CW32 Voltage and Current Meter

Project Overview:
This project originates from the CW32 & LCSC Development Board Voltage and Current Training Camp. It's a voltage and current measurement expansion board implemented using the LCSC CW32F030C8T6 development board.
Features
include: measuring 0~30V voltage and 0~1.5A current;
viewing results via a 3-digit LED display;
voltage or current calibration via buttons to improve measurement accuracy; wide power input
voltage

, which can be shorted with jumpers for analog measurement;
dual-row 3-digit LED display for simultaneous voltage and current measurements;
power indicator and MCU normal operation indicator for accurate measurement;
specific value calibration for more accurate measurements;

Note:
Due to the lack of a regulated power supply, the demonstration used analog measurement with resistor-based voltage division, resulting in some deviation between the measured and actual values.
