Content Generate an LED blinking pattern for Persistence Of Vision (POV) from 24-bit bmp images. If the LEDs don't start blinking, chances are you have not named the image file correctly (Smiley.bmp), or your file is not 24 bit. For an example file, see https://git.card10.badge.events.ccc.de/card10/logix/blob/master/media/Smiley.bmp
