Well, because the IR sensor I need runs off of 5V; if I can get 5V TTL
then it's just a matter of hooking it up...  Otherwise, I will need
more components to provide 5V.  I'm thinking one pin to power it, one
pin to sense it.  Simple....

OTOH, if one of the hardware folks has any suggestions for connecting
a Vishay TSOP 1738 or similar to the 3.3V GPIO on the tx7xx0 boards
I'd love to hear them....
