  • @Gordon, this new option is absolutely great news. I was looking for something about detectable minimum pulse width, but could not find it. Now we know another tech spec detail and dependency on power (saving) mode.

    I do not really care about the reported pin state, because when push comes to shove, I control it anyway myself. Important is that the pulse comes thu. This even helps for complicated debouncing.

    @billsalt 's addition of the flip flop that cuts the frequency in half and watching both edges is really a great solution pattern.

    The most though I liked the test driver. When I suggested it a while ago I was not sure if it is possible to create such a short pulse... now it's proven (I got the idea from another test driver implementation when exciting an LC circuit for figuring the resonance: Espruino controlling LC resonance experiment in HAM Radio class. In this example I was not sure how high the frequency could go. Since for finding the resonance frequencies, excitement works also just 'provoking' along the harmonics...).
