P1.0—P1.2分别为南北方向的红，黄，绿灯； P1.3——P1.5为东西方向的红，黄，绿灯；共阴极数码管的a,b,c,d,e,f,g,dp分别接P0.0-P0.7；数码管V0－V2分别接P2.0——P2.2（V0为百位，V1为10位，V2为个位）；南北为主干道，能行时间180秒，黄灯亮3秒，东西为乡村道，通行时间为60秒，黄灯亮3秒；采用T0为中断源，扫描显示数码管，T1为定时器，每次定时0.5秒，两次计数1秒。
-P1.0-P1.2 north-south direction, respectively red, yellow, green P1.3- P1.5 for the east-west direction of the red, yellow, green common cathode LED of a, b, c, d, e , f, g, dp, respectively, then P0.0-P0.7 digital V0-V2 were then P2.0- P2.2 (V0 to one hundred, V1 is 10-bit, V2 is a bit) north and the south main road, can do time 180 seconds, the yellow light for 3 seconds, something for the rural road, access time of 60 seconds, yellow light for 3 seconds use T0 interrupt source, the scans showed that the digital control, T1 for the timer, each timer 0.5 seconds, two counts of 1 second.
