Hi all
I am facing problem in 16* 1 lcd , GDM 1601 . The first 8 characters are working . and remaining 8 characteres are not working.

To solve this problem i used this trick:

1) moving the cursor at 9th character by using its address
as the first 8 characters and last 8 characters address range ( ie 00 and 40 as starting address) differs . but it doesnot solve the problem.

In full contrast the first 8 charactter are displayed with more brightness. whereas remaining are not. I am facing the same problem in the 5 lcd .


DO U HAVE ANY IDEA TO SOLVE THAT PROBLEM

Thanks for reading my problem.
 

remaining 8 characteres are not working because it die. I have same problem with my LCD 1602A
 

Most 16*1 displays are configured to work as 8*2. So write as on the second line to acces that characters.
