The Pixel Framebuf library makes drawing to a grid of NeoPixels or DotStars as easy as writing to a display. The library has all of the drawing functions of the original framebuf library, including the ability to draw lines, circles, rectangles, and text.

This library can be used on a wide variety of NeoPixel and DotStar LED layouts including with flexible and non-flexible matrices, NeoPixels strips laid out by hand, or FeatherWings. This library has been tested to work with both CircuitPython Microcontrollers and Blinka on the Raspberry Pi.

One of the huge advantages that using NeoPixel and DotStar LED matrices has over the standard RGB LED matrices is that they only use one or two GPIO pins. The Pixel Framebuf library gives you the simplicity and control to make use of these matrices to display data in a meaningful way in much the same way that you can on RGB matrices.
