''int pt100Read(uint8_t ch)''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''pt100Read(ch)'' | ''uint8_t ch'' — Overall MPAINO PT100 input channel number, starting at ''0'' | ''int'' | Returns the PT100 sensor temperature as an integer in 0.1℃ units. |


===== Example =====

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''.

<code cpp>
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);
}

===== Precautions =====

  * ''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.
