i'm using 8051 mcu to do some tests. i'm trying to use two input for two push buttons and two outputs for two Leds. SW1 = push button 1 SW2 = push button 2 LED1 = led1 LED2 = led2
for example -if i push S1 the Led1 will glow continuously. -if i push S2 the Led2 will glow continuously.
These two command works independently.
So here what i tried: only S1 and Led1 are working. Please help, thank you.
#include <reg51.h>
sbit S1 = P2^0;
sbit S2 = P2^1;
sbit Led = P1^0;
sbit Led2 = P1^1;
void main()
{
S1 = 1;
S2 = 1;
while(1) // For ever
{
if(S1 == 0) // if press Push button
{
Led = 0;// ON LED ( active low )
while(S1 == 0);// Wait here for release of push button
}
Led = 1;
}
{
if (S2 == 0)
{
Led2 = 0;
while (S2 == 0);
}
Led2 = 1;
}
}
