All we need is to write code that gets our Arduino board to act as traffic controller and transfer audio data from the MicroSD card to the VS chip and playing out through the headphone socket the outer of the two. If you do, the VS chip will likely blow up. However, the solution is to use a number of DC-blocking capacitors.
The addendum PDF shows you the circuit required. VS IC. In addition to being able to decode all the most common audio formats - including the advanced features of newer AAC files - functionality of this IC can be greatly expanded just by loading a bit of extra software to its RAM memory.
In addition to being able to decode all major audio formats, VS is capable of recording in three different audio formats, from lossless bit PCM to highly compressed, yet high-quality Ogg Vorbis files.
For the best headphone listening experience the VS includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. This option can naturally be turned off when required. All in all, VS is an easy-to-use, powerful workhorse for audio playback and recording applications. You can read the specification of VSb here. Very good library and easy to understand — great work, Bill!
Could you tell me how to reset the mp3-shield to the state before I did the begin-command? Sorry for my noobish post, but I am still a beginner. Would be very cool if you could help me! Thanks in advance. The motor shield needs to use pins 3,8,9,11,12,13 to drive the two H-bridges.
The only feasible options to to use a second Arduino to run the MP3 shield, and exchange commands between them over serial. Ahhh, no good news. But hey, thanks for that quick answer, Bill. Keep up the good work. No, the decoder can only handle one MP3 stream or midi stream at once. I have downloaded all drivers and software, but cannot get any sound to play. I have tried both your way of changing! Neither are getting results though.
Any idea? I named the SD file track I am very new at this, is there anything you could recommend or that i may be overlooking for the mp3 shield??
Trey, that means you did not unzip and copy the library into the Arduino libraries folder correctly. The path of the. Thank you.
That solved it and it is working perfectly! Great code. My overall goal is to receive CAN input to the CAN shield, and depending on the speed of the car, play a different pitch sound from mph through the mp3 player! You have the same problem as Tom, the shields are not compatible. That was what I came up with when I glanced at the two spec sheets. The easier thing to do is to have two separate Arduinos talking to each other over serial. Ok great. That would have taken my 3 hours! Also, do you know if it is possible to integrate a gas pedal like in video games to the arduino?
Or any other components I would need? Nice work! Not sure hgs, you would have to compare the spec sheets of the chips. If your chip supports the same, my guess is yes. Hi, thanks for making this great library. In case anyone else is still using this older shield, the library can be modifed to work with this shield by just changing a few lines. Hmm, thanks for posting the difference.
I may have to add some compatibility in for the old boards. You must be logged in to post a comment. This site uses Akismet to reduce spam. Learn how your comment data is processed. Chris says:. January 29, at am. Where the VSdsp's RAM can additionally be loaded with externally provided firmware and executed, also known as patches or plug-ins, over the SPI port and executed.
Allowing updates to the VSDsp into its volatile memory after each reset. These updates may be custom features or accumulated patches. The filenames are kept short as SdCard only support 8. Error Codes typically are returned from this Library's object's in place of Serial.
As to both save Flash space and Serial devices may not always be present. Where it becomes the responsibility of the calling sketch of the library's object to appropiately react or display corresponding messages.
The code has been written with plenty of appropiate comments, describing key components, features and reasonings in Doxygen markdown style as to autogenerate this html suppoting document.
