摘　　要：基于LabVIEW虚拟仪器平台,该文设计了一个电子元器件测量系统。该系统采用STM32单片机作为主控芯片,首先利用NE555定时器组成电阻、电容、电感测量电路,获得待测元件的测量值;然后通过ESP8266模块使得单片机与LabVIEW平台进行通信,将测量值传入LabVIEW上位机;最后由软件判断、存储并显示测试结果。同理,上位机也可给单片机传输数据,利用DAC0832数模芯片和LM358运算放大器组成的函数信号发生电路,完成基本函数信号输出。Based on LabVIEW virtual instrument platform,an electronic component measurement system is designed.This system uses STM32 single-chip computer as the main control chip,uses NE555 timer to form resistance,capacitance and inductance measurement circuit,obtain the measurement value of the component to be measured.Finally,the single-chip computer communicates with LabVIEW platform through ESP8266 module.Similarly,the upper computer can transmit data to the single-chip computer,and use the function signal generation circuit composed of DAC0832 digital-analog chip and LM358 operational amplifier to complete the basic function signal output.
