Is your clock settings correct? Is your delay function provide the right delays?

1.I don't touch the delay function given by cytron.

Hey, thank you very much. I starts reading ,there was a problem on initializing the LCD.
Those who have experience on LCD has to prepare another tutorial on c compiler, most tutorials are on Hitech.
for more clarity on lcd initialization, i'll come back.

Hi Tech is C compiler

Hi thank you.
Look, when I send char('T') , the LCD display char"V".. this thing happens for alomost more letters. tell me why is this happening? am waiting ur replay.

Please post some photos.

my lcd 16x2 works but when i want to display like
TEMP A=22.3 it displays like this VGOR?22.3
T is changed to V
E is changed to G
M is changed to O
P is changed to R etc
so why is the lcd changing character TEMP A= into VGOR?

You use same coding with sample PR11?
If yes, maybe you are wrong wiring D0-D7 of the LCD.

Agreed with Shahrul, if the coding is same, should be the wiring. Photo of the hardware.

I am sure of the connection, the numbers are displayed well. the problem is on the characters.
instead of displaying TEMP A= value, it displays VGOR?value, as u look at the photo.
for the program,am using PR11 and I touched only
ADCON1 = 0b00011110;
ADCON2 = 0b10010100;
and i ignore CHANNEL1 SINCE I HAVE ONLY ONE LM35.
My device is p18f4520.

Can you clarify, which pin from PIC is connected to LCD? PORTD? From the wiring, it does not seem to be PORTD.

I am pretty sure there is problem at DB1 of LCD data port.
