#The7thLiChuangElectricityContest#USB Table

Note: * is a required field,
please fill it out during the registration stage↓
 
* 1. Project Function Introduction
Measure the voltage and current flowing through the USB
Note: The topic 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 problem you solved by what means.
 
*2. Project attributes
The project is open to the public for the first time, original, has not won awards in other competitions, and has not participated in the school defense
 
Note: Please indicate whether the project is open to the public for the first time; whether the project is original; whether the project has won awards in other competitions, if so, describe the details of the award; whether the project has participated in the defense at school.
 
* 3. Open Source Agreement
GPL3.0
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 open source protocol of the original author should be followed; the original project is recommended to use the GPL3.0 open source protocol;
the functions implemented by directly referencing 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 by 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. The hardware part
is developed using the MCU of National Technology, supports PD fast charging, and is divided into two versions: 5-20V and 12-26V. Please pay attention to the packaging and withstand voltage value of the capacitor for user convenience.
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. The software part
is developed using keil, and supports downloading via J-link, ST-link, serial port, etc.
 
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 popularization 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
