- 用AT89S51单片机产生“嘀、嘀、…”报警声从P1.0端口输出，产生频率为1KHz，根据上面图可知：1KHZ方波从P1.0输出0.2秒，接着0.2秒从P1.0输出电平信号，如此循环下去，就形成我们所需的报警声了。-Use AT89S51 microcontroller have a "tick, tick, ..." alarm sound from the P1.0 port output, resulting in a frequency of 1KHz, according to the
pinlv
- 利用AT89S51单片机的T0、T1的定时计数器功能，来完成对输入的信号进行频率计数，计数的频率结果通过8位动态数码管显示出来。要求能够对0－250KHZ的信号频率进行准确计数，计数误差不超过±1HZ。-AT89S51 microcontroller using T0, T1 timing counter functionality to complete the input signal frequency count, counting the frequency of the result
