Audio Using LPC1768 (Cortex M3)

Thanks Andy,
I found an example for Read / Write from to SD card. what did i not understand he used the libraries of SPI and also used UART in the code, I don't understand why we need UART if the data were transferred via SPI !

Me neither :-) Ask the author.

So you need to look into it to see what, exactly, the UART is being used for.

We have no idea what example you're talking about - so can't comment. As 42Bastian Schick said, you would have to ask the author for specific details ...

However, it is always very useful to have a UART available for diagnostic / status / debug / trace outputs; sometimes also for configuration & control ...
