采用两个定时器合用，T0设置为定时方式，T1设置为计数方式。T0定时时间为50ms，计满产生的输出信号由P1.7口发光二极管显示。同时还将该信号输入到计数器T1（P3.5脚）作为T1的计数输入脉冲，当输入信号产生由1到0的跳变时触发计数器工作,使计数器的值增1。计数器T1的初始值设置为100，计满时所用的时间为50ms×2×100，即10s。并由P1.0端口发光二极管来显示，所以P1.0端口的灯每10s点亮或熄灭一次-Combined use of two timers, T0 is set to regular mode, T1 is set to count the way. T0 regular time 50ms, the expiration of the output signal produced by light-emitting diode display P1.7 mouth. At the same time will also be the signal input to counter T1 (P3.5 feet) as T1 count input pulse, when the input signal generated by the 1-0 hopping trigger counter, so that the value of counter by 1. The initial value of T1 counter is set to 100, used by the expiration time for 50ms × 2 × 100, or 10s. P1.0 port by the light-emitting diode displays, so P1.0 port lights lit every 10s or extinguish a
