基于51单片机的LED数码管动态显示，LED数码管动态显示就是一位一位地轮流点亮各位数码管，对于每一位LED数码管来说，每隔一段时间点亮一次，利用人眼的“视觉暂留"效应，采用循环扫描的方式，分时轮流选通各数码管的公共端，使数码管轮流导通显示。-Based on 51 single-chip LED digital tube dynamic display, LED digital tube dynamic display is a bit lit Members take turns digital tube for every LED digital tube lights up every once in a while using the human eye"persistence of vision" effect, using cyclic scan, time turns the public end gated digital tube digital tube turns conduction display.
