[AVR] LCD interface, nothing in 2nd line

[WidElectronics]

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.

 

[S.P.S]

Post the code so tht we could help you. it sounds like a software error

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 !
