Problem description: Use timer input capture to measure frequency, input signal frequency range 50K-500K; detection object: square wave; use the official input capture example (see the TIM routine in
The two examples that come with edgeBorad, image classification runs smoothly, and now let's run "image calibration" also known as "object detection". This is an application for detecting screws and n
