[LCSC Training Camp] CW32 Voltage and Current Meter Construction

The LCSC Diwenxing is a development board designed using the Chipsource Semiconductor CW32, featuring excellent ADC performance. A voltage and current meter was designed using this board, capable of simultaneously measuring 0-30V voltage and 0-3A current, with good accuracy.

It supports 0-30V voltage ADC measurement with a display accuracy of 0.1V/0.01V; supports precise 0-3V ADC measurement with a display accuracy of 0.01V;
supports 0-3A current ADC measurement with a display accuracy of 0.01A; and can monitor
the voltage and current values ​​of the circuit under test in real time.
Using the CW32 development board is helpful for learning the circuit principles, ADC functions, timers, and interrupts of the CW32 development board, and for learning the KEIL MDK development environment. It includes a built-in analog calibration function, enabling debugging during product development without other peripherals. It also includes built-in analog voltage and current detection circuits, allowing for learning the principles of voltage and current measurement without other peripherals.
