ADC 输入和完整的输入调节电路。ADC 针对双极测量进行配置，此测量中的最终转换结果是正负 ADC 输入电压之间的差分电压。 双极 GND 基准输入信号必须进行电平转换，并通过运算放大器进行衰减，这样输出将偏置为 VREF/2，并且其差分电压在 ADC 的 ±VREF/2 输入范围内 ...

The ESP8266 has become one of those ubiquitous parts that everyone knows. However, the new ESP32 has a lot of great new features, too. If you want to take the ESP32 for a spin, you should check out ...

[Simon Monk] got frustrated with bad ADC performance when tinkering with an ESP32 board, and decided to put three of the nowadays-iconic boards to the test – a classic ESP32 devboard, a Pi Pico with ...
