（1） Divid 模块：1Hz 分频模块，开发板提供50MHz 的系统时钟，而该设计交通灯
转换以秒为计时单位，对50MHz 分频得到1Hz 脉冲信号。
（2） Divid_200 模块: 200Hz 分频模块,用于产生动态扫描模块的时钟。一个数码管
稳定显示要求的切换频率要大于50Hz，那么4 个数码管则需要50×4＝200Hz 以上
的切换频率才能看到不闪烁并且持续稳定显示的字符，因而扫描频率设定为
200Hz。
（3） Control 模块：A、B 方向红绿灯控制模块，红灯、绿灯为20 秒，黄灯为5 秒。
并实现计时数据转换，即将数据分为十位显示数据，与各位显示数据，用于数码管
显示。
（4） saomiao 扫描模块：轮流选通2 位数码管，实现动态扫描，以显示倒计时数据。-(1) Divid module: 1Hz divider module, the development board provides 50MHz system clock, and the design of traffic lights
Conversion in seconds for the time unit, the 50MHz frequency to be 1Hz pulse signal.
(2) Divid_200 module: 200Hz frequency division module, used to generate the dynamic scanning module clock. A digital tube
Stable display requirements of the switching frequency is greater than 50Hz, then the four digital tubes need 50 × 4 200Hz or more
Of the switching frequency to see the non-flickering and continuous display of the characters, so the scanning frequency is set to
200Hz.
(3) Control module: A, B direction traffic light control module, red, green for 20 seconds, yellow for 5 seconds.
And to achieve timing data conversion, the data is divided into ten display data, and you display data for digital
display.
(4) saomiao scanning module: 2-bit strobe digital control, dynamic scanning to show the countdown data.
