Description: (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.
