OLED 96x96 greyscale image

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

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