Hello

I am using the microchip 44- pin demo board with a pic16f887.

Now I am trying to create an interrupt using the switch.

I start by using the example code cButton.c given with the evaluuation board,







#include <pic.h>
#include <htc.h>
/* cButton.c - Simple C Program to Turn on an LED when Button is Pressed

This Program is a modification of "cFlash"

RA3 - Button Connection
RA4 - LED Positive Connection
RA5 - LED Negative Connection

__CONFIG(INTIO & WDTDIS & PWRTEN & MCLRDIS & UNPROTECT \
& UNPROTECT & BORDIS & IESODIS & FCMDIS);

int i, j;

main()
{

TRISD=0x00;
RD0=1;
PORTA = 0x3F; // All Bits are High
while(1)
{
RD7=RA3;
//if(RA3==0)
// RD3=1;
//if(RA3!=0)
// RD3=0;
}
CMCON0 = 7; // Turn off Comparators
ANSEL = 0; // Turn off ADC
TRISA4 = 0; // Make RA4/RA5 Outputs
TRISA5 = 0;

while(1 == 1) // Loop Forever
{

if (0 == RA3) // Set values using "if" statement
{
RA5 = 0;
}
else
{
RA5 = 1;
} // fi
} // elihw
} // End cButton







but when I want to build the program- I get an eror:


Error [192] C:\Users\Matar\Desktop\MPLAB_projects\motor1.3_button\main.C; 36.1 undefined identifier "CMCON0"


Since this is anexample code, I can expect it to work without errors.
can someone help me find a solution to my problem?

There is no CMCON0

only CM1CON0 CM2CON0 CM2CON1

CM1CON0,7 = 0 is what should turn it off

or C1ON_bit = 0
