If you replace this part

Code:

#define LCD_DB4 PIN_D0
#define LCD_DB5 PIN_D1
#define LCD_DB6 PIN_D2
#define LCD_DB7 PIN_D3

#define LCD_E PIN_A1
#define LCD_RS PIN_A3
#define LCD_RW PIN_A2

with this part

Code:

#ifndef LCD_DB4
#define LCD_DB4 PIN_D0
#endif
#ifndef LCD_DB5
#define LCD_DB5 PIN_D1
#endif
#ifndef LCD_DB6
#define LCD_DB6 PIN_D2
#endif
#ifndef LCD_DB7
#define LCD_DB7 PIN_D3
#endif
#ifndef LCD_E
#define LCD_E PIN_A1
#endif
#ifndef LCD_RS
#define LCD_RS PIN_A3
#endif
#ifndef LCD_RW
#define LCD_RW PIN_A2
#endif

you can include flex_lcd.c in all project easily.

to use:

Code:

#include "main.h"

#define LCD_DB4 PIN_C4
#define LCD_DB5 PIN_C5
#define LCD_DB6 PIN_C6
#define LCD_DB7 PIN_C7

#define LCD_RS PIN_B0
#define LCD_RW PIN_B2
#define LCD_E PIN_B1

#include "flex_lcd.c"

void main()
{
lcd_init();
delay_ms(250);
lcd_putc("\fExample");

while(TRUE) {
output_high(PIN_B3);
delay_ms(200);
output_low(PIN_B3);
delay_ms(1000);

}

Why use it ?

2. If you're a newbie and your board isn't configured to use the CCS driver, and you don't
know how to modify it or Mark's driver, then this driver can get you up running quickly.

LCD 2x16 Driver for MikroElektronika EasyPic v7 Board

I modified the following lines to make the LCD work with the EasyPic v7 and CCS C and is working great.

Code:

// These pins are for the MikroElektronika EasyPIC v7 Board

#define LCD_DB4 PIN_B0
#define LCD_DB5 PIN_B1
#define LCD_DB6 PIN_B2
#define LCD_DB7 PIN_B3

#define LCD_E PIN_B5
#define LCD_RS PIN_B4
// #define LCD_RW PIN_A2

// If you only want a 6-pin interface to your LCD, then
// connect the R/W pin on the LCD to ground, and comment
// out the following line.

// #define USE_LCD_RW 1

Thanks a lot PCM programmer.
