for loop error

[kshitijnov]

I am trying to implement a situation where when the switch (connected to porta pin7) is closed the led connected to port b blinks 4 times. the program itself has no error but when i try to simulate it on proteus it doesnt work. here is the program

unsigned int n= 0;

void main()
{
CMCON0 =0x07;
TRISA= 0b10000000;
PORTA =0b00000000;
TRISB = 0;
PORTB = 0;
if(Button(PORTA,0,0,1))
{
for(n=0;n<8;n++)
{
PORTB=~PORTB;
Delay_ms(300);
}
}
}

[checker]

if(Button(PORTA,0,0,1))
{
for(n=0;n<8;n++)
{
PORTB=~PORTB;
Delay_ms(300);
}
}
}

maybe try this:

Code: Select all

     while (1){
     if(Button(PORTA,0,0,1)) {                                                         
          for(n=0;n<8;n++){                                                          
               PORTB=~PORTB;                                   
               Delay_ms(300);
              }
          }
     }
}

you are not in a while loop so it does not check for more button pushes so unless you have the button pushed at startup, nothing will happen because it is a one shot.
