HC164用来驱动数码管以及LED指示灯，动态扫描数码管的是利用视觉暂留的特性进行显
示景物引起人的视觉印象，在景物消失后还能在视网膜上保持0。1秒的时间叫做视觉暂
留。可以将数据刷新速率可以为10Hz(0.1s)，同时我们需要对四位数据进行扫描，因此
数据刷新速率最低应该为10Hz×4。最高可以为50MHz(HC164可以工作在50－175MHz)。
根据实际情况我们可以定为 762.939453125 = 50MHz因此接口处led,seg_value,dot数据的变化速率最大不能超过为50MHz/2**14
-HC164 digital tube and used to drive LED indicator light, dynamic scanning digital tube is left temporarily use visual display of the characteristics of landscape caused by human visual impression in the landscape after the disappearance of the retina can maintain 0.1 seconds of time is called visual temporary stay. Data can be refresh rate for 10Hz (0.1s), at the same time we need to scan the four data, so data should be the minimum refresh rate of 10Hz × 4. The highest for the 50MHz (HC164 can work in the 50-175MHz). According to the actual situation as we can, therefore 762.939453125 = 50MHz interface led, seg_value, dot data changes can not exceed the maximum rate for the 50MHz/2** 14
