pt100Read() returns the PT100 sensor temperature as an integer in 0.1℃ units.

int pt100Read(uint8_t ch)

void setup() {
  Serial.begin(115200);
}
 
void loop() {
  int pt0 = pt100Read(0);  // Return the PT100 sensor temperature as an integer in 0.1°C units.
  int pt4 = pt100Read(4);  // Return the PT100 sensor temperature as an integer in 0.1°C units.
 
  Serial.print("PT0: ");
  Serial.println(pt0);
 
  Serial.print("PT4: ");
  Serial.println(pt4);
 
  delay(500);
}

• pt100Read() is a convenience command for the MPAINO PT100 input module.
• Conversion of the return value to actual temperature follows the existing PT100 input module behavior.
• Verify PT100 wiring and module connection order against the product manual and schematic.
• If insufficient SRAM prevents creation of the internal IADC object, 0 is returned.
