Solarwind,

Your code is incomplete. You need to enable porta on change interrupt,
global interrupt,
disable analog, comparator. 



Using ccs compiler


void main()
{

   setup_adc_ports(NO_ANALOGS|VSS_VDD);
   setup_adc(ADC_OFF);
   setup_spi(SPI_SS_DISABLED);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC_NC_NC);// This device COMP currently not supported
by the PICWizard
   enable_interrupts(INT_RA);
   enable_interrupts(GLOBAL);

   while(true)
       {
                   SLEEP();
       } 

}



#int_RA               // porta change interrupt will jump here
void  RA_isr(void) 
{
// 
// put your code here to turn on off and after 10 seconds go to sleep.
}

Subject: [PIC] Interrupt on Change Pin

So I tried to get this to work. I have a PICKIT 2 with a LPC demo
board. It's a PIC 16F690 with LEDs on PORT C and a push button switch
on PORT A. Here's my code:

I'm trying to turn the LEDs on or off every time I press the switch.
How do I do this?
