i try to simulate the code below using A1 as input if the input of A1 is high the pin A2 will blink once if A1 input is low A3 will blink once

here is the code:

#include <16F84a.h>
#use delay (clock=4000000)

#fuses HS,NOWDT,NOPROTECT
#use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2)

void main()
{

while(1)
{
if ((input(PIN_A1)==1)
{output_high(PIN_A2);
delay_ms(50);
output_low(PIN_A2);
delay_ms(50);
}
else
{
output_high(PIN_A3);
delay_ms(50);
output_low(PIN_A3);
delay_ms(50);

}

}

}

i try to simulate using ISIS lite, but the only blink A3 no matter what input i insert...any idea what's happening ?

i insert the 16f84a, then i insert a logical input (0 or 1), then i run but the A2 condition never met ..why ?

maybe because pin_a2 is taken by the #use rs232?

i ran this on my 16f84a and it worked. you were missing a ) after the if statment coz you had 3 ( and only 2)

i tried something else because it was behaving strangly, like work fine but then stick on one for a little bit then work fine agin but it didnt help.
