traffic light

This hardware design is used in the design of a traffic light. The main control chip is an STM32F103 series chip. During use, I encountered a problem that the decimal point of the digital tube could not be controlled to go out. This problem has not been solved. Friends who are interested in uploading the program engineering source code can study it and share it together. In the program, you can mainly look at tm1637.c and tm1637.h in MyCodeTM1637. There are other functions in the main program that may be confusing. The main function used in main is RGY_Control(Display_Time,LED1_1_Status,LED1_2_Status);//Display_Time=the time displayed by the digital tube, LED1_1_Status=the left indicator light displays the status, LED1_2_Status=the right two indicator lights display the status (1=red dot On; 2=yellow on; 3=green on; all other values ​​are off) RGY_Control_2(Display_Time,LED2_1_Status,LED2_2_Status); The function is the same as the above function. The use of two signal lights in the design is equivalent to copying it.
