数码秒表设计:开发板上4键从左至右为S1-S4，上电后，开始时显示 0.0 ；
利用S1按键后启动计时；S2按键后停止计时；S3按键后计时归零；最大计时
为9.9秒。计时误差小于0.2秒，显示稳定。
晶振频率：11.0592MHz -Digital stopwatch design: 4 key development board left to right S1-S4, after power is displayed at the beginning of 0.0
Start timing after use S1 button after S2 button to stop counting after S3 key time to zero the maximum timing
9.9 seconds. Timing error is less than 0.2 seconds, the display is stable.
Crystal frequency: 11.0592MHz
