#The7thLiChuangElectricityContest#USBBasicVoltageAmperemeter

Overview

* 1. Introduction of project function:
USB voltage and current meter is made based on N32G430 MCU chip of National Technology
* 2. Project attributes:
This project is open and based on the principle diagram of #7th Lichuang Electric Competition#USB Basic Voltage and Current Meter#.
* 3. Open source agreement
GPL3.0
* 4. The hardware part
is based on the official redrawing of the PCB front and back of #7th Lichuang Electric Competition#USB Basic Voltage and
Current Meter:
the line width of the sampling resistor area should be increased, and the power supply part should be as thick as possible to increase the overvoltage and current capabilities.
The GND part has a large area of ground and a large number of vias to ensure strong overcurrent capability of the loop

* 5. The software part
quotes the official code of #7th Lichuang Electric Competition#USB Basic Voltage and Current Meter
* 6. BOM list

* 7. Competition LOGO verification

Are you not interested in capacitive touch?
[i=s]This post was last edited by juring on 2017-3-6 11:38[/i] I have a project that uses capacitive touch recently. Do you have any recommended solutions? The product needs to pass EMC testing and ha
Temperature collection and display based on 52 single chip microcomputer of DS18B20 temperature sensor
I wanted to use this sensor and 52 MCU to realize the function of temperature collection and 1602A display, but I don't know why the temperature remains unchanged. Can someone help me find out what's
Help! Serial port receiving problem of mini2440 development board
I use the FIFO mode of the mini2440 serial port to send a txt file from the SSCOM32 on the computer and receive it on the development board. Why can I only receive up to 255 bytes? Once it exceeds 256
Ask about the dosFsVolFormat function of the file system
I created the ram file system according to the following steps:char *ramDiskDevName = "/ram0" ;CBIO_DEV_ID cbio ; cbio = ramDiskDevCreate((unsigned char *)RAM_DISK_ADDRESS, 128, 1024*3, 1024*3, 0) ;if
Is the FPGA in the image card connected to external SRAM or SDRAM?
Experts: I want to make an image processing card now. I am still discussing the solution. Because I have no experience in FPGA development (I used to work in pre-sales, but now I have changed companie
Share a beginner's lesson on electrician: capacitor discharge
The electrolytic capacitor still has 300V voltage when the circuit board is powered off. Use your bad test lead to connect a 30K resistor in series. When repairing the board, just discharge the large
