Hey guys,
so i got this wall in my room just standing there, doing nothing.
Now i thought i’d throw a visualizer up there, with a matrix shown in blue and actual strips shown in green in the attached picture. I expect it to be around 600*300, but only filled with some of the pixels. I hope to drive it with an ESP8266, as i have one lying around.
Now i got two questions:
can i define stips that are horizontally/vertically placed to be a matrix?
can/should i exclude the empty spaces from being calculated, to save on processing power?
I’ve never worked with fastled before, so if you see something flawed with the concept or got other pointers i would be glad to hear it.
Thanks!
@Gibbedy_G The visualizer would be some program reacting to music played in the room.
Along the green lines lines are the “active” pixels of the (blue) matrix.
I’m working with my second language here, so i’m sorry for not being fully clear
@Daniel_Gunsch ok i think I understand.
When I think about how I would do this I run out of memory instantly… I think your visualiser software must know about the layout of your matrix strips and calculate what to turn on.
What will make a key difference is if you are trying to run standalone from something like a Teensy, or just as a bridge. There are examples of how to take lighting protocols like dmx and e1.31 and output the LEDs. You would then use lighting control software to drive the matrix and map each led to the matrix in the lighting app (e.g qlc+)
Hey, thanks for your answers @Will_Tatam and @Gibbedy_G .
I guess i could also run this from a raspypi with an ESP attached.
After looking into qlc+ i’m getting a little pessimistic on this project as the full matrix would be 180k pixels and qlc+ cannot even map all of those within DMX limits.
So, am i dreaming too big here or do you think it can be done?
EDIT: The reacting-to-music thing would be a bonus. To even have some nice effects flow fluently over the wall would be great.
@marmil Yess, that looks promising! I’m gonna get me some basic testing equipment to get into that. And, if I may, get back to you in a little while with additional questions
However, now i found this:
Could this be hackable to contain a onward direction (x+/x-/y+/y-) and a separated offset for x and y?
Or would i not win anything with this?
Again, thanks for your help as this is my first time with fastled and i’m not much of a coder in general
