/* 程序详细功能介绍:
* 用AT89S51单片机产生“嘀、嘀、…”报警声从P3.2端口输出,产生频率为1KHz,
* 1KHZ方波从P3.2输出0.2秒,接着0.2秒从P3.2输出电平信号,如此循环下去,就形成我们所需的报警声了。
*
* 程序设计方法
*(1.生活中我们常常到各种各样的报警声,例如“嘀、嘀、…”就是常见的一种声音报警声,
* 但对于这种报警声,嘀0.2秒钟,然后断0.2秒钟,如此循环下去,假设嘀声的频率为1KHz,
* 由于要产生上面的信号,我们把上面的信号分成两部分,一部分为1KHZ方波,
* 占用时间为0.2秒;另一部分为电平,也是占用0.2秒;因此,我们利用单片机的定时/计数器T0作为定时,
* 可以定时0.2秒;同时,也要用单片机产生1KHZ的方波,对于1KHZ的方波信号周期为1ms,
* 高电平占用0.5ms,低电平占用0.5ms,因此也采用定时器T0来完成0.5ms的定时;
* 最后,可以选定定时/计数器T0的定时时间为0.5ms,而要定时0.2秒则是0.5ms的400倍,
* 也就是说以0.5ms定时400次就达到0.2秒的定时时间了。

At can be given its arguments in a file. You can comment
out lines by preceding them with either # or -
characters. This is an easy way to temporarily disable
some commands.
The CONTINUE-command is most useful at the end of the
file. When this command is read, the file is started
again from the beginning. You can use it situations where
the machine is not shut down for the night and you want
to run some commands every day.- At can be given its arguments in a file. You can comment
