I have a 2X16 lcd display conected to an arduino uno. I wanted to display different custom charactures in each display blocks. I could only show 8 of the 32. When i looked it says only 8 custom charactures can be used.
So i stuck with the 8 charactures. Problem is the LCD flickers where the the charactures are. If i use normal letters there is no flicker.
I have stuck i video showing the problem on youtube LCD trouble - YouTube
