This design includes Proteus simulation + program + design report + explanatory video.
1. Development Environment
Simulation diagram: Proteus 8.17 (lower versions available)
Compiler: Keil 4/Keil 5
Programming Language: C
Design Number: P22
2. Main Functions:
1. Use a 7-segment display as the display device to design the clock function;
2. Allows separate adjustment of hours, minutes, and seconds, resets to 00:00:00, and can be set to 24 or 12-hour format;
3. Extended functions:
Includes an alarm function, which can be set via buttons, with a default alarm time of 00:01;
12/24 hour format has corresponding indicator lights, with AM/PM indicators.
Main hardware: 51 microcontroller, DS1302, 7-segment display, independent buttons, LED
(Currently fully compatible with the Puzhong 51 experimental board 234; other Puzhong development board models require wiring)
Note that the 51 microcontroller chip in the simulation is compatible; AT89C51 and AT89C52 are specific models of the 51 microcontroller, with the same core. In the same schematic, whether STC or AT, the pin functions are the same, the programs are compatible, and the chips can be replaced with STC89C52/STC89C51/AT89C52/AT89C51 and other 51 microcontroller chips.

4. Simulation Design
Open the simulation project, double-click the microcontroller in Proteus, select the hex file path, and then start the simulation. After starting the simulation, the 7-segment display shows time 00:00:00. The time increments by seconds.
While displaying the time, press the set button to enter the setting mode, the clock blinks indicating that the clock is currently being set, then press the set button to enter the minute setting mode, the minutes blink, and then press the set button to enter the second setting mode, the seconds blink. After setting the seconds, press set to exit the setting mode, and the 7-segment display shows normally.
When not in the setting state, the + button serves as a toggle button to switch between 12/24 hour formats. In 12-hour format, there is a light indicator for AM or PM, thus achieving AM/PM indication.
Press the function switch button to display the alarm time. In the alarm time display, press the set button to enter the alarm setting mode, the clock blinks indicating that the alarm clock is currently being set, then press the set button to enter the alarm minute setting mode, the alarm minutes blink, and then press the set button to enter the alarm second setting mode, the alarm seconds blink. After setting the seconds, press set to exit the setting mode, and the 7-segment display shows the alarm time normally.
When the alarm time is reached, the buzzer rings, and the buzzer sounds for 6 seconds.
5. Program Code
Use Keil 4 or Keil 5 to compile, the code is commented, and can be understood in conjunction with the video.
