Figure 4 shows some example flowcharts for some common button debouncing algorithms. Figure 4 – Button debounce implementation flowcharts Tip #6 – Now, write the code Writing the embedded software ...

Note that successive calls to the debounce routine move it from the just-pressed transitional state into the “button is down” state where it will spend a lot of time when someone’s mashing it.

Debouncing button or switch inputs on microcontrollers can be a challenging problem for those first starting to program these devices. Part of the reason for this difficulty is that real-world butt… ...
