I need to display a still image (just the same grey color all over, so no need for difficult calculations what to display where) using only an Arduino Duemilanove (ATMega 328) and a Sharp LCD panel (datasheet)*.
However the datasheet assumes a clock speed between 50 MHz and 80MHz, way to much for a simple Arduino. What will happen if I try to use the monitor at a much lower clock rate? Remember, I try just to display a uniform, non changing color. Will the display begin to flicker? Also, what might happen, if I fade the color?
* It is part of a project to demonstrate what's possible using an Arduino and old electronics. So I restricted myself not to use any other complex bought electronic (your definition here). A small IC may be in order, a completely new board not.
