<> Blue Bridge Cup 8 Provincial Games _ Electronic clock
Modified version
Basic knowledge learning comes from little bee teacher yyds
The following code functions are not fully implemented If there is any mistake, I hope the boss will correct it
Summary and analysis ：
Personally, the difficulty of the eighth session is obviously much harder than that of the seventh session , Of course, it may also be that I haven't mastered the relevant programming in this aspect From my personal problems in programming .
First of all, when you start programming, you must read the topic clearly and understand it Let your brain have a basic framework , Then it is divided into modular programming Make corresponding logical combination , Remember not to come back to the mode after you have written it all
Write some functions and debug them In this way, even if there is an error, it can quickly locate the error and solve it , Secondly, when practicing by yourself Be patient with the debugging of the program , This is also a crucial factor in success
, Solve it myself Bug It took a long time, even a small mistake Sometimes they have been debugged many times Fortunately, I didn't give up and finally solved it successfully .
Some problems were encountered at the beginning of the eighth topic practice , Then I want to find the code written by other big guys on the Internet , From the heart, what they write is really good
But maybe I'm too shallow to understand , Then we can only rely on ourselves to realize it slowly bit by bit It took nearly as long as the game 2 In the final analysis, I didn't practice enough Um It can only be said that we should continue to work hard .
The function of the following program is tested on my development board There is no problem with the display of various modes At that time, I didn't know why to modify the clock and set the alarm clock There is something wrong with the number displayed
then Led The function of the operation has not been written yet , It will continue to be improved in the future .
What a long long road! come on.
