WebOct 23, 2024 · What’s actually being compared here is polling vs. interrupt control of an I/O process. In polling, the CPU program samples a status signal periodically and takes action in response to its state. With interrupt, the status pin state change causes the CPU execution to branch to an interrupt service routine, which in turn takes care of the I/O. WebDebouncing in analog hardware can achieve results that you cannot achieve by a switch "observed" only digitally on a periodic basis by polling or even by hardware pin-change events. But you can do "well enough" for all intents and purposes, digitally. Almost no one these days uses external analog debouncing solutions.
