The python code uses two vectors of 20 values to draw its diagram (the C code has both 8 values commented out or 20 values). It is hard for me, though, how to devise a drawing based on those HEX values and how to avoid ghosting.

I would advise strongly to update the code on github in order to make it easier for one to draw in binary, like a sprite, and a proper cleanup function. If I try to do any change on the values, the display stops responding and I have to do a full power off.
