Out of curiosity, how many files can be stored and played back on the Qwiic MP3 trigger using the F001.mp3 naming convention?
It is pretty clear that the direct triggers are T001.mp3 - T010.mp3, but I was wondering if there were any limits to the files that can be played using the other naming pattern.
It looks like you can address up to 255 tracks, but if you use the next command, you can keep playing tracks numbered over 255.
You can use the PLAY_TRACK and PLAY_FILENUMBER command for up to 255 individual tracks per the notes in the [Qwiic MP3 Trigger Firmware.
We will probably get that added to the Hookup Guide for better visibility.](Qwiic_MP3_Trigger/Firmware/Qwiic_MP3_Trigger/Qwiic_MP3_Trigger.ino at master · sparkfun/Qwiic_MP3_Trigger · GitHub)
