Hello all,

I am facing a problem in my LCD interface code...(with avr Atmega128).
I have written code in AVR Studio4. My code is builded successfully. When I compiled no errors found.
To simulate I am using ISIS protel software....- For design I have used avr Atmega128 and LM016L(16*2 LCD).
To write in first line 0x80 command is used and I am getting output in first line of lcd. I have used 8bit 2line in my code by sending command 0x38 to LCD....
For the second line the command to be sent is 0xC0 and I have used this...still not getting... :-?

Is there any other reason for not getting data on 2nd line of LCD!!!???

Hoping for the help and guidance.....

Thanks in advance.:grin:
 

post your simple LCD code or Proteus simulation file.
 

you can try delay after sending commands and try for data also.
and after posting code problem can be solved immediately.
 

hello,

are you sure LM16L is a 2 lines LCD ?
or LM1602L
it is allways better to test in real world !
