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

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.
