Thanks for making that clear for me.

In my eink animation demos, I only use pure black and white (which is MUCH faster than if there is ANY gray on the screen in the update area). I dither 65 shades of gray down to black and white (an 8x8 dither matrix has 65
dither patterns, including empty -- not 64).
In the newtrix demo, I also dither 256 shades of gray down to 16, as required by the eink hardware. On the K3 and earlier, each framebuffer byte holds two 4-bit pixels. On the K4 and newer, each framebuffer byte holds two COPIES of a 4-bit pixel. You can see how I handle this in the newtrix demo.
