⚡Program Function Description
<span><span>The functions and principles of this program are as follows:</span></span>
1. Basic functions of the system
Clock display: hours, minutes (24-hour format)
Calendar display: year, month, day
Stopwatch function: accurate to 0.01 seconds, supports start/pause/reset
2. Mode switching function
Our control input has 5 pins, with the analysis of functions as follows:
i_Function_Controller=0; Display year, month, day
i_sel: Select the digit to be adjusted.
i_set: Counter, adjust the digit at the selected position.
During adjustment, first select i_sel, press the button once, the position to be adjusted will move once, then move to the desired position, release i_sel, and then press i_set to adjust the displayed number.
i_run: Not used
i_Function_Controller=1; Display time, hours, minutes, seconds
i_sel:
i_set:
i_run:
During normal operation, the above three settings input 0, 0, 1 respectively
When time adjustment is needed, set i_run=0, then set i_sel to select the corresponding digit to be adjusted, and set i_set to set the specific value, where if i_set is set for seconds, seconds will be cleared directly.
Note that because the time part counts to 24 hours, the year, month, and day are only incremented then, so for year, month, and day, i_run is not used; it is driven by the date module.
i_Function_Controller=3; Control of the stopwatch
i_sel: Clear
i_set: Pause
i_run: Start stopwatch timing
