UART波特率计算器 — 公式
## ADC Resolution and Digital Conversion
An ADC maps a continuous voltage range to discrete digital codes. The resolution determines the smallest detectable voltage change.
### Formulas
**Step Size = V_ref / 2^N**
**Digital Code = floor(V_input / Step Size)**
**Quantization Error = V_input - Code x Step Size**
The maximum quantization error is +/- 0.5 LSB.

计算示例
10-bit ADC with 3.3 V reference, input 1.65 V.
- Step size: 3.3 / 1024 = 3.223 mV
- Digital code: floor(1.65 / 0.003223) = 512
- Reconstructed: 512 x 0.003223 = 1.6504 V
- Error: |1.65 - 1.6504| = 0.4 mV
