I’m planning on controlling 13000 WS2812 LEDs using 3 ouput expanders and a Pixelblaze V3. From the online documentation this seems to be possible as three output expanders can drive 38008=19200 leds. However, I am wondering how many pixel updates per second I can then expect using a PixelBlaze V3 to make a judgement on whether the update speed is sufficient or not. I am guessing the update speed also depends on the pattern used but a general indication would be nice. So my questions are the following:
- Could I get an indication of the amount of pixel updates per second possible using this setup, so how many times I could update the entire length of 13000 pixels per second?
- How could this update rate be improved? E.g. would adding more ouptut expanders help without increasing the amount of LEDs or should I use multiple PixelBlazes?
Thanks in advance for helping out,
