单片机实时时钟软件，用数码管显示时间，按键调节时间、闹钟
  1. /*
  2. The function of this program is to set the time and judge the time is true or not
  3. the value "location" is marked the location what you are setting "1" represent setting day,"2" represent setting month,"3" represent setting year
  4. the struct "Time" is used to save the time
  5. when value "location" less than or equal 3,it means that you're setting time now,the digment will only show the time you're setting
  6. when value "location" more than 3,it means that you have done the setting of time,the digment will show the whole time
  7. push "left" or "right" button to move the number
  8. push "up" or "down" button to add or minus the number
  9. ###this time set program is just a primer version,it can't calculation the time such as you can set 99days a month###
  10. ###this time program is just a primer+ verson,it not can judge the time is true or not,but it still only can set the data not the time like 2014-03-08,not 22:37:40 ###
  11. this time program is a primer 1.3 verson,it can judge the time is true or not,and it not only can set the data ,it can set the time,too 2014.3.9
  12. this program is a realclock program,it can show the time and set the time with the up-down-left-right keys
  13. this program is a realclock with alarm fucntion ,it can brazzer for 1 minute 2014-03-17
