I have a lot of the functions working, play/next/loop etc. but I can't get the functions that return information to work.
maxSongs = myDFPlayer.readFileCounts(DFPLAYER_DEVICE_SD);
Serial.println(myDFPlayer.readFileCountsInFolder(1));
Serial.println(myDFPlayer.readVolume());
Serial.println(myDFPlayer.readVolume());
are some that don't work.
Any Ideas?
