摘要
随着电子技术的发展,频率测量已成为电子测量领域非常重要的测量之一。本文提出了一种基于STM32单片机频率测量的方案。与传统单片机相比,STM32的主频和定时器的频率可以通过PLL倍频到高达72MHz,能够实现高精度的测量。
With the development of electronic technology,frequency measurement has become one of very important electronic measurement in the field of measurement. This paper proposes a solution based on frequency measurement of STM32 microcontrol er. Compared with the traditional single chip microcomputer,the frequency of the dominant frequency and timer of STM32 through PLL frequency doubling to 72 MHZ,can achieve high precision measurement.
