ZLG7290B 是广州周立功单片机发展有限公司自行设计的数码管显示驱动及键盘扫描
管理芯片。能够直接驱动8 位共阴式数码管(或64 只独立的LED),同时还可以扫描管理
多达64 只按键。其中有8 只按键还可以作为功能键使用,就像电脑键盘上的Ctrl、Shift、
Alt 键一样。另外ZLG7290B 内部还设置有连击计数器,能够使某键按下后不松手而连续有
效。采用I2C 总线方式,与微控制器的接口仅需两根信号线。该芯片为工业级芯片,抗干扰
能力强,在工业测控中已有大量应用。-Canton weeks ZLG7290B is Ligong Singlechip Development Co., Ltd. to design the digital tube display driver and the keyboard scan management chip. Can directly drive a total of 8 vaginal digital tube (or 64 independent LED), at the same time management can also scan up to 64 keys. Which has 8 buttons can also be used as function keys, like the computer keyboard on the Ctrl, Shift, Alt keys like. Another internal ZLG7290B batter has also set up counters, can press a button and a row after不松手effective. Using I2C bus mode microcontroller interface with only two signal lines. The chip-on-chip for industry, anti-interference ability, in the industrial measurement and control has been a large number of applications.

/* 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。
