Hi,
I used a 16x1 LCD display. When supply and ground is given and contrast is varied, then contrast of first 8 characters varied. Other characters remained in min contrast. When I tried to display some characters with a program, then also only first 8 worked. Then I thought it is a defective piece. But when I tried some other program, I have seen the other characters also working. What can be the probable reason? Can I conclude that it is a problem with my program? If so why only first 8 characters changed with contrast control? Can anybody help?
