#The 8th Lichuang Electronic Competition#Desktop Clock

Note: * is a required field,
please fill it in during the registration stage↓
 
* 1.
Please enter the content of the project function introduction...
1. Renesas R7FA2E1A72DFL is used as the main control chip of the electronic clock.
2. A four-digit 0.56-inch common cathode digital tube is used to display the time.
3. The ambient temperature is collected through the DHT11 temperature and humidity sensor.
4. Four buttons are used for clock setting buttons:
       long press SW1 to enter the calibration time mode, and the time can be calibrated when the digital tube numbers flash. Long press SW2 to subtract, long press SW3 to add, and SW4 is invalid;
       long press SW4 to switch to temperature and humidity mode (the buzzer sounds once each time it is switched). The first time displays the temperature, the second time displays the humidity, and the third time returns to the time display;
       if the mode is not entered, long press SW2/3 is invalid.
5. Lead out a reset button, serial port circuit, and SWD download circuit to facilitate download and debugging (the project uses SWD download)
6. The Renesas chip integrates a touch pin, and a touch pin is led out to be used as a touch button (the program does not implement this function)
7. Use a passive buzzer as a reminder of time reaching (not added in the program, you can add it if you need it, buzzer.c contains MIDI music functions and functions for buzzer ringing once)
8. Use AO3401A+1N5819 diodes to form a power switching circuit
9. Use TP4056 to charge the lithium battery (red light + yellow light charging, red light + green light charging completed)
10. Use Flash to remember time, and power off to record the last time
11. Power on/reset will have a few tens of seconds of MIDI music playing at one end
Note: The theme is not limited, it can be a solution to a problem in life/work, a solution designed for a certain group of people/scene, a graduation project/course design/DIY project/purely cool project, etc. Mainly talk about what problems you solved by what means. *2. Please enter
 
the project attributes ... 1. This project is a replica of the desktop clock of the LiChuang summer training camp. The circuit design was done according to the training camp. 2. The program is basically modeled after the design of Renesas Xiaogong in the training camp, but he used E2 development, and I transplanted the program to it using RASC+keil5, and used the Hezhou small blackboard daplink to burn the program. Some of the program files were modified or added by me. Note: Please indicate whether the project is publicly disclosed for the first time; whether the project is original; whether the project has won awards in other competitions, if so, please describe the details of the award; whether the project has participated in the defense at school. * 3. Please enter the open source agreement... Note: Altruism is self-interest, please read the following content carefully. Embrace open source and give unlimited value to the project. It is recommended that more than 80% of the core functions of the project be open source; if a part of the function is irreplaceable and the project cannot solve the corresponding problem after deleting it, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic load is the core function and the host computer software is an auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function; the project should choose an open source protocol that suits it. If the project references other open source projects, the source should be indicated and the original author's open source protocol should be followed; the original project is recommended to use the GPL3.0 open source protocol; the functions directly referenced from the original circuit or original code of the open source project cannot be used as the core functions of your own project, and the functions directly implemented using the general modules on the market cannot be used as the core functions of your own project. Please fill in the following in the competition stage↓ *4. Please enter the content for the hardware part ... Note: It is recommended to use Jiali Chuang EDA. If you choose other EDA tools, please upload the schematic diagram in PDF format, the PCB drawing in PDF format, and the PCB file in Gerber format in the attachment. Here you can explain in detail the implementation principle and mechanism of your project, precautions, debugging methods, testing methods, etc. It is recommended to introduce your ideas to others in the form of pictures and texts. *5. Please enter the content of the software part... Note: If your project involves software development, please upload the corresponding engineering source code in the attachment. Here you can explain in detail your software flow chart, functional module block diagram, explanation or popular science of related algorithms, source code structure, compilation environment construction and configuration, source code compilation method, program burning method, etc. It is recommended to introduce your ideas to others in the form of pictures and texts. *6. Please enter the content of the BOM list... Note: The BOM list involved in the project. Please upload a screenshot of the BOM in this position. Please upload the list details in PDF format to the attachment. It is recommended to include model, brand, name, package, procurement channel, purpose, etc. The specific content and form should be based on the clear expression of the project composition. *7. Competition LOGO verification contains the project picture of the competition logo, and the logo is printed on the PCB in the form of silk screen. Click zip to download the competition logo! (Competition logo).zip * 8. Demonstrate your project and record it into a video to upload. Video requirements: Please shoot horizontally, with a resolution of no less than 1280×720, in Mp4/Mov format, and a single video size limited to 100M; Video title: Lichuang Electric Competition: {Project Name}-{Video Module Name}; For example, Lichuang Electric Competition: "Autonomous Driving"-Team Introduction.
