With added feature to capture signals and measure frequencies, we had to make a small change to the “Pin” library. The new feature uses hardware timers (very accurate) but those timers are also needed for PWM. The new pin enum makes it easy to see what pins support Capture and what resources are shared.
@Gus_Issa - will this also allow us to use the hardware timers as counters? You mention measuring frequencies, but what about just counting pulses that are not necessarily regularly spaced.
