Hi,

I noticed that your SeeedGrayOled.drawBitmap() method only works for blackAndWhite-Images, not for the 16 steps of greyscale the Display is able to show.

Please, tell me how to get a greyscale image on this screen, as this is everything I bought the thing for…

I’ve seen examples via processing, so it can not be that hard. Any clues/hints?

hi~ it’s easy to make a black-and-white image in you PC, you can use windows(assume that you use Windows system) paint, and save it as binary bitmap :smiley:

of curse, you can use Otsu binarization method to handle a image with color.
