Note: * is a required field,
please fill it in during the registration stage↓
 
* 1. Project function introduction
Please enter the content... USB voltage, current and power meter based on N32G430C8L7, using 24P full-pin male and female sockets, full blood 3.1, 24P line all routed, retaining the lightning protocol communication capability
(impedance is not matched, equal length routing, you need to paste aluminum shielding to avoid RXTX signal interference)
The overall modular design is adopted, and the 3.3V power supply can be freely changed from LDO to DCDC, or the sampling circuit can be replaced, etc. Multiple groups of idle IIC/ADC interfaces are introduced, and other functions such as temperature measurement can be added through flying lines.
 
*2. Project attributes
Original project.
* 3. Open source agreement
GPL3.0
*4. The hardware part
is based on the N32G430C8L7 main control, and the power supply uses SE8633LDO, which supports up to 80V input to ensure safety. The current detection supports INA199/226. The overall structure uses a multi-layer stacking design, retains 24P full pins, supports the measurement of Thunderbolt hard disk boxes, etc. The bias hardware position is reserved and can be changed to support bidirectional functions.
*5. The software part
uses an unofficial solution, the code is slightly modified, and the screen can be turned on by flashing the official solution

#The 7th Lichuang Electric Competition#Current and voltage table

Introduction: The current and voltage meter is made using the National Technology MCU - N32G430C8L7.

1. Project function introduction:
 
This is a current and voltage meter made using the National Technology MCU - N32G430C8L7.
 
2. Project attributes:
 
This project is open to the public for the first time.
 
3. Open source agreement
 
GPL 3.0
 
4. Hardware part:
 
The hardware part is designed using EasyEDA.
 
This project is designed with reference to the chip manual. The necessary pins for the chip to work are configured, such as VDD and VSS (see the data manual for special configurations of some pins). In the burning program part, the NRST and PD0-BOOT0 pins are used for mode selection, PA14 (SWCLK) and PA13 (SWDIO) are used for SW download, that is, keil can be used for direct download, PA10 (USART_RX) and PA9 (USART_TX) are used for serial port download, and hex files are used for download. PA4 and PA5 are used to drive I2C and control the screen. PA1 collects voltage and measures the voltage, and PA2 measures the current.
 
Note: When programming the serial port, remember to pull up BOOT0, TX to RX, RX to TX;
when designing the hardware, make rest and boot into buttons for easy debugging.
