temperature
- 此设计以单片机STC89C51为核心,由声音传感器采集脉搏信号,经过LM324前置放大电路、滤波电路和比较电路后得到与脉搏相关的脉冲信号,将该脉冲信号作为定时/计数器T1中断信号交由单片机进行脉冲周期的计算,T0做定时器。然后得出每分钟的脉搏搏动次数(即心率),并将结果1602LCD上显示心率。在对人体脉搏检测时,具有检错排错的功能。若出现误操作(如不小心移动时产生的噪声)造成检测到的心跳次数不正确的结果,所以在程序中检测时间到达第5秒时,先对其进行计算,若结果超出正常范围则自动返回重新检测,直

Stm32Systick
- Systick 就是一个定时器而已,只是它放在了 NVIC 中,主要的目的是为了 给操作系统提供一个硬件上的中断(号称滴答中断)。啥叫滴答中断?这里来简单地解释一下。操作系统进行运转的时 候,也会有“心跳”。 -Systick is just a timer, but it in the NVIC, the main purpose is to To the operating system to provide a hardware interrupt (k
