Sorry for my english and sorry I'm a newbie in programming C.

I solved.

int count = 0;

void loop() {

  u8g.firstPage();
  do {
    draw();
  } while ( u8g.nextPage() );
  delay(2000);
  count++;
  
  if (count == 300) {
    myFile = SD.open(filename, FILE_WRITE);

    myFile.print(timeStamp());
    myFile.print(" ");
    myFile.print(dht.readHumidity());
    myFile.print(" ");
    myFile.println(dht.readTemperature());
    // close the file:
    myFile.close();
    Serial.println(" done.");
    count = 0;
  }
