this is going to take a while

It looks like you have things a bit tangled up to put it nicely.

Manyof the undefined symbols should have been defined in the processor header file which is obtained via

#include <p18cxxx.h>

Then there is this sort of error
:65:Error [1109] type mismatch in redeclaration of 'send_cmd'

It looks like you have an improperly setup project.
Others may disagree but I suggest you zip up the entire project and include it as an attachment. That way we can try to build the project and see where you have gone wrong.

Thanks. I think I'll try to untangle it a bit myself before I do that though. I haven't actually spent that much time on it. I only get about an hour a night I can work on this stuff, and thats not uninterupted, so its slow going for my projects. I'm sure I did setup the project wrong. The blog I got it from didnt really say how to set it up. Though I guess if I was expierienced with C18, it would probably be pretty obvious.

Triode if you put all the file in one folder and add just the .h files it should work. From what you
posted it's adding the wrong ones.
And LCD.c and delay.c
C18 has a lcd.h and delay.h of it's own I would bet it using them.

sorry, im a little confused by what you wrote at the end. What did you mean by "And LCD.c and delay.c " was that in addition to the things I should put in the folder, or the wrong ones?

Now that I can see the source it is clear I suggested a different definition for byte

Change
#define byte unsigned char;
to
typedef unsigned char byte; // no # char

That may fix the
Error [1109] type mismatch in redeclaration of 'send_cmd'
sort of errors.

To fix the undefined symbols try replacing
#include <p18cxxx.h>
with an include of the exact file you need.
If you chip were a 18F1320 you would use
#include <p18F1320.h>
Just adjust the number to fit you chip.
See how far that gets you.

Just had a play with this and I had to make a few changes to main.c to get it to compile.
Code:
#include <p18cxxx.h>
#include <stdio.h>
#include <delays.h>
#include "delay.h"              //added
#include "LCD.h"

#pragma config OSC = INTIO67    //Internal oscillator
#pragma config IESO = OFF
#pragma config PWRT = ON
#pragma config BOREN = OFF
#pragma config WDT = OFF
#pragma config MCLRE = OFF     //MCLR is disabled
#pragma config LVP = OFF

/*                              //removed
void delay1s() {
    Delay10KTCYx(200);
}*/         

//User defined putc for user defined output stream
void _user_putc(unsigned char c) {
    send_data(c); //Send character to LCD
}

void main() {
    OSCCON = 0b01110010; //8 MHz
    TRISC = 0x00; //PORTC is all output
    stdout = _H_USER; //Set to user-defined output stream via _user_putc

    lcd_init(); //Initialize the LCD
    send_cmd(0x0C); //Turn off cursor

    set_cursor(1, 1); //Set cursor to row 1, column 1
    printf((far rom char*)"Hello!"); //Print "Hello!" to the LCD    <---changed

    set_cursor(2, 1); //Set cursor to row 2, column 1
    printf((far rom char*)"HD44780");                 // changed

    while(1) {
        delay250ms(); //Scroll the display 1 character right every 250 ms
        sc_r();
    }
}
Mike.

what is

#pragma config OSC = INTIO67

My spec sheet for 18F1320 doesnt show there being a 67. Just 1 and 2

Thanks for the suggestions, It may be a while before I can implement them since when I get home tonight I'm going to start moving, haha. It may be monday evening before I get to work on my hobby any more. Oh well, thats life when you have to work isn't it?

I set MPLAB to use an 18F2620 so I didn't have to go through the code and change PORTC to PORTB. The config labels vary between chips and the 2620 uses INTIO67.

Yeah, I noticed that I will need to change that too. I'm doing this all on a junebug for now, So idealy I'll be setting it to ports that are easily accessable on the pin strip also.

Here the whole thing I think it will run on the junebug it built all right and I change it to use PORTB on a 18f1320 I didn't try it but it looked good
Mike I'm getting better now I know I need some of these {} LOL
I lied I will run on PORTB of a 18f1320 you'll have to do some more adjusting for the junebug

How would you do a low order on PORTA you RA1 to RA4 for data
and RB1 could be Enable, RB3 could be Read/write, and RB4 could be Register select
But I don't see how you could do the low order with out RA0
You change this but how I don't no
Code:
void send_nibble(byte b) {
	LCD_PORT = (LCD_PORT & 0x0F) | (b & 0xF0);
	strobe();

well, I dont know, I have bigger 18F chips if necessary.

Maybe this would work Mike or 3v0 maybe let us no
Code:
void send_nibble(byte b) {
	LCD_PORT = (LCD_PORT & 0x1E) | (b & 0x1E);
	strobe();
It'S in the LCD.c

Close,

LCD_PORT = (LCD_PORT & 0xE1) | ((b & 0x0f)<<1);

Note, E1 - not 1E.
