Detailed Description

Flag to signal events between interrupts and the main-loop.

This class is quite handy when exchanging flags between a interrupt routine and the main-loop.

modm::atomic::Flag isrFlag;
 
ISR() {
    ...
    isrFlag.set();
}
 
function() {
    bool flag = isrFlag.testAndSet(false);
    ...
}
