Sometimes you just want to know and are curious: Is the 16 MHz clock on my development board (also known as a "Dev Board") really 16 MHz? In a previous tutorial, we showed two surefire ways to determine the frequency of a clock source. This tutorial outlines yet another way to be really, really sure. We've used the Nano Flip, a cheap near-field probe, and an oscilloscope with FFT capability to find out.
