#LCSC Training Camp# Voltage and Current Meter Designed Based on CW32F030C8T6

This project is a practice project for participating in the LCSC training camp. It records my learning process and some thoughts, and may not be entirely accurate.
To see the original version, please go to the CW32 Digital Voltage and Current Meter Training Camp Project Tutorial Document | LCSC Development Board Technical Document Center (lckfb.com).
The reason why the cost of replicating this project varies from 30-50 is mainly because the training camp requires the use of the LCSC Ground Star Development Board LCKFB-DWX-CW32F030C8T6_LCSC Development Board-LCKFB-DWX-CW32F030C8T6 Chinese Datasheet_PDF Manual_Price - LCSC Mall (szlcsc.com). The price with a coupon is 0.9 yuan, and if you buy it yourself, it's 9.9 yuan. In addition, the training camp recommends through-hole resistors and capacitors. Considering that I had some 0603 surface-mount resistors and capacitors on hand, I changed them all to surface-mount components.
The Ground Star image is as follows:
 
I. Circuit Part
1. Main controller, LCSC Ground Star Development Board
2. Power supply.
It can be powered via Type-C through the development board, or connected to an external 6-40V DC power supply. The original author specifically selected a high-voltage LDO, SE8550K2-HF. The 
components include: 3. Voltage sampling circuit;
4. Current sampling circuit and current measurement port
; 5. Voltage calibration;
6. Current calibration; 7.
Digital tube display;
8. Buttons and indicator lights ;
9. Drawing the PCB and placing the training camp logo and Chip Source logo;
10. Designing the casing;
11. Designing the faceplate; 12. PCB fabrication
and soldering;
13. Assembling the casing
. The faceplate design was finished, but I forgot to place the order. Just make do with it. There's still a lot of room for improvement.
II. Software:
I wanted to install a genuine Keil, downloaded it following the steps for a week, but couldn't find the registration code, so I eventually had to crack and register it. I also couldn't get the configuration file working. I just found the program and burned it.
