My question is eigendlich simple but I'm unsure of the result.
Data sheet page 3: http://www.seeedstudio.com/document/pdf/WS2812B%20Datasheet.pdf
There are 400KBit / s indicated, right?
We are looking for the maximum number of LEDs at 5KHz writing speed.
I want to write a 3D image with a rotating display from LED's.
The display rotates at 3000 RPM = 50Hz
It should show 100 levels.
Thus 50Hz * 100 = 5000Hz = 5KHz, right?.
Now I would like to know how many LED's I can with an Arduino maximum control to get out whether these LED's überhaubt suitable.
According to my calculation, there are 80 LEDs. I am afraid but errors in the conversion!
In the worst case per layer all LEDs will be given new values. That is, Which is addressed with the 400 KBit / s 80 participants one after the other, right?
