用AT89S51的定时/计数器T0产生2秒钟的定时,每当2秒定时到来时,更换指示灯闪烁,每个指示闪烁的频率为0.2秒,也就是说,开始L1指示灯以0.2秒的速率闪烁,当2秒定时到来之后,L2开始以0.2秒的速率闪烁,如此循环下去。0.2秒的闪烁速率也由定时/计数器T0来完成。 -AT89S51 with the timer/counter T0 have 2 seconds of the time, whenever the arrival of two seconds from time to time, the replacement indicator light flashes, each indicative of the frequency of blinking 0.2 seconds, that is, the beginning of L1 indicator of the rate to 0.2 seconds flashes, when, after the arrival of two seconds from time to time, L2 began to flicker rate of 0.2 seconds, and so the cycle continues.
