Hi ..
I want to write program for check button pressing (Counter)
In case of Press button has 5V
In case of Not Press button has 0V

I can use ADC for detect it but the problem is when I press hold button my program will increase 1 (by non stopping.)

SO How can I do even I press hold the button the must count only 1

 int i=0;
 char txt1[4];
 long adcVal;
 void main ()
 {
    portc=0;
    TRISC = 0b00000001;
    trisa = 0xFF;
    trisb = 0x00;
    ADCON1 = 0x87;
    Lcd_config(&portb,1,2,3,7,6,5,4);
    Lcd_Cmd(LCD_CURSOR_OFF);
    Lcd_Cmd(LCD_CLEAR);
    Lcd_Out(1,1,"Test Counter");
    i=0;
    IntToStr(i,txt1);
    Lcd_Out(2,1,"Count:");
    Lcd_Out(2,8,txt1);
    while(1){
    adcval = adc_read(0);
    if(adcval >512)    [I]// ~ 2.5V[/I]    
    {
      Delay_ms(500);
      i = i++;
      IntToStr(i,txt1);
      Lcd_Out(2,1,"Count:");
      Lcd_Out(2,8,txt1);
    }
    }
}

please help
thank you!!

Why dont you use a GPIO input line of the micro instead of the analogue input?

why you are using ADC for this purpose. this can be easily done without using ADC.
