#int_rb and One button for different functions
PostPosted: Thu Aug 12, 2010 9:17 am     Reply with quote
Hi Friends!! Can anybody help me with example for #int_rb and #int_timer1 interrupts for making one button with different function? (push without holding ->increment var.count, push with holding 1-2second ->clear var. count)

Thanks before Smile

Let see example and you can modify. It work fine but may not be expert code.
Code:

#int_RB                         
void menu_isr() {
if(!input(PIN_B4)) RB_ready=1;
}
void main(void){
...

...
...

while(true){
 if(RB_ready){
   
     while(!input(PIN_B4) && (++timeout<350000)); //PRESS LONG APP 3 SECOND 
     beep(); //call Beep routine
                                if(input(PIN_B4))
                                {
                                          MENU=!MENU; // Menu is int1
                                          // Loop Menu if press not longer than 3 second
                            if(MENU==0){ //do something// } 
                            if(MENU==1){ //do something//}
                                                         
                                         
                                }
                                     
                           else {  //Press more then 3 second do this
                                   delay_ms(200);       
                               
                                         //do something//
                                       timeout=0;
                                }
               } //end else 
                   
                                      RB_ready=0;       
           }//end rB ready

 ...

...
}//end while
}//end main
