IanalogReadf() converts the analog input value to the specified floating-point range.

float IanalogReadf(uint8_t ch, float min, float max)

void setup() {
  Serial.begin(115200);
}
 
void loop() {
  float voltage = IanalogReadf(A0, 0.0F, 10.0F);  // Map the analog input value to the specified floating-point range.
  Serial.println(voltage, 2);
  delay(500);
}

• min and max define the conversion range of the return value, not the actual electrical input range of the sensor.
• Iscalef() limits the result to the specified output range.
• Setting min greater than max reverses the output range. Example: IanalogReadf(A0, 100.0F, 0.0F).
• MPINO and MPAINO have different raw ADC ranges. Always use ch appropriate to the selected board.
• Set the MPAINO analog input module's DIP switches and wiring to match the actual input type.
• This command performs only linear range conversion. Sensor error compensation, open-circuit detection or 4~20mA software Cut requires separate processing.
