本程序集成中断、定时器、LED灯、数码管显示，可完成每隔100ms数码管显示的数减小1，同时以500ms的速度进行流水灯，当数码管上的数停止，实验板上流水灯也停止然后全部开始闪烁，3s后流水灯全部关闭、数码管上显示 出"8520",然后保持住-This program integrated interrupt, timer, LED lights, digital display, to be completed by every 100ms digital display reduces the number 1, while the speed of 500ms water to light, when the number of stops on the digital control experiment on-board water Then all the lights have stopped flashing, 3s after the water all the lights turned off, digital tube display " 8520" , and then hold
