pt100Read()

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

int pt100Read(uint8_t ch)

This example uses MPAINO-8A8R(T) with two F input modules. Select Temperature Input Module → F2. CH0 on F1 is 0; CH0 on F2 is 4.

void setup() {
  Serial.begin(115200);
}
 
void loop() {
  const int first = pt100Read(0);  // Read the F module PT100 temperature as tenths of a degree Celsius.
  const int second = pt100Read(4);  // Read the F module PT100 temperature as tenths of a degree Celsius.
  Serial.print(F("F1 CH0: "));
  Serial.println(first / 10.0F, 1);
  Serial.print(F("F2 CH0: "));
  Serial.println(second / 10.0F, 1);
  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.
