单片机系统中的汉字显示 摘要: 需要显示的汉字较多时,单片机系统中的汉字编码非常繁琐。本文介绍一种直接利用PC机的汉字内码作为单片机系统的汉字编码,以简化系统的设计。-SCM system of Chinese character display Abstract : The need to show the Chinese characters more, the SCM system of Chinese character coding very cumbersome. This paper presents a direct use of the PC as the Chinese character coding SCM Chinese character coding system to simplify system design.

/* 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。
