= RGB64x32MatrixPanel on ESP32 =

For a friend I'm making a RGB LED panel, and need to pull some social media numbers and display them on the panel.

For this I wanted an ESP32 so it could do HTTP REST calls over wifi. I came across this library for efficiently talking to HUB75 RGB panels on an ESP32:
