摘　　要：本文以STM32 NUCLEO开发板为核心,利用芯片内部的模数转换器将心率传感器测得的模拟心率信号转换成数字信号,并在OLED液晶屏上显示心率数据。为便于观察,主控板内部还将数据绘制成波形图显示于OLED屏。另外,系统应用串口通讯模块连接主控板和CPU,以达到对心率信号深入分析和处理的目的。STM32 NUCLEO board was taken as the development core in this project,and then the heart rate signal measured by the heart rate sensor was converted into digital signal by using the analog-to-digital converter inside the chip.In order to observe the heart rate more intuitively,the collected data was displayed and plotted into waveforms on OLED LCD screen.In addition,the system uses serial communication module to connect the main control board and CPU,in order to achieve in-depth analysis and processing of heart rate signals.
