Hello,
I am potentially going to be measuring a square-wave signal (.5 to 5KHz) with a Teensy 3.6 and possibly later a Teensy 4.
The low end of this range is a major control input for my project, as such I would prefer to use FreqMeasure to have the best resolution possible below 1KHz. The signal will also have control implications at the high end of the range as well, but actualization requirements up there aren't nearly so stringent.
It doesn't seem like the reference pages have been updated recently, perhaps not significantly since the release of T3.1, and I wanted to clarify the theoretical limits of the FreqMeasure library on the newest Teensy models. The reference page states:
Can this be interpreted to mean that a T3.6 at factory clock speeds running FreqMeasure can theoretically read 180MHz? Or perhaps it would be an octave of this clock speed. Anyway, any input on this point would be appreciated.

At higher frequencies, the short time can only be measured at the processor's clock speed, which results in limited resolution.
