Button function

[ascomm]

Code: Select all

void blinking()
{
   GPIO.F1 = 0;
   Delay_ms(800);
   GPIO.F1 = 1;
   Delay_ms(200);
}

void poweroff()
{
   GPIO.F1 = 0;
}

void powersaving()
{
   GPIO.F1 = 0;
   Delay_ms(8);
   GPIO.F1 = 1;
   Delay_ms(4);
}

void bright()
{
   GPIO.F1 = 0;
   Delay_ms(4);
   GPIO.F1 = 1;
   Delay_ms(8);
}

void main(void)
{
  unsigned short b;

  TRISIO = 1;
  CMCON = 7;
  ANSEL = 0;

  GPIO.F1 = 0;

  b = 0;

  while (1)
  {

    if (Button(&GPIO, 0, 5, 0) && b < 3)
    {
      b++;
    }
    else if(Button(&GPIO, 0, 5, 0) && b == 3)
    {
      b=0;
    }

    if (b==3) blinking();
    if (b==2) powersaving();
    if (b==1) bright();
    if (b==0) poweroff();

    /*switch (b)
    {
      case 0: poweroff();  break;
      case 1: bright(); break;
      case 2: powersaving();  break;
      case 3: blinking(); break;
      default: asm nop;
    } */
  }
}

Is there someting wrong with this program because it doesn't react button presses at all?
Can I use Button with same port which has output functions?

Hi ascomm,

You might try to have the ANSEL and the trisio settings at the Beginning of your code.

Doesn't help...
Program runs just the blinking() function constantly. Or I think it is running that because the RA1 is blinking but nothing else happens.
