Question regarding fast pins
Posted: 27 Aug 2020 15:27
I have set up a nice little working FLiRS based wallswitch using a Z-Uno. My code is available at https://github.com/anonymous-one/zuno-flirs-wallswitch.
I have a question regarding fast pins:
1) I tried setting up pins 17-20 as fast pins. I could only get 17 to respond correctly. Is it possible to only have 1 fast pin at a time?
2) Is there a point of using fast pins on a wallswitch? I am assuming the loop cycles at least a few times even though wallswitch clicks are fairly quick, but maybe the 'bring up' time for a fast pin is longer then any benefit you get from them?
3) Can INPUT_PULLUP pins be fast pins?
