Currently I'm writing a new line to the end of the file. How do I have to change my code (below) to write to the FIRST line of the file? File dataFile = FileSystem.open("/tmp/datalog.txt", FILE_APPEND); if (dataFile) { dataFile.println(dataString); dataFile.close(); }

Write to first line of file

myFile = SD.open("test.txt", FILE_WRITE); instead of FILE_APPEND
