通过中规模数字电路控制数码管，形成简易的数字钟-In digital circuits Nixie light digital clock

数字钟verilog hdl数字钟数字钟 数字钟简易数字钟(This is a simple digital clock, the language is Verilog HDL, including buffeting and dividing frequency and other functions)

51单片机实现控制8位数码管，但是不能掉电保存。在上电之后可以使用按键控制时间设置，闹钟等功能，还可以使用8001播放音乐(The 51 MCU realizes the control of the 8 bit digital tube, but it can not be saved. You can use key control time settings, alarm clock and other functions, and you can use 8001 music.)
