ADC (Analog-to-Digital Conversion)

LibXR::ADC provides a platform-independent interface for analog-to-digital conversion (ADC), used to read analog input voltage values. It is suitable for applications such as voltage monitoring and sensor data acquisition.

Interface Definition​

class ADC {
public:
  ADC() = default;

  // Reads the ADC voltage value in volts (float type)
  virtual float Read() = 0;
};
  • Read() is a pure virtual function, and must be implemented by subclasses to provide specific sampling logic;
  • The return value is typically within the range of 0 to 3.3V, or other ranges supported by the chip;
  • The interface is simple and clear, making it suitable for platform abstraction and analog signal reading.

Feature Summary​

  • Provides a unified interface for reading analog voltage;
  • Avoids platform differences, facilitating upper-layer logic reuse;
  • Suitable for input from sensors such as temperature, voltage, and light;
  • All platforms must implement the Read() method to perform sampling.
