Hi guys
I am working on a project, it's a battery power device. So the device needs to sleep as much as possible. And I don't want to use delay within interrupt to debounce.
The interrupt is triggered by a push button. Thanks guys!

Code:
uint8_t global_var_state_1;
uint8_t global_var_state_2;
uint8_t global_var_state_3;
while(1)
{
//state machine bases on
//input from global variables
sleep();
}
void interrupt buttonPress(void)
{
//debounce (how? don't want to use delay here)
if (button_press_is_valid)
{
//change values of global_var
//for state machine.
}
}
