DotStar Poor Brightness Control

by rellis on Fri Mar 09, 2018 3:14 am

Individual pixels are still very bright when set to near 0;

Setting a pixelcolor to {1,1,1} provides a very bright pixel. Am I doing something wrong? Should that be almost not visible? Or does the DotStar just not have very much per pixel brightness control?

It seems impossible to smoothly fade a pixel to 0 without a pop. When it goes from {1,1,1} to {0,0,0} it goes from bright to nothing.

It's only 8 bits per color, so the values are 0-255 for each color.

Unfortunately as the dotstars are extremely bright for their size that translates to the gap between off and "1" as being rather high.
