here I would like to introduce my project.
I've got this board: board, then this vs1053 breakout board: vs1053 As debugger I'm using lpc-link from LPCXpresso board.
First of all, I soldered out the microSD slot from the board to able to connect vs1053 break out board.
The project contains:
-> CMSIS v2
-> USB host driver (comming from NXP)
-> USB mass storage class (comming from NXP)
-> fat32 file system (FatFS version R0.09 adapted to using usb)
-> vs1053 patch 1.95 + flac
-> SPFD5408 driver (lcd)
Next steps are:
-> scan for files on usb-stick (incl. subfolders)
-> navigation with joystick and touch screen
-> tags extraction for MP3, FLAC and Ogg files.
And the some add-ons for vs1053:
-> activate I²S
-> connect cirrus cs8421 upsample ic to upsample 96kHz to 192kHz
-> dac: 2x wm8741 in dual differential mode
-> ad797 opamps as output filter to each wm8741
WM8741 should run in software control mode, so I²C.
Here are some pics:
The project is uploaded on my svn-server, so if you are interested in source code, I can provide url of them.
