Standalone rendering function

Hi. I need a rather small (code size) function / library to render a 64x64 multidimensional array (informations for every pixel) to a 64x64 hub75e led matrix. No graphical functions, like shapes or text needed, only the renderer, with full collor support. I scanned the smartmatrix code alot, but I couldnt extract my needed code.

I would appreciate some help.


Take a look at the FastLED_Functions example, which efficiently writes RGB data to the background layer.

SmartMatrix::GFX will give you a 2D array in which you just write your 24bpp pixels and do matrix->show() when done.

or more specifically

or simpler even, you can simply write to
matrixleds[matrix->XY(x,y)] = 0xFFAA55
