[sdiy] MIDI specifications round 2

[Blitzcraig]

A lot of helpful info guys, thanks.

I'm not familiar with UART's, but I'm assuming they're IC's that are used
for Asynchronous transfer's, add start/stop bit, etc.
Looking over my microcontroller a little more, I have notice that it has a
SCI built in.  All I would have to do is set the baud and write to the
register and it should take care of the start/stop bit for me.  I think I
should be able to handle the serial stuff from here.

I'm still a bit confused about the pin's, I'm not sure what the current
loop is/does.  From these schematic/diagrams shown, it looks like my data
should go through two inverters through a 220ohm resistor?  I'm not sure
why you would do that other than to delay the data, why?  ok, and the
other pin is tied high through a 220ohm resistor... this is the twisted
pair that's mentioned right?  The middle pin ties to what, I think this is
confusing because of my lack of current loop knowledge.

thanks for all the help,

-Joe
