ı can work this project with both "//#include <HDM64GS12.c>
//#include <graphics.c>" but when ı define lcd.c, there is no life on screen
| Code: |

try this....
add
delay_ms(500);
THEN
lcd_init();
LCD module take some time to get 'organized' before you ( the PIC) can properly access them.
also
delete the
use fast_io(a);
unless YOU specifically control the tris registers, the PIC won't operate the I/O port the way you think it will. Probably 99.99% of all PIC code cut doesn't really benefit from fast_io(),at least none of the 'simple' programs.

I move the pinout lcd.c also there are no warning or error. |

lcd_init();
delay_ms(500);
needs to be other way...
delay_ms(500);
lcd_init();
also have you got the LCD wired correctly according to the lcd.c driver pin configuration ?
also do you have a contrast pot on pin 3 of the LCD. should have about 0.5V on it.

ı tried before lcd_init but not working
ı connect pins ı checked again what ı define;
#define LCD_ENABLE_PIN PIN_B4
#define LCD_RS_PIN PIN_B2
#define LCD_RW_PIN PIN_B3
#define LCD_DATA4 PIN_D4
#define LCD_DATA5 PIN_D5
#define LCD_DATA6 PIN_D6
#define LCD_DATA7 PIN_D7
last thing ı'm using 20k pot pin3, pin 18 and 5v, this process working graphics.c but not working lcd.c there is a little tiny point but ı didn't figure out |

Hi,
Dude! You seem to be throwing mud at the wall and hoping for something to stick.... 
LCD.C is for a CHARACTER LCD display, while HDM64GS12.c is for a GRAPHICAL LCD. Do you know the difference??
Post a link to the LCD that you are using. Right now you seem hopelessly lost.......
John
PS Proteus or real circuit??? |

may ı cry aaaaaaaaaaaaaaaaaaaaaaaa
any way last question
++++++++++++++++++++++++++++++++++ in this point how ı show the sicaklik value on screen ı tried glcd_text57 but ı couldn't thanks

Hi idris,
I really don't think you have any idea at all what you are doing, you are just 'tweaking' everything in order to get *something* to work..... Moreover, this is almost certainly a Proteus exercise......
Anyway, if you hope to learn anything at all, looking graphics.c and try to determine what the glcd_text57 needs to work properly. Then look at the CCS manual and take a look at sprintf function.

get back to basics !!
get rid of all code EXCEPT
LCD specifics like driver and init functions
ADD delay_ms(500);
BEFORE lcd_init();
do a simple print to lcd like 'hello world'. There are examples here and in the examples folder that CCS supplies
so
recode/recompile/retest/report back...
show program and results....
we'll go from there.

Jay,
I don't think the OP has any real hardware, because the code that has been posted seems to randomly switch between character display code and graphics display code. More importantly, I don't think the OP has any real idea of what they are trying to do. I think we are just chasing a homework exercise here by a student that hasn't really bothered to figure out what they are trying to accomplish. It's the old 'ask first, think second'.... Right now, all we have is a bowl of Jello......

I search ccs manual and prepare again code:
| Code: |
while(1)
{
bilgi=read_adc();
delay_ms(100);
voltaj=(0.0048828125*bilgi)*1000;
sicaklik=(voltaj/10)+2;
delay_ms(500);
sprintf(text,"%5.2f", sicaklik); <<<<<<<<<<<<<<<< holy code
glcd_text57(1, 1, text, 1, ON);
delay_ms(1000);
}
|
but ADC not working, lcd screen (128x64) show me "2.00"

This is a very small program and you have to learn to debug it yourself. If we give you the solution now you will never be able to find a bug in a more difficult program.
To help you we have to know if you are using a simulation program or real hardware. This has been asked before but you never answered it. We suspect you are using Proteus simulation software.
For debugging you will have to go through the program step - by - step. For this you can use a hardware device called 'In Circuit Debugger' like the Microchip ICD2 or PicKit. Or you can use the free Microchip software simulator in MPLAB.
Only when you go step-by-step you can see the values of all variables and figure out which line is going wrong. This is how professionals work. If you want to become a professional then learn to use these tools.
Don't just 'think' about how the program works but use the tools to measure the values, then you will 'know' where things go wrong. |

You should 'play computer' !
Manually, with pencil and paper do the operations...
your code...
voltaj=(0.0048828125*bilgi)*1000;
sicaklik=(voltaj/10)+2;
first you multiply by 1000
then divide by 10
The +2 is 'odd'..same number as displayed....
You should printout 'voltaj' to see what it is.
