Reading/writing values to SD card

Other Hardware Storage
1

I have a two functions within a sketch. The first writes calibration values to an SD card as a csv file. The second function reads the csv file on start up. This is the code for the functions: (The entire sketch is around 3000 lines, so I'll spare you the rest of the code and defining variables. The sketch works, this is just an added feature that has a bug.)

void Read_Calibration_Values_SD() {
  float CALValuesTemp[9];
  File dataFile = SD.open("CAL_Values.txt");

  // if the file is available, read the array data from it
  if (dataFile) {
    int i = 0;
    while (dataFile.available() && i < 9) {
      CALValuesTemp[i] = dataFile.parseInt();
      i++;
    }
    dataFile.close();

    InAirwayPressureCAL = CALValuesTemp[0]; SerialUSB.print("InAirwayPressureCAL "); SerialUSB.println(InAirwayPressureCAL);
    ExpAirwayPressureCAL = CALValuesTemp[1]; SerialUSB.print("ExpAirwayPressureCAL "); SerialUSB.println(ExpAirwayPressureCAL);
    GasManifoldPressureCAL = CALValuesTemp[2]; SerialUSB.print("GasManifoldPressureCAL "); SerialUSB.println(GasManifoldPressureCAL);
    VoltageCAL = CALValuesTemp[3]; SerialUSB.print("VoltageCAL "); SerialUSB.println(VoltageCAL);
    VTCAL = CALValuesTemp[4]; SerialUSB.print("VTCAL "); SerialUSB.println(VTCAL);
    VTOrificeCAL_PC = CALValuesTemp[5]; SerialUSB.print("VTOrificeCAL_PC "); SerialUSB.println(VTOrificeCAL_PC);
    VTOrificeCAL_VC = CALValuesTemp[6]; SerialUSB.print("VTOrificeCAL_VC "); SerialUSB.println(VTOrificeCAL_VC);
    ExtraGasGAIN = CALValuesTemp[7]; SerialUSB.print("ExtraGasGAIN "); SerialUSB.println(ExtraGasGAIN);
  }
  else SerialUSB.println("No Calibration file found");
}


void Write_Calibration_Values_SD() {
  myFile = SD.open("CAL_Values.txt", FILE_WRITE | O_TRUNC); // write alarm to SD card
  myFile.print(InAirwayPressureCAL); myFile.print(",");
  myFile.print(ExpAirwayPressureCAL); myFile.print(",");
  myFile.print(GasManifoldPressureCAL); myFile.print(",");
  myFile.print(VoltageCAL); myFile.print(",");
  myFile.print(VTCAL); myFile.print(",");
  myFile.print(VTOrificeCAL_PC); myFile.print(",");
  myFile.print(VTOrificeCAL_VC); myFile.print(",");
  myFile.print(ExtraGasGAIN); myFile.print(",");
  myFile.close();

  SerialUSB.print("Write Calibration Values SD -- ");
  SerialUSB.print(InAirwayPressureCAL); SerialUSB.print(",");
  SerialUSB.print(ExpAirwayPressureCAL); SerialUSB.print(",");
  SerialUSB.print(GasManifoldPressureCAL); SerialUSB.print(",");
  SerialUSB.print(VoltageCAL); SerialUSB.print(",");
  SerialUSB.print(VTCAL); SerialUSB.print(",");
  SerialUSB.print(VTOrificeCAL_PC); SerialUSB.print(",");
  SerialUSB.print(VTOrificeCAL_VC); SerialUSB.print(",");
  SerialUSB.println(ExtraGasGAIN);
}

The problem I'm having is that when I read the csv file every other value is 0.
This is what's being written to the SD card:

1.00,2.00,1.00,4.00,6.00,3.04,1.03,2.00,

However, this is what's being read by the SD card:

InAirwayPressureCAL 1.00
ExpAirwayPressureCAL 0.00
GasManifoldPressureCAL 2.00
VoltageCAL 0.00
VTCAL 1.00
VTOrificeCAL_PC 0.00
VTOrificeCAL_VC 4.00
ExtraGasGAIN 0.00

Notice every other value is a 0. What's the obvious thing that I'm missing?

CALValuesTemp[i] = dataFile.parseInt();

You are parsing integers but you wrote them as floats.

Well don't I feed dumb. Problem solved. This is what happens when you ask ChatGPT to write code for you:)

Thanks for the quick reply.
