CW32 Voltage and Current Meter

1. Project Function Introduction:
A voltage and current meter based on the CW32F030C8T6 chip
. 2. Project Attributes:
LCSC training camp project, for learning and familiarizing oneself with the CW32 chip from domestic Chipsource Semiconductor.
3. Open Source License
: GPL 3.0
4. Hardware Part:
The expansion board's appearance is shown in the image, using LCSC's color silkscreen printing.
The 3D shell is shown below; the top cover is open and has M2 screw holes, with recessed areas for the three buttons for easy operation. Because the shell itself is not very tall, there is no space reserved for the front panel.
One issue is the LED indicator lights. The placement of the two LED indicator lights wasn't considered much at the time of installation, and it was only after plugging in the CW32 that it was discovered that the CW32 board directly blocks these two LEDs, making them invisible from directly above, which is a bit awkward.
5. Software
: There's not much to say about the software; I didn't make any changes and directly used the official code. However, I encountered an error when using the official code directly. I'm not sure if it's a Keil version issue, but it couldn't recognize the WEAK decorator in cw32f030_systick.c, so I had to remove it.
Ultimately, I only tested the voltage measurement function because I didn't have suitable wires for the current connection port. I used DuPont wires to connect the voltage measurement port and tested its functionality as shown in the video.
