CW32 Voltage and Current Meter

Overview

For hardware selection,

this project uses the CW32 as the main control MCU. Its main features include strong anti-interference capabilities, a high-speed, high-precision ADC, and multiple reference voltages, which are beneficial for accurate voltmeter and current meter measurements.

The circuit design

is based on the training camp's design scheme, replacing through-hole components with surface-mount components, resulting in higher accuracy and smaller package size.

Experimental verification:

The program was written according to the training camp's software tutorial. Verification shows that the circuit can perform measurements normally with minimal error.

Let's take a look at the meaning of these formulas~~
1 x 1 x 1 means that if you do the same thing every day, the final result will still be 1. 1.1 x 1.1 x 1.1 means that if you change or learn a little bit every day, it will eventually add up to a lot.
