Hi, well I've been downloading games to my calculator(yes, class is boring) And I noticed this one game, they have grayscales, various levels of gray, and I asked myself how do they do this? Since the calculator only operates at 14.7Mhz I see some interference and stuff, so maybe to make grayscales you have to turn the pixels on and off really fast with software generated PWM?
Right now I only have character LCDs, I really want to get a graphical one soon to play around with.
Oh, and I can't find the source code for the game.
