Hi, I am trying to get an LCD display with a built-in Sitronix ST752 controller going and not having much luck. There are several capacitor that can be setup to generate the LCD voltage with a multiplier of 2 to 8 The hardware has been setup for a multiplier of 4. I'm completely unclea as to how you would determine what multiplier to use. The controller has reference voltage generator, a voltage follower, and a booster. I don' know which of these I need to enable (looks like all for interna operation with only a single 3.3v supply). There is also an interva digital pot for setting of the display contrast. I've not been able t get any voltage out of the power supply section. I do seem to be gettin a status readback from the display. Can anyone help clear this up for m a bit? The processor being used is a PIC18F4620 BTW.
