1. Design Description

This design carefully builds a comprehensive embedded system with STM32MP157A high-performance single-chip microcomputer as the core control unit. The system cleverly integrates multiple peripheral modules such as buzzer, digital tube display, dot matrix screen, temperature and humidity sensor, LED indicator light and button to form a hybrid intelligent device with rich functions and convenient operation. Through serial communication, users can flexibly switch the working mode of the system and easily realize basic functions such as alarm clock, music box playback and temperature and humidity monitoring and control.

Core Hardware

  • Main control unit：The STM32MP157A microcontroller provides a solid hardware foundation for the system with its powerful processing capability and rich peripheral interfaces.

software platform

  • development tools：Using the intuitive and easy-to-use integrated development environment STM32CUBEIDE, the efficiency of software programming and debugging is greatly improved, ensuring the stability and reliability of the system software.

System Function Highlights

  1. Flexible mode switching: Through serial port communication, users can easily switch between the three modes of alarm clock, music box playback and temperature and humidity monitoring to meet the usage needs in different scenarios.

  2. Dynamic information display：The dot matrix screen serves as the information display window of the system. It can display the corresponding Chinese characters according to the current working mode (such as "钟" represents the alarm clock mode, "音" represents the music box mode, and "传" can be regarded as a simplified symbol for temperature and humidity monitoring), providing users with intuitive operation feedback.

  3. Key interaction experience：The design fully considers the user's interactive experience. The corresponding functional operations can be performed in each mode by pressing buttons, such as adjusting the speed and volume of the music box, switching songs, pause/play control, as well as adjusting the alarm time, setting multiple alarms, turning off the alarm, etc.

  4. Intelligent temperature and humidity control：The system has a built-in temperature and humidity sensor that can monitor environmental conditions in real time and receive user instructions through the serial port to adjust the upper and lower thresholds of temperature and humidity. Once the environmental parameters exceed the set range, the LED indicator will light up as a boundary prompt to help users take timely measures.

2. Basic configuration information

The music box has been made before so the configuration does not change:STM32 Music Box

        

3. STM32CUBEIDE configuration

1. Timer--100ms

2. PWM configuration (buzzer -- PB6)

3. Serial port configuration

Note the pins

4. IIC configuration (temperature and humidity, digital tube, dot matrix screen)

5. GPIO configuration (LED and buttons)

6. NVIC

4. Programming

(1) Music box code

The music box has been written before, so I will not repeat the previous operations here. We will add the serial port and mode conversion.

VII. Conclusion

This design is a highly integrated multifunctional system based on the STM32MP157A microcontroller. It realizes rich interactions and functions by integrating multiple modules such as buzzer, digital tube, dot matrix screen, temperature and humidity sensor, LED light, button, etc. The system uses STM32CUBEIDE as a development platform, giving full play to the high performance and flexibility of the STM32MP157A microcontroller, and showing its wide application potential in embedded system design.

Design summary:

  1. Modular design：This design adopts a modular design approach, integrating different functional modules (such as alarm clock, music box, temperature and humidity monitoring) after independent design. It not only improves the maintainability and scalability of the system, but also makes the functional implementation of each module clearer.

  2. Flexible mode switching: Flexible switching between different modes (alarm clock, music box, temperature and humidity monitoring) is achieved through serial port communication, allowing users to easily select the required functions according to their needs, improving the user-friendliness and practicality of the system.

  3. Diverse display and interaction：The dot matrix screen displays different Chinese characters (such as "钟", "音", "传") in different modes, which intuitively shows the current working mode and enhances the user experience. At the same time, the combination of buttons and serial port control allows users to operate the system in a variety of ways, such as adjusting the music playback speed, volume, switching songs, adjusting the alarm time, setting multiple alarms, etc., which greatly enriches the system's interactive methods.

  4. Temperature and humidity monitoring and adjustment：The system integrates temperature and humidity sensors, which can monitor the ambient temperature and humidity in real time, and adjust the upper and lower limits of temperature and humidity through the serial port. When the temperature and humidity exceed the set range, the boundary prompt is given through the LED light, realizing intelligent monitoring and adjustment of the environment.

  5. Efficient development platform：Using STM32CUBEIDE as the development platform, taking advantage of its powerful code editing, compiling, debugging functions, as well as rich library functions and sample projects, it greatly improves development efficiency and reduces development difficulty.

  6. Demonstration of comprehensive application capabilities：This design not only demonstrates the powerful functions of the STM32MP157A microcontroller in embedded system design, but also reflects the designer's comprehensive application capabilities in hardware selection, circuit design, software programming, system debugging, etc.

In summary, this design is an embedded system that integrates versatility, flexibility, and user-friendliness, fully demonstrating the broad application prospects and potential of the STM32MP157A microcontroller in complex system design. Through the implementation of this design, not only has the understanding of embedded system design been deepened, but also the ability to solve practical problems has been improved.
