im always come out with errors using this C language coding for my pic18f452.....
can you help me to correct the errors....
#include <p18f452.h> //We're using the PIC18F452
#include <delays.h> //We'll need the delays library
void main(void)
{
TRISA = 0x00; //Initialize these Ports as Outputs
TRISC = 0x00; //This one too
TRISD = 0x00; //This one toooo
PORTA = 0x00; //Initialize PORTA...so the LED is off
/*
The PIC is connected to the Motor Controller via 6 pins

PORTCbits.RD0 = 0; //Brake Off

}
This coding actually to run a dc motor clockwise and counterclockwise....and also to control the speed....
I receive error for this line...PORTDbits
mentioned 'undeclared identifier'....
and also error for this line...#include <delays.h>
can you help me to correct the errors....
