Detailed Description
DebounceIn adds mechanical switch debouncing to DigitialIn.
Example:
#include "mbed.h" #include "DebounceIn.h" DebounceIn d(p5); DigitialOut led1(LED1); DigitialOut led2(LED2); int main() { while(1) { led1 = d; led2 = d.read(); } }
- See also:
- set_debounce_us() To change the sampling frequency.
- set_samples() To alter the number of samples.
