设计了低成本、低功耗的多功能示波器，采用了ST 公司的STM32F4系列的单片机作为主控芯片，用片内AD进行采样，省去了AD转换芯片和FPGA ，以此降低成本，同时运用STM32F4片内的FPU（浮点运算单元）还能对波形进行数学运算。多功能便携示波器全部使用触摸屏操作的方案使应用更加方便、快捷、形象。

A low cost ,low power consumption multifunction oscilloscope was designed by using ST’s STM32F4 Series MCU as the main control chip .The build-in AD was used instead of external AD conversion chip and FPGA to reduce the cost .At the same time ,STM32F4 FPU could also realize mathematical transformations on the waveform .The touch screen operation scheme was more conven-ient ,quick and intuitive .
