Hi all,
I have recently been playing around with the arduino and audio, using the WTV020SD for play back. It is tedious to have to convert audio files into the AD4 file type, and the breakout board is very difficult to work with (e.g. it is very sensitive to types of SD cards used and voltage drops). To have the project I have devised (an alarm clock), easier for other people to use by simply putting MP3 files onto a SD card or USB stick, I would love to be able to create a PCB with MP3 playing capabilities. I know there are loads of MP3 breakout boards out there, mainly using the VS1053 chip, but I would like to be able to incorporate the audio processor, for example the VS1053, into my own PCB. This would look neater and take less space. You can argue if it is cheaper or not. Anyways, I cannot find anyone who has taken on this issue and published how to do it. So I ask, does anyone have a design/schematic that shows how to use, for example an VS1053 chip and control it via an arduino? Also, any necessary libraries to control the VS1053 would be great.
Many Thanks
