Design of a high-precision phase difference measurement circuit based on FFT and STM32

Overview

Two signals are acquired at regular intervals by pa5 and pa6. Once the threshold is triggered, the data is immediately moved to a memory array. The discrete-time signal FFT is implemented by DSP library functions, and logic functions are written to extract the spectrum information.

What sensor is used when the laptop is opened at a certain angle and the screen lights up?
Hello, seniors! We are developing a mobile PAD recently, similar to a notebook, and now we have some problems: The screen will light up when it is opened to a certain angle, the angle is 30°, the accu
