程序工作流程是：

1、产品按下电源开关，给电机及电刷供电，电机开始转

动，单片机得电也开始工作；

2、循环等待24圈，让电机转速基本稳定；

3、一圈计时，然后根据需要显示的总点数计算出每点的

延时；

4、检测同步信号；

5、取显示数据输出到端口上、延时，重复显示完所有的

数据；

6、一直重复第4、5步。-Workflow process are: 1, product press the power switch, power supply to the motor and brush, motor began to rotate, a single-chip power have begun to work　2, circle of waiting for 24 laps, so that the stability of motor speed　3, a circle time, and then show the total points to calculate the delay of each point　4, detection of synchronization signal　5, show the data output from the port, delay, duplication of all the data displayed　6, paragraph 4 has been repeated , step 5.
