Hi all,
For a project, I'm aiming to create a device which can play audio (44.1kHz, 16bit stereo wav) through headphones and simultaneously control a circuit (such as LED's for example).
The Adafruit Audio FX Sound Board - WAV/OGG Trigger with 16MB Flash (https://www.adafruit.com/product/2220) connected to an Arduino seems to me like the perfect match. I've gone through all documentation I could find as far as I know, but I'm left with a question.
Two requirement I have, is that I want to be able to upload the audio file + a parameters/settings file (txt,csv) into one memory space, and also save a log file (txt,csv) to the same memory.
Is it possible to read from/write to the flash memory of the Audio FX sound board through the UART serial connection between the soundboard and an arduino (uno for example)?
Kind regards!
Stef

I do not believe there is any way to do that. From what I've seen, the serial interface can list files, and control playback of those audio files.

Thanks Dave!
And do you know if it is possible with an Adafruit Music Maker Shield?
There is a SD card slot on there, can we communicate (read/write) to this SD card slot?

Yes. The SD card is read/write by the MCU.
