Here you will find everything you need to make the Daisy mp3 player. All the source files, hex files, EAGLE cad files, and documents are here. This is the official Make: mp3 player available here or at the Make: store.

The Daisy is a multipurpose sound player for embedded applications. It can be used as a standalone personal music player,as the sound for an art project, in a kiosk, as a museum tour guide, in a toy, or anywhere that high quality embedded audio is desired. It uses MMC or SD flash memory cards so storage size is unlimited. It has several interface modes for either human or machine control.

The Daisy is based on the Microchip PIC18F45j10, which is a new family of PIC microcontrollers. They are capable of running at a full 40MHz at 3.3 volts, which makes them ideal for this application. Also, most of the pins are 5 volt tolerant, easing interface with other microcontrollers. The other chip on board is a VS1011 from VLSI, Finland. It is an .mp3 and .wav decoder chip, a DAC, and a headphone amplifier all in one 28 pin package. I’ve been fooling around with this family of decoders since 2001 and I have never found an mp3 file it couldn’t decode... and the sound is very good!

All of the firmware was written using CCS PCH C compiler. The CAD files were made with EAGLE cad. The manual was written with OpenOffice.
