’re trying to help (and didn’t have our transition problem).
