Separated into three steps:
1, KEY1 press output LED0=1, after let go LED0=0;
Output after 2, KEY2 press LED1=0, let go on LED1=1;
3, KEY3 press, can use the timer operation LED lights flashing, timing for a period of time

CodePudding user response:

If (KEY3==1)//assume that button press 0
{
LED0=KEY1;
LED1=KEY2;
}
The else
{

LED0=LED1=~ LED0;
Delay_ms (500);

}
