摘要：本系统采用STM32为主控核心，做数据的处理，彩屏的显示，波形的判别等工作。用FPGA进行测频、测相以及测脉宽，可变的占空比的方波 更多：https://www.bmcx.com/ ，用其测得的数据返回主控芯片进行处理。正弦波和方波的辨别用比较器ＬＭ３９３搭载并配合FPGA来实现。系统自动分辨出波形后用TFT来显示其波形，用AD637来测量正弦波的峰峰值。并比较原波形及经过ＲＣ移相后的波形，测量出其相位差，并在彩屏上给予显示。实现了方波、正弦波两种简易信号的测量。 关键词：STM32 FPGA ＬＭ３９３ AD637 产品信号测量

Abstract: the system USES as the controller STM32 core, do data processing, color display, waveform of discrimination, etc. Using the FPGA for measuring frequency, phase and the measuring pulse width 更多：https://www.bmcx.com/ , variable occupies emptiescompared to square wave, use of the measured data of the main control chip return for processing.Sine wave and identify the square with the comparator LM393 launch and cooperate with FPGA to achieve. The system automatically distinguish waveform with TFT to display its after wave, with AD637 to measure the sine wave fengfeng value. And compare the original waveform and after the waveform phase shifting RC, measured the phase difference, and for display in color.Realize the square wave, sine wave two simple signal measurement. keywords: STM32 FPGA LM393 AD637 signal measurement
