I'm trying to figure out how to use a nokia 5110 lcd which uses the PCD8544 controller. Datasheet here.
After reading the datasheet I can't seem to understand what are the Temperature Coefficient/Bias Voltage/Vop.
How do I choose their values and what do they do ?
One at a time: temperature I you ever used an LCD at freezing temps you would realize that the crystals move slower. Now, I would guess that the value chosen would be based on the actual display purchased. It might be a trial and error thing and best done at the lower temperature.
