I am trying to load and read back WAV audio files from the SD card on a WIO Terminal.
I am using a 16GB micro SD card. I have tried both FAT32 and exFAT formats.
When I execute the Arduino Seeed_Arduino_FS “listfiles” example, the listing
comes back as empty. I can see the WAV files I loaded when I mount the SD card with my Mac.
Anyone have an idea on why these files do not show up in the listing?
There are no errors, just a listing that shows no files in the “/” root folder.
Thanks
