This project relates to PIC18F series using IAR PIC18EW complier (HICC or CC2 or similar example accepted).
I am seeking article from mazagine, experience by someone, links that demostrate how to
(a) Coverts mp3 or common format containing simple sound or music including spoken word into compressed format file. Perfer to limits bandwidth sufficient for small PCB speaker or at least peizo.
(b) Transulates the compressed format file into 8, 10 or 12 bits data output via SPI where external DAC is driven.
(c) Descrition on how this is done if possible with code examples.
(d) If possible but not required, cheap audio amp circuit between DAC and small speaker about 5-10mm dia.
Tested example from other controller will be considered, I can transfer and modify the C or C++ program into microchip PIC18F series. I quite good in Basic, C, C++ and C# from compact framework.
Anyone offer an inputs?.
