【摘要】:本系統(tǒng)主要是基于單片機(jī)STC89C52為核心的控制單元實(shí)現(xiàn);單片機(jī)P3口控制各個(gè)路口紅、綠、黃燈,P20口-P23口作為數(shù)碼管位選開關(guān)實(shí)現(xiàn)動態(tài)掃描,P0口用于傳輸數(shù)據(jù)給數(shù)碼管顯示數(shù)字。能實(shí)現(xiàn)各個(gè)路口信號燈自動有序的切換并伴隨時(shí)間顯示。
[Abstract]:The system is mainly realized by the control unit based on STC89C52, and the P3 port controls the red, green and yellow lights in every intersection. The P20 port-P23 port is used as the digital tube position selection switch to realize the dynamic scanning P0 port for transmitting data to the digital tube to display the digital data. Can realize each intersection signal light automatic orderly switch and accompany the time display.
