利用动态扫描和定时器1在数码管上显示出从765432开始以1/10秒的速度往下递减直至765398并保持显示此数，与此同时利用定时器0以500MS速度进行流水灯从上至下移动，当数码管上数减到停止时，实验板上流水灯也停止然后全部开始闪烁，3秒后（用T0定时）流水灯全部关闭、数码管上显示出“HELLO”。到此保持住。-The use of dynamic scanning and Timer 1 in the digital control on the show to start from 765,432 to 1/10 seconds reduced the speed down and keep up to 765,398 the number of shows at the same time the use of Timer 0 to 500MS speed of light from the water to Under the move, when the digital control reduced the number of stops on the experimental water board has to stop and then all the lights started to flicker, 3 seconds (from time to time with T0) closed water lights, digital tubes display a " HELLO" . Maintain this.
