| [Help] LCD.c and flex_lcd.c |

Hi everybody!
I'm using PIC16F887 and LCD 16x2.
I've problem: use flex_lcd.c is OK, but use lcd.c of CCS library the LCD display not right (#).
My code here:
| Code: | #include <16F887.h>
#fuses INTRC_IO, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#include <lcd.c>
//#include "flex_lcd.c"
#define LCD_DATA4 PIN_D0
#define LCD_DATA5 PIN_D1
#define LCD_DATA6 PIN_D2
#define LCD_DATA7 PIN_D3
#define LCD_ENABLE_PIN PIN_A1
#define LCD_RS_PIN PIN_A3
#define LCD_RW_PIN PIN_A2
//==========================
void main()
{
lcd_init(); // Always call this first.
while(1)
{
lcd_gotoxy(1,1);
printf(lcd_putc,"Hello you");
lcd_gotoxy(1,2);
printf(lcd_putc,"PIC16F887");
}
} |
I use internal crystal.
I did not edit #define in LCD.c file and CCS version is 4.105.
Thanks for all! |

If a file looks for #define statements, you need to put them above
the #include statement for the file. Example:
| Code: |
#include <16F887.h>
#fuses INTRC_IO, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#define LCD_DATA4 PIN_D0
#define LCD_DATA5 PIN_D1
#define LCD_DATA6 PIN_D2
#define LCD_DATA7 PIN_D3
#define LCD_ENABLE_PIN PIN_A1
#define LCD_RS_PIN PIN_A3
#define LCD_RW_PIN PIN_A2
#include <lcd.c>
