SimpleOscillograph_For_STM32

已废弃
这是大学时候做的。又做了个更高效的版本,见:https://github.com/shuai132/ScopeMCU

功能

使用STM32作为核心器件,实现三通道示波器,在上位机处理和显示。支持多种触发方式,支持实时采集,最大三通道采样。可以对信号进行加窗处理,并具有FFT频谱分析等功能。

为了程序的可移植性和简单性,使用单独的外部中断边沿触发、使用ADC+DMA自动循环采集数据以及单独的定时器中断触发采集,而没有使用STM32 ADC的外部触发等特性。

说明

  1. 本程序使用STM32的USB开发了虚拟串口,更节约了硬件成本,本身就可以与上位机通信了。当然也可以配置宏并重新编译使用串口与上位机交互(具体见源代码MYDEF.H)。
  2. 需要配合基于LabVIEW开发的上位机程序使用。
