There is something wrong with the program, please solve it [Copy link]

The course has been designed for a week, and I have encountered many problems with the program and schematic diagram. The following three have not been solved yet. Please give me some advice and save the children! Please solve these three problems: Countdown does not work, Emergency mode does not respond, Modify time does not respond

For this kind of problem, we should find a problem step by step, annotate each function one by one, if the countdown is abnormal, we should find out whether the timer is working properly, whether the display function is normal, etc. If the mode cannot be switched, is it a button judgment problem, or a conflict in logic? In most cases, we can locate the approximate problem by figuring out a little bit, and then think of a solution.

It's not easy to help. It takes half a day to read the program.
