Description

We need code that will measure the fitness of a circuit trying to oscillate at a particular frequency.

This will need to measure rising edge signals during a given duration.

Contributor guide

Research direction
Implement a function to count rising edges within a given time window on a specified GPIO pin, then compute the frequency and compare to the target to derive a fitness score.
