adc errors in mplab pic16f877

hi there i wrote this program so that wuth a simple potentiometer i will see results on leds but it is giving me erros. can someone help me plas? thanks
code is below with the errors at the end.


#include <htc.h>
#include<pic.h>

void delay(unsigned char itime);

void main (void)
{
TRISAbits.TRISA=0; //RA0 input for analog
TRISC=0xC0H; //RC0, RC1 are set as outputs
TRISD=0x00; //D is set as output

ADCON1=0b10000000;
ADCON0=0b0000001;

while(1)
{
delay(100);
ADCON0bits.GO=1; //start converting
while(ADCON0bits.DONE==1);
PORTC=ADRESL;
PORTD=ADRESH;
delay(100);
}


void delay (unsigned char itime)
{
unsigned int i,j;
for(i=0; i<itime; i++)
for(j=0;j<200;j++);
}

Advisory[1] too many errors (21)

what is glcd???? is it any other files that you forgot to include in this file

no no, forget about that. its only the name of the project cos i was gonna write something for a grpahic lcd but then i changed my mind and did the adc instead. its only a name. but i dont know exactly why i have all these errors. i followed an example from a book and almost copied it word by word.

Hi friend

#include <htc.h>
#include<pic.h>

Click to expand...

Don't include this both file
because pic.h is already included in htc.h

so only htc.h is include

Try this,
Good Luck

why use both header file???????

is this the first error that shows .. its compiler problem.. either it is out of date or licence is over.

same. nothing changed :s

i changed it to #include <pic16f877.h> and the only error it gave is:Error [141] C:\PROJECT\GLCD.as; 1.22 can't open include file "pic16f877.h": No such file or directory

so that means i have to leave it #include<htc.h>??

make it #include<pic.h>

i always feel htc.h is a better option than pic.h when using hitech C.........
