Here's code for scrolling text across a matrix

Patterns and Code

I’ve been playing with my PixelBlaze and a couple of 8x8 matrices this afternoon. I was getting the same issue as @Kenzillla. For me, changing line 100 from this:

if (renderBuffer[row][col]) hsv(0.07, 0.5, 1) // warm white

to this:

if (renderBuffer[row][col])
  hsv(0.07, 0.5, 1) // warm white
else
  hsv(0, 0, 0)

Did the trick! Hope this helps.
