1：P1口接8个LED，单脉冲电路的负脉冲端接到单片机的P3.2引脚上。编写程序，使定时器0的中断方式产生100ms的延时，实现8个LED的亮点流动。在流动的过程中，如果按下单脉冲键，8个LED的发光状态将改变为同时闪烁，闪烁8次恢复亮点流动（闪烁时间间隔由延时程序完成）。

-1: P1 mouth 8 LED the negative pulse end of the single-pulse circuit connected to the MCU P3.2 pin. Writing programs, a 100ms delay timer 0 interrupt, 8 LED highlights of liquidity. In the flow of the process, if you press a single pulse button, 8 LED light-emitting state will change to flash simultaneously flashes 8 times to restore the flow of the highlights (flashing interval delay program completion).
