I have verified that changing SD_SEL, SPI_FULL_SPEED, and SPI_HALF_SPEED in SFEMP3ShieldConfig.h does not fix the issue. I have verified that the MP3Shield also reports the same error with other FAT32 and FAT16 formatted class 10 microSD cards 1GB and 64GB. I have verified the error with the MP3Shield connected to another Arduino Uno. I have confirmed pin continuity with a DMM. I have re-flowed my solder joints to ensure proper connection. The library is installed as described here.Īfter loading the "SFEMP3Shield>Examples>FilePlayer.ino" file to the RedBoard, the Arduino serial monitor (at 115200 baud) reports:įree RAM = 2166 Should be a base line of 1029, on ATmega328 when using INTx I am using this SFEMP3Shield library because the recommended one did not compile with Arduino 1.8.13 on Windows 10 Pro. I have one MP3 file saved to the microSD card, and renamed to "track001.mp3". I carefully soldered the headers (PRT-00116) on the MP3 shield, according to the Technical Assistance page. I have a v15 board (DEV-12660) connected to a RedBoard (DEV-13975) and a class 10 microSD card (COM-15051) formatted as FAT32.
