Hi guys,
I'm looking to embark on a pretty big project. I want to create a 128x128 LED display using individually addressable LED strips. Obviously 16,384 LEDs is a massive amount. I've done a bit of research and have a general idea of one possibility of doing it, but I'm not sure if it is the best way. I want to have a solid plan before I start anything.
I was originally thinking to split the display into four 64x64 chunks that each are controlled by a teensy 3.2 with a OctoWS2811 adaptor since the maximum LED count for 60Hz is 4416 LEDs according to the product page. But then I wasn't so sure where to go from there in terms of connecting things together, and what would be actually pushing the data to the teensies to display.
I wanted to know if the OctoWS2811 would even be the best way to address this many LEDs. I saw an example project that used 4320 LEDs with the OctoWS2811, so it looked like I might be able to scale up to 16,384. I've seen some people talk about using FastLED, but I wasn't sure about the differences between it and octo. I also didn't know if I should use just a board like the teensy 4.0 since it is much faster than the 3.2.
If there are more powerful chips that can address this task much better, or easier to use when if I want to add wireless functionality, that would also be nice to know about.
I should mention this is for a club and we already have a tiny 7x14 LED display made that uses a teensy LC and that works nice. All the processing is done on the chip such as generating stuff to show on screen. This bigger project I feel will be much different.
Overall I'm just trying to get some research so I'm not running into a wall. Thanks guys.
