a newbie here
I was looking for some information on GPIO and McBSP
Can some one explain me difference/similarities/general concepts...some
pointer will be good too

GPIO = General Purpose I/O
McBSP = Multi-channel Buffered Serial Port
GPIO would be used for things such as turning an LED on/off or perhaps
enabling/disabling some other device. In general it is good for things
that have on/off states.
The McBSP is for doing communication. It could be used to talk to an
A/D and/or D/A. You could also use it as a chip-to-chip connection to
send data back and forth between two devices. It has a clock,
frame-sync, and data line for both transmit and receive.
Sometimes people will use GPIO to do communications. This is often
called "bit banging" because you need to do a whole bunch of writes to
the GPIO to mimic things like clocks, etc. Generally "bit banging" is
done in order to save money by squeezing into a cheaper part that
doesn't have all the interfaces you need.

You could find much details of McBSP in Peripherals Guide at
Alternatively, TMS320C6000 DSP Multichannel Buffered Serial Port
( McBSP) Reference Guide (Rev. G) would also help.

looks like macbsp is something like gpio but with some more control signals.am i right?
