Hi I'm new to this forum but I'll like some quick help please. It's for a college project

I've purchased a VS1003B Waveshare which seems very easy to use... But difficult to setup.

Link here: http://www.wvshare.com/product/VS1003B-MP3-Board.htm

I just added to my sketch this code:

Source: http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=11&t=65&p=308#p308

Editing this part:

Code: [Select]

#define MP3_XCS 6

/** Data Chip Select / BSYNC Pin */
#define MP3_XDCS 7

//** Data Request Pin: Player asks for more data */
#define MP3_DREQ 2

So I connect my module VS1003B accordingly to the constants set at the beginning of the code.

MOSI => pin 11
MISO => pin 12
SCLK => pin 13

Keep in mind, my module is a 3.3V module. So I need to adjust the tension coming from the Arduino with some pairs of 2.2K and 3.3K resistors. (Not for DREQ and MISO, Arduino represents 3.3V as HIGH pretty easily)

However after connecting my module and uploading the code, I could not hear anything. It's crazy !

So I measured DREQ pin with my voltimeter and it stays constant (more or less) at 0.07V is this ok? Why could this be? (And the Arduino still gets the HIGH and LOW of DREQ pin correct !!)

Why do you think it's not making any sound?

Sorry guys for not sharing any photos. At the moment I'm at the library and I don't have my setup with me.

I would appreciate any help.

Also, why does my module have two ground pins and two VCC pins of 3.3V ?

By the way, I have also try playing mp3, wav and MIDI... And I got nothing :/
