温馨提示
开发环境: 1、win10 +MDK keil5.24 2、ST-LINK下载器(不一定需要这个,J-LINK和串口下载都是可以的) 我是用的是STM32F103C8T6最小系统板,价格比较便宜并且功能足够强大。 元器件有: ==>pulse sensor心率传感器 ==>IIC OLED显示屏 ==>按键2个 ==>LED1个 ==>蜂鸣器1个 电路设计:在硬件结构方面还是比较简单的,连线比较简单。 软件实现:OLED方面我采用的是IIC操作的OLED,因为IIC操作简单,只需要两根线(我直接使用的PA7和PA8)。使用了软件IIC,直接移植的正点原子的官方例程的IIC,OLED显示也是移植的正点原子的程序,只是做了改进,可以显示汉字(正点原子的官方例程中OLED程序不能显示汉字,我对代码进行升级,可以显示汉字),还增加了自动在数字前面补0的功能。 pulse sensor心率传感器采用ADC进行数据采集,使用到了ADC0(PA0)。通过配置ADC引脚完成ADC的采集,通过实验,可以正常的采集到数据。当人的手指放上之后用示波器可以看到心跳的电压变化。
