普通PC键盘作为输入设备与单片机串行连接，通过单片机解码PS2键盘，七段数码管显示按下的键值，是把键盘作为输入扩展的不错的例程，源码采用KEIL C编写。(keyboard input)

The LED clock consists of 60 LEDs which are placed circular around a common analog clock. The LEDs are used to display the seconds. Essential part of this circuit is the LED driver MAX7219 from Maxim. A datasheet is available on Maxim s homepage. The clock is controlled by the microcontroller AT89C2051 from Atmel. This microcontroller is clocked at a frequency of 12 MHz from which results a time base of 1 microsecond. Via software dividers one clock impulse per second is generated which is used for updating the LED display.

开发平台为Keil Cx51,能实现多级菜单，相信会对大家的C51编程又一定的应用价值.(development platform for Keil inverter can achieve multi-level menu, We believe that the C51 will be in a certain programming the application.)
