* 硬件结构： PA0-5对应６个ＬＥＤ数显管的位 ，PC0-7对应各ＬＥＤ数显管的段 ，PB4-7为键盘。

* 软件描述： 上电后，时钟从00.00.00（时/分/秒）自动走时，在走时状态时 ， 按PB4（设定

* 键）超过3秒可循环选择调整时间/工作参数 ，接着按PB5以确定选择的操作 ，进入调整操作后 ，

* 按PB5选择欲调整参数，按PB6（增加键）完成调整参数操作 。按PB7，进入时控运行，PB1亮，

* 再按PB7停止时控运行，回显走时。在定时到时，PB0点亮。- * Hardware architecture: PA0-5 corresponds 6 LED numbers to reveal the tube the position, PC0-7 corresponds each LED number to reveal the tube the section, PB4-7 is a keyboard.

* Software descr iption: After on electricity, clock from 00.00.00 (when/a minute/second) is in luck automatically, when is in luck the condition, according to PB4 (hypothesis

* The key) surpasses for 3 seconds to be possible to circulate the choice time/operational parameter, then presses PB5 by to determine the choice the operation, after enters the adjustment operation

* Wants according to the PB5 choice to adjust the parameter, (increases key) according to PB6 to complete the adjustment parameter operation.According to PB7, enters when controls the movement, PB1 is bright

* Presses when again the PB7 stop controls the movement, returns reveals is in luck.In fixed time at the appointed time, PB0 lightens.
