I just hooked up my first 20x4 LCD. Ideally I would like to update one of the lines at a pretty high rate (every 33ms). However, it seems as though the display does not redraw fast enough (time it takes to update a single character).
I changed the logic to do the updates less often but the effect is the same. I guess I was expecting more “snap” with the redraw.
Is this expected for this kind of device?
