qwiic mp3 trigger program upload

Sensors Sound & Audio

I am using the qwiic mp3 trigger in all of the IML Corp. new sound systems. The mp3 trigger operates as an mp3 player with only one file being manually selected. I need to adjust the volume. I have received very good assistance from SparkFun as to the program to be used to alter the volume. I have connected the mp3 trigger to my computer using a USB cable. I am using the suggested IDE library software for the qwiic mp3 trigger. I can not upload the program to the mp3 trigger. HELP! What am I missing in the setup of the IDE. Is there a tutorial that will walk me through the inclusion of a SparkFun board. I do not have a problem sending files to the mp3 trigger SD card.

Hi Lee.

You can’t upload to the Qwiic MP3 Trigger, it’s just a MP3 player and doesn’t run your code onboard. The USB connector on these is just for supplying power or for moving MP3 files onto the SD card on the board.

You need to upload your code to a microcontroller like Arduino and then attache the Qwiic MP3 Trigger to that microcontroller. The Arduino will then send commands over too the Qwiic MP3 to be executed.

Hello, I found this thread interesting but have some other questions about the Qwiic MP3 Trigger.

I need a player hardware that automatically loops a file (Just one) as quick as it gets power.

I want to play a forest ambience at a relaxroom, and it should always be running, if no one breaks the power.

Is this possible with the Qwiic MP3 Trigger only?

Thanks a lot in advance.

If you want to loop the file a specific number of times you’d need additional logic to do that, we don’t carry a board that will count the number of loops and stop at a given number all on it’s own.

If you just need to loop a file forever, I don’t recall the Qwiic MP3 Trigger being able to do this, but I know for a fact our [WAV Trigger has this capability. All you need to do is jumper one of the track triggers closed and the board will play that track on loop forever as long as there’s power to the board.](https://www.sparkfun.com/products/13660)
