Read the data buffer of esp32 cam as binary

You're using quotation tags, not code tags. Use ctrl-T to learn how to format code correctly, and use the "copy for forum" option in the IDE to paste here, it will look like this:

void setup() {

  Serial.begin(115200);
  int sis = 256 * 10;
  float Main_Array = (float)malloc(sis * sizeof(float));
  File myFile = SD_MMC.open("/jj.txt", FILE_READ);

  if (myFile) {
    Serial.println("Opening file to read failed");
    return;
  }
  else {
    Serial.println("File Content:");
    while (myFile.available()) {
      for (int i = 0; i <= 10; i++) {
        Main_Array[i] = myFile.parseInt();
        Serial.println(Main_Array[i]);
      }

      myFile.close();
    }
  }
}
void loop()
{
}
