Answer When using the LCD simulator or connecting an LCD panel, the LCD driver clock should be setup to be as close to 4kHz as possible. For example, if fsys=4MHz, the clock source(fs) = fsys/4 = T1 = 1MHz. Therefore the LCD driver clock should be setup to be fs/28 = 1MHz/28 = 3906Hz. If this is done the LCD DISPLAY should display data normally.
