IMPROVEMENT LED bins - scan once, output for more than one LED (Support for longer strips)

As I noticed that running many LEDs can cause hyperion to simply crash (I just can not get it to run smoothly), I came up with an idea that should ease the lifes of many.

If you would be able to sum up many LEDs into "bins" where the colors are only calculated per bin, thus making 2 or more LEDs identical. This will cause Pi's to consume way less CPU for longer strips. I am sure there is already a way to do color calculation not per each LED with intense json scripting.


What do you think?

 

How long is “long” ?

I’ve had a 16x16 led matrix running with no issues scraping the screen.

I’ve also had 750 leds driven by the python effect engine (but I can’t remember if I every tried screen grabbing with it )

 

I just checked the source - hyperion.ng can “clone” an led by index number.
So you can:
- define led 0 with its hscan and vscan
- define led 1 as “clone 0”
- define led 2 as “clone 0”
- define led 3 with its hscan and vscan
- define led 4 as “clone 3”
- define led 5 as “clone 3”

 

And here’s the commit that added it:
https://github.com/hyperion-project/hyperion.ng/pull/157

 

So this actually works in hyperions standard version, or do I need a special one?

Edit:
Tested it, doesnt work in my version, the clones just stay black,

 

Nope - the explicit clone is only in Hyperion.ng

In classic 2 (ore more) leds can have the same hscan and vscan I don’t think there’s a performance benefit
