Hd44780 Lcd Woes..., lcd_driver.h Options

[Gues7]

I have been trying to get the LCD Driver routines working on the PIC16F684 (Which is properly defined in the project file) however, when executing the lcd_setup(), lcd_clear() and lprintf() functions I get errors, the lcd_driver.h file is definitely included. I have also checked the lcd sample project to ensure I wasnt missing any other header or library files from the project, I dont believe I am...

The code I am using is:

CODE

/*

BoostC HD44780 Interface

*/

#include <system.h>
#include <lcd_driver.h>

//#prgama CLOCK_FREQ 8000000
#pragma DATA _CONFIG, _BOD_OFF & _MCLRE_OFF & _PWRTE_ON & _WDT_OFF & 0x3FFC & _HS_OSC & _CP_OFF & _IESO_OFF & _FCMEN_OFF & _CPD_OFF
/*                        1            2            3            4            5                6            7            8            9            10

#define LCD_ARGS     2, 1, portc, trisc, porta, trisa, 0, 1, 2
/*                   1  2  3      4      5      6      7  8  9

    5: USE PORTA FOR CONTROL REGISTER
    6: THE TRISS ADDRESS FOR PORTA
    7: BIT NUMBER OF CONTROL PORT FOR RS
    8: BIT NUMBER OF CONTROL PORT FOR RW
    9: BIT NUMBER OF CONTROL PORT FOR EN */

void main(void){
    cmcon0 = 0;        //DISABLE COMPARATORS
    adcon1 = 14;
    porta = 0;        //CLEAR PORTA
    portc = 0;        //CLEAR PORTC
    
    //char myString[5] = ['G', 'u', 'e', 's', '7'];        //THE STRING TO BE OUTPUT
    int i;
    
    lcd_setup();    //ENSURE EVERYTHING IS READY FOR THE LCD
    lcd_clear();    //CLEAR THE LCD
        
    for(i=0; i<=4; i++) {    //LOOP THROUGH THE ELEMENTS IN THE ARRAY
        lprintf("Gues7");    //AND PRINT THEM TO THE LCD
    }//rof
    
    while(1);
    
}//naim

And the errors I receive are:

At the minute, I am just trying to learn all og the functions of the BoostC libraries so in the event of having to use them, I can do it in a snap, any help on the matter would be much appreciated.

Thanks


Also... just an FYI for Dave, I got an error regarding _INTRC_OSC_NOCLK when I was using it in my device configuration... so I read the value out of the header file and that works without a problem... it seems the compiler had not got _INTRC_OSC_NOCLK defined, although it IS in the header file, and it IS spelled correctly (first thing I checked)

Here is my basic template when working with the 684 chip.

It may be of some help to you......
