Hi,
how can i play Audio from SD Card with LPC1786 (Cortex M3) ?
Thanks
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 ...
