Fork of DebouncedInterrupt by
Example code:
#include "DebouncedInterrupt.h" DebouncedInterrupt up_button(USER_BUTTON); void onUp() { // Do Something } int main() { // Will immediatly call function and ignore other interrupts until timeout up_button.attach(&onUp, IRQ_FALL, 1000, true); // Will call function only if button has been held for the specified time //up_button.attach(&onUp, IRQ_FALL, 500, false); while(1) {} }
