Project: Hello guys I want to do a simple project. I want to display a photo image to a series of four NeoPixel NeoMatrix 8x8.
Question: I am wondering what is the best controller to do this, an Arduino or a Raspberry pi? and what type of software I can use to get the data to the Neopixel. Can you guys can recommend parts or a kit to get me going? Also any tutorials that can educate me about the subject can be the cherry on top. ;)
Thank you in advance! This place is amazing!

Re: Help with NeoPixel 8x8 and Images (Arduino or Raspberry
You need an Arduino to talk to NeoPixels.
The NeoPixel data protocol requires precise timing to distinguish between 0s and 1s. An Arduino can do that, but the RasPi runs Linux, which is a time-slicing OS. Each process gets about 100ms of runtime, then the OS suspends it, stores any relevant data, and gives the next process a turn. Having that happen in the middle of a data transmission would ruin the signal.

So now that I know Arduino is the way to go, does anyone know about a library to handle images with the NeoPixels?
Thank You
