Hi, I have a strip with 100 LEDs. I want to make three 3x3 matrices with it, where each slot in a matrix consists of 3 grouped leds. So I need 27 LEDs for one 3x3 matrix and overall 81. The remaining LEDs can stay inactive.
How can I configure this setup? Which settings are required in the 2D configuration?
When I would not require grouping I would define it as 9x3 and then make three segments with 3x3.
Virtually, it should be a 9x3 matrix, but physically each point of the matrix should consist of three LEDs.
Any ideas?
Thank you
Chris
Hello,
no reply yet? Is my question not understandable? Should I refine somehow?
its unclear.
you can just do a normal 9x9 matrix and enable grouping.
Thank you @dedehai for the reply. I want to achieve the schematic from the graphic. As said in the initial post: three 3x3 matrices. Every x marks a LED. I am not sure, how a 9x9 matrix would fit this pattern. The LED strip would at first run in traverses through one entire matrix and then to the next …
I don’t know how to do this.
one option is to get 12V strips that already have groups of 3 or us some LED-map tricks, not sure it works like this though as the mapping is for virtual pixel to physical pixel and not phyiscal to virtual (which is what you want to do), at least last time I checked. Someone else more familiar with mapping could know.
OK. Thank you.
I need the features 2D matrix, segments and grouping altogether. I might have a look at the source code for the LED mapping feature. Maybe there is a way to enhance it.
I keep the thread open. Maybe someone else finds something for a solution…
Cheers
