Two things right off the top - typically you need to wait a bit before calling lcd_init() (those things are slow to wake up - 500ms or so is a good start). Second, you are updating the display at a 10 hz rate - most LCD displays (and your eyes) can't handle that. You should not update a LCD more than 2 or 3 times / second.

Delete this line:
| Quote: | | #define LCD_DATA_PORT getenv("SFR:PORTD") |
Then read this thread about putting the #define statements for the pins
above the #include line for lcd.c:

You have not really told us what the problem is.
Is the PIC working at correct speed (Blink a led at 1 Hz to check)?
Has the screen got black(or whatever colour screen you have) boxes, or is it blank?
Also, get rid of the following. It should not make a difference, but you don't need it unless you are using FAST_IO.
| Code: |
set_tris_d(0x00);
set_tris_c(0x00);
set_tris_b(0x00);
|
Then, put another delay_ms(1000) before the lcd_init() line. You can play around with this later once you know it works. Some displays like a delay before init, some like it after and some like it both ways... |

I'm trying to get any figure on the screen. but code not working, anyway I will add delay_ms(1000); before LCD_init(); hope work this time thanks.
| Code: |
#include <18f4550.h>
#fuses HS,NOWDT,NOPROTECT,NOBROWNOUT,NOLVP,NOPUT,NOWRT,NODEBUG,NOCPD
#use delay (clock=20M)
#define LCD_ENABLE_PIN PIN_B5
#define LCD_RS_PIN PIN_C0
#define LCD_RW_PIN PIN_B4
#define LCD_DATA4 PIN_D4
#define LCD_DATA5 PIN_D5
#define LCD_DATA6 PIN_D6
#define LCD_DATA7 PIN_D7
#include <lcd.c>
void main ( )
{
setup_psp(PSP_DISABLED); // PSP birimi devre dışı
setup_timer_1(T1_DISABLED); // T1 zamanlayıcısı devre dışı
setup_timer_2(T2_DISABLED,0,1); // T2 zamanlayıcısı devre dışı
setup_CCP1(CCP_OFF); // CCP1 birimi devre dışı
setup_CCP2(CCP_OFF); // CCP2 birimi devre dışı
delay_ms(1000);
lcd_init();
delay_ms(1000);
while(1)
{
lcd_gotoxy(1,1);
delay_ms(1000);
printf(lcd_putc,"Hi baby=");
delay_ms(1000);
}

Seriously, 'step back'.
Have you actually verified your processor is running at all?. At the correct speed?.
The _first_ thing you will see advised here for a lot of threads (and add this one to the list), is to perform the simple 'flash an LED' test. LED wired onto one pin (with a suitable current limiting resistor), and a minimum program to flash this at a regular interval like 10 seconds.
This needs to work, and be flashing at the right speed _before_ you make any attempt to go further in programming.
It verifies:
1) Power is correct.
2) Reset circuit is correct.
3) Clock oscillator is running.
4) Clock is running at the right speed (time the flashes).
5) That you are programming the chip correctly.
6) That the chip itself is working.
Only once this is working right, progress to trying to do anything more complex. |

you 're master, ı will do what you ever you said
1) Power is correct. >>>>>yes correct
2) Reset circuit is correct. >>>>>yes
3) Clock oscillator is running. >>>>>measured 20mhz
4) Clock is running at the right speed (time the flashes). >>>>ı dont under stand what is mean
5) That you are programming the chip correctly. >>>> ı will check again
6) That the chip itself is working. >>>> ı will check |

You were told to write code to flash an LED at a fixed rate.
Time the flashes with your watch!
Do not proceed beyond this point until it works correctly.

Normally the first program you code for a PIC is the '1Hz flashing LED' program.
Simple hardware...just an LED and resistor on an I/O pin,usually one you're not going to use later....
Simple software....
main()
do
output_high(LED);
delay_ms(500);
output_low(LED);
delay_ms(500);
while(true);
probably a typr or two...
the idea is to turn an LED on/off at a known rate, 1 HZ is 'nice'.
this program will confirm 'fuses' are set correctly,hardware is OK, etc.
also I'd use fuse PUT instead of NOPUT.
The Power Up Timer allows the PIC to startup more reliably.

Yes.
You missed the point about my question. Testing with a meter/scope, does not prove that the PIC is getting the right voltage in the right place, or that the oscillator actually runs (when the scope is not there), and that the chip is running at the right speed. The simple flash an LED test, does.
There are two things I suspect.
First, that you are actually running at 5MHz, not 20MHz. You don't have a CPUDIV1 fuse, and I think that the default for this is CPUDIV4. So with a 20MHz crystal, the chip will be running at 5MHz. The LED test would have found this at once.
The second is that the chip may not be starting at all. Is MCLR pulled high?. Again the default is for this to be enabled, since you haven't got it turned off, and the chip won't run unless the pin is pulled up.
Then as a separate comment, temtronic has pointed out NOPUT. The power up timer, is _recommended_ if you are running with a crystal. Should only be disabled, if you are using the RC oscillator, or two speed startup (starting on the RC, and then switching once the main oscillator is running). |

no ı found problem but the problem is so holy ı guess computer thought like holly any way
ı'm gonna break these computer there is no hope for me, ı can not work really easy code, pls someone help me how ı define that holly "glcd_pixel" because of if ı define these word, problem solved anyway ı will break these piece of junk. thanks
error: undefined identifier --glcd_pixel
| Code: | #include <asd.h> // ossicilator is true
#include <graphics.c>
void main()
{
setup_timer_3(T3_DISABLED | T3_DIV_BY_1);
while(TRUE)
{
glcd_pixel(0, 0, 1);
glcd_line(0, 10, 10, 20, 1);
}
}

sigh.... 
Delete this part of your post, you are not allowed to reproduce it on the internet!
Besides, we all do own the compiler and already have this file. Removing it will make your post smaller and easier to read. |

sorry for that admin
I will check myself and I add a led pin_b7
| Code: |
output_high(pin_b7);
delay_ms(500);
output_low(pin_b7);
delay_ms(500);
|
It's working but lcd problem go on. |
