（1． 动态扫描方法

动态接口采用各数码管循环轮流显示的方法，当循环显示频率较高时，利用人眼的暂留特性，看不出闪烁显示现象，这种显示需要一个接口完成字形码的输出（字形选择），另一接口完成各数码管的轮流点亮（数位选择）。

（2． 在进行数码显示的时候，要对显示单元开辟8个显示缓冲区，每个显示缓冲区装有显示的不同数据即可。

（3． 对于显示的字形码数据我们采用查表方法来完成。

-(1. Dynamic Dynamic interface scanning method used in rotation cycle of the digital tube display method, when the cycle showed a higher frequency, the use of the human eye characteristics of the temporary stay, do not show the phenomenon of scintillation, which indicate a need for the completion of an interface font code output (font selection), and the other interfaces to complete the rotation of the digital tube light (digital choice). (2. In a time when digital display, it is necessary to open up on the display unit 8 display buffer, each installed display buffer There are different data can be displayed. (3. The data show that the shape we have adopted a code to complete the look-up table method.
