Musik Maker Shield can't read mp3 (or any other) files

Post by stalefish57413 »

Hello, im getting really frustrated and would apreciate the help.
When loading the example sketch i get "Could not open file track001.mp3" in the Serial Monitor.
Even thought the file is present and the SD card properly formated. (tried different filenames like "a.mp3" or just "a");
I'm also not able to write into a file on an SD card through the musik maker shield, althought the code works on an SD-Card-only shield i own.
I did account for the CS pin which is 7 on the musik-maker-shield and 8 on the SD-Card-only-shield.
Well at least SineTest does work fine, but thats not what i was going for :-(

More Tests:
SD does initialise, directory listing works.
Any form of file manipulation doesn't. So no reading writing or creating files.
I used the same code with another shield that has an sd-card-slot and it worked.

Post a photo of your hardware and we'll see if that tells us anything.

Here's a photo of the shield. Nothing fancy i just soldered the Pins on.
It will end up in a bigger project later on but first i need to get it running.
btw i did my testing on two seperate arduinos unos R3 with the same result.

As you can see solder job is solid, i build stuff regularly.

Ok i give up this thing clearly doesnt work.
Getting the sample code to work on a shield usually takes a minute.
I now work on it for 3 days without results, im done.
My suggestion is that the Hex-Inverter on the shield is broken.
That would explain why file listing works but reading and writing files doesn't.
What steps should i take to get a working replacement?
