| multiple source files |

Hello !
How to compile with PCWHD (Version 4.073, 44201 ) multiple source files ???
Do I have a multiple compilation unit ? I can't use headers, PCWHD tell me blabla "Function used but not defined ..." !
| Code: | In main.c :
....
#include "LCD.h"
.....
In LCD.h :
#ifndef _H_LCD_
#define _H_LCD_
// prototypes ...
#endif
In LCD.c :
// functions .... |
I'm not using MPLAB. Just want to organize my code with 2 or 3 headers.
Thank's a lot ! |

The traditional way of using multiple source files with CCS, is to #include
them all in the main source file. Then compile the main source file. |

Thank's !
That's exactly what I'm doing ...
| Code: |
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.c"
void main()
{
char msg[20] = {"Hello !"};
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
LCD_INIT();
while(1){
LCD_GOTO(6,2);
LCD_PUT_STRING(msg);
delay_ms(500);
LCD_CLEAR();
delay_ms(500);
}
}
|
In LCD.h :
| Code: |
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "LCD.c"
#ifndef _H_LCD_
#define _H_LCD_
void LCD_INIT(void);
void LCD_SEND(char Octet, char INST_DATA);
void LCD_ENABLE(void);
void LCD_CLEAR(void);
void LCD_PUT_CHAR(char Car);
void LCD_PUT_STRING(char *ptr);
void LCD_GOTO(BYTE Col, BYTE Ligne);
#endif
|
In LCD.c :
| Code: |
#define LCD_EN PIN_C5
#define LCD_RS PIN_A5
#define INSTRUCT 0
#define CARACT 1
void LCD_INIT(void)
{
// initialisation de l'afficheur LCD controlleur KS0066U
delay_ms(40); //30 ms d'après datasheet
LCD_SEND(0x33,INSTRUCT); delay_ms(10); // Mode 8 bits
LCD_SEND(0x32,INSTRUCT); delay_ms(10); // Mode 4 bits
LCD_SEND(0x2C,INSTRUCT); delay_us(50); // Display ON, Cursor OFF, Blink Off
LCD_SEND(0x06,INSTRUCT); delay_us(50); // Entry Mode Set : Increment Ram, No Shift Display
LCD_SEND(0x0C,INSTRUCT); delay_us(50);
LCD_CLEAR();
}
// etc ..... all others functions
|
What's the problem ???? |

oops sorry, copy/paste error :
in main :
| Code: | #include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.h" |
in LCD.h :
| Code: | #include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "LCD.c" |
in LCD.c :
| Code: |
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h" |
test_lcd is my project ... |

In the CCS method, you don't include the header files such as test_lcd.h
in each module. Remember, it's effectively one big file.
If you have a header file which has constants which are used by other
include files, then just #include that header file one time, in the main
source file, near the top of the file. |

Thank you for your response !
So I try :
in main :
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.h"
in LCD.h : nothing ?
in LCD.c
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.h"
PCWHD don't compile ! Stop because didn't find lcd_init() ! |

I don't know exactly what you're doing, because all your files have
similar sounding names. 
See my post in this thread. It shows how to organize your main source
file:

my project's name is test_lcd
the main file is test_lcd.c :
| Code: |
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\test_lcd.h"
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.c"
#include "C:\Temp2\Stage PIC\TP\TP2_LCD\Corrige\LCD.h"
void main()
{
char msg[20] = {"Hello !"};
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
LCD_INIT();
while(1){
LCD_GOTO(6,2);
LCD_PUT_STRING(msg);
delay_ms(500);
LCD_CLEAR();
delay_ms(500);
}
} |
then only one header : LCD.h
| Code: |
void LCD_INIT(void);
void LCD_SEND(char Octet, char INST_DATA);
void LCD_ENABLE(void);
void LCD_CLEAR(void);
void LCD_PUT_CHAR(char Car);
void LCD_PUT_STRING(char *ptr);
void LCD_GOTO(BYTE Col, BYTE Ligne);
|
and the associated source : LCD.c
| Code: |
// Broches du LCD :

#define INSTRUCT 0
#define CARACT 1
void LCD_INIT(void)

LCD_SEND(0x2C,INSTRUCT); delay_us(50); // Display ON, Cursor OFF, Blink Off
LCD_SEND(0x06,INSTRUCT); delay_us(50); // Entry Mode Set : Increment Ram, No Shift Display
LCD_SEND(0x0C,INSTRUCT); delay_us(50);
LCD_CLEAR();
}
void LCD_ENABLE(void)
{
// Génère une impulsion positive de 50 µs sur la broche EN du LCD
// Le bus de données 4 bits est pris en compte par le LCD
output_low(LCD_EN); // LCD désélectionné
delay_us(1);
output_high(LCD_EN);delay_us(100); // LCD sélectionné

}
void LCD_SEND(char Octet, char INST_DATA)
{

// Si INST_DATA = INSTRUCT => Envoi d'une instruction
// Si INST_DATA = CARACT => Envoi d'un caractère à afficher
output_bit(LCD_RS,INST_DATA);

LCD_ENABLE();
delay_ms(1); // 2 envois séparés par au moins 40 µs
}
void LCD_CLEAR(void)
{
// Efface LCD, curseur retourne en haut à gauche
LCD_SEND(0x01,INSTRUCT); delay_ms(2); // > 1.53 ms
}
void LCD_PUT_CHAR(char Car)
{
// Affiche le caractère à la position courante du curseur
LCD_SEND(Car,CARACT);
}
void LCD_PUT_STRING(char *ptr)
{
// Affiche la chaine de caractères à la position courante du curseur
while(*ptr)LCD_PUT_CHAR(*ptr++);
}
void LCD_GOTO(BYTE Col, BYTE Ligne)
{
// positionne le curseur Ligne, Colonne

Your lcd.h file has the function prototypes it in. The compiler needs to
see them before it sees any calls to the functions. All you need to do to
fix it, is to change the order of your #include statements so the lcd.h
file comes before the .c file. Example:
| Quote: | #include "test_lcd.h"
#include "LCD.h"
#include "LCD.c" |

Also, change this to NOLVP. Do that in all your programs. You're not
using low voltage programming mode. |

OK thank's a lot it's working fine now !
I suppose it's the same way if I need more header files ...
Not a very standard C !
Bye and thank you ! |
