FX Sound Board 2mb Serial play

Post by rhartl »

I have an fx sound board 16mb that I am trying to use via UART. Before I flashed the memory the demo program menucommands was able to identify the board, but was unable to read files using the listing option. My computer showed that the files were there. So I decided that I needed to re flash the drive. I did that and now the menucommands program returns "Not found" when calling reset. What do I do now?

Is the ADAFRUITSFX folder still showing up on the PC?

Accessing with Windows 10: yes.
Accessing with Windows 11: no.

What exactly was done here?

It showed up OK on the Win11 machine prior to this?

So I downloaded the 16mb image from your web site. Downloaded the program that you recommend to flash the image, win32Diskimager, and flashed the image to the sound card. Then I transferred the ogg files I want to play to the freshly flashed fx card. Confirmed that they all transferred. I then connected the card to my Arduino mega using the ports recommended: reset 4, tx 5, rx 6, ug to ground. Connected the external amp that I am using to output r + and r - ( the files are all mono). Connected vin and ground to an external power supply at 5 volts. This also sends power to the mega. Loaded menucommands from examples and compiled and ran it. Looking at the serial monitor I get “Adafruit Sound Board” /cr “Not found”.

One thing I should correct is that I am working with the 16mb fx card not the 2mb as is in the title of the thread.

So I have made progress over the weekend. For reasons I don’t completely understand changing the tx, rx and reset ports has fixed the problem of identifying the fx sound card. The menu comes up. But listing the files still shows 0 files.

Also using a higher quality USB cable fixed the problem of Windows 11 not seeing the sound card. Tried deleting the files and reloading them, with the same result when I tried to list the files. The files are mono ogg files with file names T0-T9. If I click on them in Windows they play fine through the media player.

The ogg files are 22k sample rate, 16 bit pcm, mono. I can load them from the fx sound card and play them with Audacity.

Try testing with the sample audio files in the Demo_Tracks.zip available here:
https://learn.adafruit.com/adafruit-aud ... udio-files

That'll help rule out it being something with the ogg files currently being used.

Loaded the sample audio files on the card and ran menucommands. Using Listing command "No Files". Trying play any of the tracks with #number command I get track failed to play.

Could this be power related? Keep in mind the board can *not* be powered via the data USB cable connection and also be used for playback at the same time:

Are you powering it separately once the files have been copied over?

Should be receiving power via vin and ground, when I am running menucommands. I unplug the USB cable before testing it.

The interesting thing about this is that a week or so prior to all of these problems it was working fine playing my ogg files. So something happened and I am not sure what. I think in that period I had to change to the mega to accommodate all of the libraries I am using.

OK, so not power. Thanks for confirming.

When you plug the board back in to the PC, do the files show up again in the folder? Like the PC sees everything OK, but not the serial control / menucommand code?

Yes. If I plug in the USB cable I can see the files. And if I open a file with Audacity it will play.
