WebParameters: pin ( DigitalInOut/function) – the DigitalIO or function to debounce. short_duration_ms ( int) – the maximum length of a short press in milliseconds. long_duration_ms ( int) – the minimum length of a long press in milliseconds. value_when_pressed ( bool) – the value of the predicate when the button is pressed. WebParsing on a ESP32 at 200 Mhz CPUclock with Micropython takes about one millisecond per event, and even less if you use the reuse_event_object of the MidiFile object. Times with CircuitPython on a RP2040 are similar. With the reuse_event_object parameter set to true, CPU overhead should be about 15% lower, and less heap is used.
