#The 7th Lichuang Electric Competition#GT Amperemeter220825

Note: * is a required field,
please fill it in during the registration stage↓
 
* 1. Project Function Introduction
This is a current detection meter for a USB interface that detects current and displays voltage, current, and power in real time through oled. The input of this meter is within 6v and the input is 5v.
This project is made with the reference circuit diagram, pcb, and code provided by the training camp.
 
*2. Project Properties
This project is made with the reference circuit diagram, pcb, and code provided by the training camp.
It is not an original project, and I look forward to having my own original project.
 
* 3. Open Source Agreement
is completely open source.
 
Note: Altruism is self-interest, please read the following carefully.
Embrace open source and give the project unlimited value. 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 form during the competition stage↓
 
*4. The hardware part
uses Jiali Chuang EDA Professional Edition.
N32G430C8L7 is used as the main control chip. Around this chip, two sets of disk pairs are set for RESET and BOOT using the internal crystal oscillator of the chip. It consists of voltage regulator and step-down circuit, sampling circuit, filter circuit, etc.
By converting from the schematic diagram to the PCB version, wiring is performed in it. For beginners, it is mainly imitation, without much creativity, just illogical to deal with it yourself. And through students to help guide. It is not very beautiful at present. I hope to continue to work hard.
 
Note: It is recommended to use Jiali Chuang EDA. If you choose other EDA tools, please upload the schematic diagram in PDF format, PCB drawing in PDF format, and 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 the code provided by the training camp, without expansion.
 
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. BOM list
 
Note: BOM list involved in the project. Please upload a screenshot of the BOM in this location. 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. For the competition LOGO verification,
please upload a project picture containing the competition logo, which 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 and upload it
to https://www.bilibili.com/video/BV1nt4y1j7Br/?vd_source=f4092f7dfacf7afbc5f9b282befcd384
Video requirements: Please shoot horizontally, with a resolution of not 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.
