Long press the key on remote PIC
PostPosted: Sun Sep 05, 2021 4:41 am     Reply with quote
This is a code that works well.

Is there a way to define a function by long pressing the remote key? But I need a way to long press key on ir remote ?
For example after 3 second pressing in case 16.

Code:

nec_remote_read(){
  unsigned int16 count = 0x00;
  unsigned int8 i;
for(h=0;h<2;h++){
  SET_TIMER1(0); //9
  while(!input(IR_Sensor) && (count < 0x251C))
    count = GET_TIMER1();
  if( (count > 0x251B) || (count < 0x2134))
     return FALSE;
  SET_TIMER1(0x00); //4.5
  count = 0x00;
  while((input(IR_Sensor)) && (count < 0x1388))
    count = GET_TIMER1();
  if( (count > 0x1387) || (count < 0xFA0))
    return FALSE;
  for(i = 0; i < 32; i++){  //32READY
    SET_TIMER1(0x00);
    count=0x00;
    while(!input(IR_Sensor) && (count < 0x28A))
    count=GET_TIMER1();
  if( (count > 0x289) || (count < 0x1F4))
      return FALSE;
    count = 0x00;
    SET_TIMER1(0x00);
  while((input(IR_Sensor)) && (count < 0X708))
      count = GET_TIMER1();
  if( (count > 0X707) || (count < 0X190))
      return FALSE;
  if( count > 0X3E8)                                 
      bit_set(ir_code, (0X1F - i));                     
  else                                             
      bit_clear(ir_code, (0X1F - i));                 
  }
  return TRUE;
}
 }

In the manual, in the FAQ sections, there's a 'timed keypress' chunk of code.
it 'looks' for a pin status AND < certain timout value. Pretty sure you can modify to make it work as you need.

How do I wait only a specified time for a button press?
The following is an example of how to wait only a specific time for a button press.



#define PUSH_BUTTON PIN_A4

int1 timeout_error;

int1 timed_get_button_press(void){

int16 timeout;



timeout_error=FALSE;

timeout=0;

while(input(PUSH_BUTTON) && (++timeout<50000)) // 1/2 second

delay_us(10);

if(!input(PUSH_BUTTON))

return(TRUE); //button pressed

else{

timeout_error=TRUE;

return(FALSE); //button not pressed timeout occurred

}

}
....
