LCSC CW32 Voltage and Current Meter

1. Introduction and Functionality:
The core board uses the domestically produced Wuhan Xinyuan Semiconductor CW32 as the main controller. A digital voltage and current meter was designed and implemented, involving ADC technology and circuit measurement principles. It accurately converts analog voltage and current signals into digital displays for personal learning and subsequent testing.
2. Schematic Diagram, PCB Design, Software Programming, and Debugging:
This project is a replica of a project designed based on materials from the LCSC training camp. Schematic diagram design, PCB design, and testing were conducted at each stage of the software program.

5. Precautions:
Issues encountered during replication:
① Most components are through-hole, soldering is not a problem. Pay attention to the packaging of each component. The housing design can be more targeted, creating a more aesthetically pleasing shell and reducing interference.
② Debug the software for each experiment. Pay attention to the accuracy of the code when copying. Select the correct model before downloading. Restart the software to resolve download issues if there are bugs.
